+
+	[ms]: Offer advice to users of PDF who want a table of contents
+	at the front of the document.
+
+	* doc/groff.texi (ms Document Structure): Move mention of
+	pdfjam(1) from here...
+	(ms TOC): ...to here, and identify alternatives, including
+	gropdf(1)'s `pdfswitchtopage` macro.
+
+	* doc/ms.ms (General structure of an ms document):
+	(Creating a table of contents): Similar.
+
+	Fixes <https://savannah.gnu.org/bugs/?64278>.  Thanks to Michał
+	Kruszewski for the report.
+
+2023-06-01  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[docs]: Migrate terminology to "scaling unit".
+
+	...from "scaling indicator".
+
+	Fixes <https://savannah.gnu.org/bugs/?60957>.  Thanks to Ingo
+	Schwarze for the discussion.
+
+2023-05-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[docs]: Revise discussion of fonts.
+
+	* doc/groff.texi:
+	- Rename node/section "Fonts and Symbols" to "Using Fonts".  Add
+	  giant new introduction, properly establishing terminology.
+	- Rename node/section "Changing Fonts" to "Selecting Fonts".
+	  Shift location of `.fn` and `.sty` register documentation.
+	  Rewrite presentation of `ft` and `\f`.  Discuss typeface
+	  selection by mounting position and font (or style) name
+	  together; since arguments to these formatter instructions are
+	  always interpreted as mounting positions first, it doesn't
+	  make much sense to me to present them separately, and the new
+	  introduction provides the necessary background.  Tighten
+	  example.  Document that current and previous font selections
+	  are environment properties.
+	- Add several concept index entries.
+	- Do more migration from "symbol" and "glyph" names to "special
+	  character" names.
+
+	* man/groff.7 (Using fonts): Introduce new section, synced with
+	the renamed node from our Texinfo manual above.
+
+	Fixes <https://savannah.gnu.org/bugs/?62973>.
+
+2023-05-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[docs]: Revise "Page Layout" material.
+
+	* doc/groff.texi:
+	- Recast generally.
+	- Describe behavior of `pl` in more detail.
+	- Migrate terminology from "scaling indicator" to "scaling
+	  unit".
+	- Stop discussing page margins in the context of the `pl`
+	  request.
+	- Move concept index entries regarding margins from here to
+	  "Traps".
+	- Move discussion of `pn` request to precede `tl` request.
+	- Add concept index entries.
+	- Recast description of `tl` request.  Migrate terminology from
+	  "justification" to "alignment".
+	- Recast description of `lt` request.  Describe behavior in more
+	  detail.
+	- Recast description of `pc` request.
+	- Add example of `lt` and `tl` usage.  Add forward reference to
+	  "Traps", mentioning page header and footer traps.
+
+	Fixes <https://savannah.gnu.org/bugs/?55124>.  Thanks to Dave
+	Kemper for the report.
+
+2023-05-22  Dave Kemper <saint.snit@gmail.com>
+
+	[docs]: Correct minor punctuation, grammar, and spelling issues.
+
+	Also remove a couple instances of unnecessarily telling the
+	reader to note something.
+
+	* doc/groff.texi:
+	* man/groff.7.man:
+	* man/groff_char.7.man:
+	* man/groff_diff.7.man:
+	* man/roff.7.man:
+	* src/roff/nroff/nroff.1.man: Do it.
+

+	more fixes.  --GBR]
+
+2023-04-22  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[docs]: Attempt to further clarify end-of-sentence detection.
+
+	* doc/groff.texi (Sentences):
+	* man/roff.7 (Concepts): Do it.
+
+	Fixes <https://savannah.gnu.org/bugs/?64091>.  Thanks to Ingo
+	Schwarze and Dave Kemper for the report.
+
+2023-04-14  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[docs]: Minimally document `tag`, `taga` requests.
+
+	* doc/groff.texi (Postprocessor Access):
+	* man/groff.7 (Request short reference): Do it.
+
+	Fixes <https://savannah.gnu.org/bugs/?62695>.
+
+2023-04-11  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[docs]: Fix typos.
+
+	* doc/groff.texi (ms basic information):
+	* doc/ms.ms (Basic information): Do it.
+
+	Fixes <https://savannah.gnu.org/bugs/?64032>.  Thanks to an
+	anonymous reporter.
+
+2023-03-07  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/groff.texi (Operators in Conditionals):
+	* man/groff.7.in (Conditional expressions): Clarify how the
+	output comparison operator is recognized.
+
+	Fixes <https://savannah.gnu.org/bugs/?63812>.  Thanks to John
+	Gardner for the report.
+
+2023-03-06  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Use a better type for symbol hashes.
+
+	* bootstrap.conf: Add "stdint" module to ensure that the
+	`uintptr_t` type is available.
+	* src/include/symbol.h: Include <stdint.h> for `uintptr_t`.
+	(class symbol):
+	(symbol::hash): Change return type from `unsigned long`, which
+	causes build failures on 64-bit MinGW, to `uintptr_t`.
+	(symbol::hash): Use a C++ type cast, not a C-style one.
+
+	Thanks to Bruno Haible for reporting the build failure in the
+	64-bit MinGW environment, and for suggesting a remedy.
+
+2023-03-06  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[groff]: Revise a test to be more revealing.
+
+	* src/roff/groff/tests/initialization_is_quiet.sh: Stop using
+	"set -e".  Instead use `fail` variable and `wail` function (and
+	lowercase names for our internal variables) like many of our
+	other tests.  If the "unset" shell built-in fails, skip the
+	test (prompted by /usr/xpg4/bin/sh on Solaris).  Attempt every
+	groff locale, with and without compatibility mode initially
+	enabled, instead of stopping at the first failure.  Report
+	standard error and standard output content separately.  Use
+	groff's `-a` flag to prepare the standard output, for
+	readability.
+	* PROBLEMS: Document that this test might be skipped rather than
+	failing on Solaris.  (What actually happens depends on which
+	shell you run it with, and we advise a variety of approaches.)
+
+	Thanks to Bruno Haible for feedback regarding mysterious
+	failures of this test on GNU/Hurd and NetBSD systems.
+
+2023-03-06  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* bootstrap.conf (gnulib_modules): Add "stdbool-c99" per
+	recommendation from Bruno Haible.
+
+	Fixes build problem on Solaris using Sun compiler.
+
+2023-03-06  Bruno Haible <bruno@clisp.org>
+
+	* Makefile.am (AR): Remove hardcoded value. Let Automake use the
+	value from config.status.
+
+	{Fixes build problem on 64-bit AIX.  Problem appears to date
+	back to commit 5fec19d453, 2014-08-15. --GBR}
+
+2023-03-06  Bruno Haible <bruno@clisp.org>
+
+	* arch/misc/misc.am (shdeps.sed): Rename target from this...
+	($(SH_DEPS_SED_SCRIPT)): ...to this, to work better with make(1)
+	on FreeBSD, NetBSD, and AIX.
+
+2023-03-01  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[build]: Discard now-unneeded Autoconf macro and variables.
+
+	* configure.ac: Stop calling `GROFF_POPPLER`.  Stop populating
+	the Automake conditional `HAVE_PDFTOOLS`.  Eliminate chatter
+	about their availability in the configuration report.
+	* m4/groff.m4 (GROFF_POPPLER): Delete.
+
+2023-03-01  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_URW_FONTS_NOTICE): Adapt wording of notice
+	to presence and identity of Ghostscript interpreter command.
+	Clarify that it is gropdf(1) specifically that traverses the
+	Ghostscript search path reported by its "-h" option.
+
+	Continues <https://savannah.gnu.org/bugs/?63808>.  Thanks to
+	Deri James for the ongoing discussion.
+
+2023-02-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[devpdf]: Revise tests.
+
+	* font/devpdf/tests/check-default-foundry.sh.in: Test only the
+	base 14 fonts of the PDF standard unconditionally.  Test the
+	remainder from the set of 35 commonly distributed only if a
+	Ghostscript interpreter was detected at configuration time,
+	because the latter fonts _must_ be embedded in PDF documents.
+	If they're not present, skip the test rather than failing it.
+	* font/devpdf/tests/check-urw-foundry.sh.in: Skip test if no URW
+	fonts detected at configuration time, rather than failing it.
+	* m4/groff.m4 (GROFF_GROPDF_PROGRAM_NOTICE)
+	(GROFF_URW_FONTS_NOTICE): Drop warnings of expected test
+	failures.  The tests no longer fail in the anticipated
+	circumstances.
+
+2023-02-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[devpdf]: Generate tests from template files, so we can populate
+	the test scripts with information determined at configuration.
+	The default foundry test depends on $GHOSTSCRIPT, and the URW
+	foundry test on $urwfontsdir.
+
+	* font/devpdf/tests/check-default-foundry.sh:
+	* font/devpdf/tests/check-urw-foundry.sh: Rename these...
+	* font/devpdf/tests/check-default-foundry.sh.in:
+	* font/devpdf/tests/check-urw-foundry.sh.in: ...to these.
+
+	* font/devpdf/devpdf.am (font_devpdf_default_test)
+	(font_devpdf_urw_test): New variables store names of generated
+	test scripts.
+	(font/devpdf/tests/check-default-foundry.sh):
+	(font/devpdf/tests/check-urw-foundry.sh): New targets produce
+	test scripts from corresponding .in files.
+
+2023-02-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[devpdf]: Trivially refactor.  Rename sed-substitutum [Lat.]
+	from "@GROFF_GHOSTSCRIPT_INTERPRETERS@" to "@GHOSTSCRIPT@" for
+	clarity and brevity; this is a scalar value containing the
+	Autoconf-determined name of the Ghostscript interpreter.  It is
+	not the same as the replacement that occurs in contrib/pdfmark.
+
+	* font/devpdf/devpdf.am:
+	* font/devpdf/util/BuildFoundries.pl: Do it.
+
+2023-02-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[build]: Stop scraping output of Ghostscript executable with
+	"-h" option to attempt to find URW fonts.  Fonts that ship with
+	Ghostscript are regarded as the "default" foundry, not the URW
+	foundry (though they often ultimately originate with URW fonts).
+	They are often missing Adobe Font Metric (AFM) files, so it is
+	impossible for groff to generate font description files for them
+	at build time.
+
+	* m4/groff.m4 (GROFF_URW_FONTS_CHECK): Drop `AC_REQUIRE` on
+	`GROFF_AWK_PATH`.  Drop awk-based scraping of Ghostscript "-h"
+	output.  Annotate need for sync between this list of
+	characteristic font file names and the one in BuildFoundries.
+
+	Thanks to Deri James for the ongoing discussions.
+
+2023-02-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* configure.ac: Drop now-redundant explicit
+	`GROFF_URW_FONTS_CHECK`.  `GROFF_GROPDF_DEPENDENCIES_CHECK`
+	`AC_REQUIRE`s it as of commit ec001d2a23, 18 February.
+
+2023-02-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_URW_FONTS_CHECK): When looking for a
+	characteristic URW font by its file name, also check for
+	"URWGothic-Book" with no file extension.  Avoids false negatives
+	in URW Type 1 font detection when using Ghostscript 9.53.3.
+	Thanks to Deri James for suggesting the test procedure that
+	uncovered this flaw.
+
+2023-02-22  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* Makefile.am (uninstall_groffdirs): Remove "html.mono" and
+	"html.node" directories corresponding to HTML version of our
+	Texinfo manual.
+	* doc/doc.am (uninstall-html): Uninstall HTML version of our
+	Texinfo manual more reliably.
+
+	Fixes a regression introduced by me in commit c2698aade, 6 April
+	{my claim "we're only deleting files with this command, not
+	directories" was not correct}.
+
+2023-02-22  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[doc]: Handle output formats of our Texinfo manual more
+	consistently.
+
+	* doc/doc.am (install-doc): Add dependency on (Automake
+	standard) target 'install-dvi'.
+	(maintainer-clean-local): Remove our Texinfo manual in plain
+	text format.
+	(install-data-local): Add dependency on new target
+	'install-txt'.
+	(install-txt): Install our Texinfo manual in plain text format.
+	(uninstall-local): Add dependency on new target 'uninstall-txt'.
+	(uninstall-txt): Uninstall our Texinfo manual in plain text
+	format.
+
+	Thanks to T. Kurt Bond for noticing the discrepancy.
+
+2023-02-22  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (install-pdf-local, install-html-local): Enable
+	rules to work in out-of-tree builds.
+
+2023-02-22  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (uninstall-hook): Drop dependency on
+	"uninstall_mom"; this is not the appropriate place to declare
+	it, and "uninstall_groffdirs" already depends on it in mom's
+	Automake file.
+
+2023-02-22  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[tests]: Have more tests report output.
+
+	* src/roff/groff/tests/ab_works.sh:
+	* src/roff/groff/tests/handle_special_input_code_points.sh:
+	* src/roff/groff/tests/initialization_is_quiet.sh:

+	* src/roff/groff/tests/soquiet_works.sh:
+	* tmac/tests/an-ext_MR-works.sh:
+	* tmac/tests/an_MR-works.sh: Do it.
+
+2023-02-22  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[tests]: Prevent failures when $GROFF_ENCODING is set.
+
+	* src/roff/groff/tests/ab_works.sh:
+	* src/roff/groff/tests/handle_special_input_code_points.sh:
+	* src/roff/groff/tests/initialization_is_quiet.sh:
+	* src/roff/groff/tests/msoquiet_works.sh:

+	* tmac/tests/an-ext_MR-works.sh:
+	* tmac/tests/an_MR-works.sh:
+	* tmac/tests/an_font-remapping-does-not-affect-titles.sh: Unset
+	$GROFF_ENCODING before running test because preconv(1) confounds
+	these tests.
+
+	Thanks to Alexis for reporting this problem.
+
+2023-02-21  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[ms]: Rename test.
+
+	* tmac/tests/s_no-excess-space-around-displays.tmac: Rename...
+	* tmac/tests/s_no-excess-space-around-displays.sh: ...to this.
+	* tmac/tmac.am (tmac_TESTS): Update.
+
+2023-02-21  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[gropdf]: Revise tests to run unconditionally, rather than
+	configuring them away at build time, which can cause a
+	distribution archive to be incorrectly structured.  Update
+	configuration notices when optional dependencies are absent.
+
+	* font/devpdf/devpdf.am (font_devpdf_TESTS): Remove `USE_GROPDF`
+	and `HAVE_URW_FONTS` conditionals.
+	* m4/groff.m4 (GROFF_GROPDF_PROGRAM_NOTICE):
+	(GROFF_URW_FONTS_NOTICE): Warn reader that a gropdf test failure
+	is to be expected.
+
+	Fixes <https://savannah.gnu.org/bugs/?63824> (2/2).
+
+2023-02-21  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[grohtml]: Revise tests to check for requisite programs at test
+	time and skip if not found, rather than configuring them away at
+	build time, which can cause a distribution archive to be
+	incorrectly structured.
+
+	* m4/groff.m4: Annotate requisite program list since we're
+	violating the DRY principle.
+	* src/roff/groff/groff.am (groff_TESTS): Populate
+	unconditionally.
+
+	* src/roff/groff/tests/html_works_with_grn_and_eqn.sh:
+	* src/roff/groff/tests/smoke-test_html_device.sh: Check for
+	requisite programs and skip test if any are not found.
+
+	Fixes <https://savannah.gnu.org/bugs/?63824> (1/2).
+
+2023-02-21  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[man pages]: Define page-local `MR` fallback.
+
+	[man pages]: Provide page-local fallback definition of new `MR`
+	macro.  I didn't think I was going to have to do this, but the
+	premier site on the web for viewing Linux man pages, Michael
+	Kerrisk's man7.org, has been pulling snapshots of the pages
+	themselves without upgrading the underlying macros, and so man
+	page cross references set with `MR` are getting lost in its
+	presentations.  (I acknowledge: Ingo Schwarze warned me
+	something like this could happen.)  This definition is intended
+	as a stopgap measure only.  I want to revert this after groff
+	1.23 is released and has spread to some reasonable degree.

+2023-02-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/tests/an_TS-do-not-keep-tables-when-cR-set.sh: Improve
+	portability of script by using shell constructs instead of the
+	nonstandard GNU coreutils 'seq' utility.  Resolves test failure
+	on Solaris 10.
+	* HACKING: Document this problem.
+
+2023-02-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_MAKE_DEFINES_RM): Test the make(1) in the
+	environment variable $MAKE if defined, not a literal "make".
+	Required on (some) Solaris 10 configurations where traditional
+	make(1) is not installed but GNU make is installed as "gmake".
+
+2023-02-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/tests/latin2_works.sh: Fix missing backslash in printf.
+	Solaris printf(1) was sensitive to this error; macOS and GNU
+	printf were not.  Fixes a test failure on Solaris 11.
+
+2023-02-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/roff/groff/tests/regression_savannah_58153.sh: Improve
+	portability.  Avoid the unpredictability of implementations when
+	putting backslashes inside a groff-piped printf shell command
+	inside a here document inside a command substitution by changing
+	the groff escape character to something meaningless to the shell
+	and to printf ('@').  Fixes a test failure on Solaris 11.
+
+2023-02-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* font/devpdf/Foundry.in: Recognize URW foundry replacements for
+	Helvetica Bold-Oblique and Helvetica Oblique under the file
+	names "NimbusSans-BoldItalic.t1" and "NimbusSans-Italic.t1",
+	respectively.
+
+2023-02-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (uninstall-pdf): Clean more fastidiously; try to
+	remove the configured `pdfdocdir` in the event it is empty, but
+	do not fail if it isn't.  (It can be a directory shared with
+	other groff components; we don't know in what order the
+	uninstall targets will serialize, but the last one run should
+	succeed.)

+	[build]: Detangle "pdfroff" and "gropdf" configuration (2/2).
+
+	* m4/groff.m4: Give pdfroff its own Autoconf macros to handle
+	dependency checking, build objectives, and user notice.
+	(GROFF_PDFROFF_DEPENDENCIES_CHECK): New macro requires
+	`GROFF_AWK_PATH` and `GROFF_GHOSTSCRIPT_PATH`, determines
+	whether pdfroff can be used at build time, and (if not)
+	constructs part of message to be shown to user explaining why.
+	(GROFF_PDFROFF_PROGRAM_NOTICE): New macro requires
+	`GROFF_PDFROFF_DEPENDENCIES_CHECK` and emits message if needed.
+	(GROFF_GHOSTSCRIPT_AVAILABILITY_NOTICE): Drop mention of impact
+	on pdfroff since its dedicated notice covers this now.
+	* configure.ac: Call the new macros at appropriate times.
+	Produce a new Automake macro, `USE_PDFROFF`, to replace
+	inapposite use of `USE_GROPDF` in pdfmark.am.
+	* contrib/pdfmark/pdfmark.am: Use `USE_PDFROFF` instead of
+	`USE_GROPDF`.
+
+2023-02-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[build]: Detangle "pdfroff" and "gropdf" configuration (1/2).
+
+	* m4/groff.m4 (GROFF_GROPDF_DEPENDENCIES_CHECK): Add
+	`AC_REQUIRE`ment on `GROFF_URW_FONTS_CHECK`.  Per discussion
+	with Deri James, if _either_ Ghostscript or the URW fonts are
+	avilable, gropdf will be fully functional, consequent to commit
+	d5515, 22 June.  Drop dependency on awk; it is used only at
+	configuration time (in an Autoconf macro) and since Savannah
+	#62775 was resolved (19 September), it has not been strictly
+	necessary.  (It is useful for searching more locations for URW
+	fonts, but several others are searched even if it is absent.)
+	Stop populating notice text here, instead moving it...
+	(GROFF_GROPDF_PROGRAM_NOTICE): ...here, since it no longer needs
+	to be dynamically constructed.
+
+	Continues <https://savannah.gnu.org/bugs/?63808>.  Thanks to
+	Deri James for the continued discussion.
+
+2023-02-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[build]: Rename `GROFF_CHECK_GROPDF_PROGRAMS` macro to
+	`GROFF_GROPDF_DEPENDENCIES_CHECK` to generalize for greater
+	accuracy in forthcoming change.
+
+	* configure.ac:
+	* m4/groff.m4: Do it.
+
+2023-02-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[gropdf]: Don't run automated tests if 'gropdf' will be
+	operating with reduced function.  If neither Ghostscript nor the
+	URW fonts are available at configuration time, there is no point
+	testing for successful build-time population of the font
+	descriptions for the default and URW foundries.
+
+	* font/devpdf/devpdf.am (font_devpdf_TESTS) [USE_GROPDF]: Run
+	"check-default-foundry" only if gropdf is fully functional.
+	(font_devpdf_TESTS) [USE_GROPDF && HAVE_URW_FONTS]: Run
+	"check-urw-foundry" only if the URW fonts were found.
+
+	Continues <https://savannah.gnu.org/bugs/?63808>.  Thanks to
+	Deri James for the continued discussion.
+
+2023-02-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[gropdf]: Rename tests to more accurately characterize their
+	purpose.
+
+	* font/devpdf/tests/basic-fonts-present.sh:
+	* font/devpdf/tests/urw-fonts-present.sh: Rename these...
+	* font/devpdf/tests/check-default-foundry.sh:
+	* font/devpdf/tests/check-urw-foundry.sh: ...to these.
+	* font/devpdf/devpdf.am (font_devpdf_TESTS): Reflect rename.
+
+2023-02-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[gropdf]: Revise tests to be foundry-focussed.
+
+	* font/devpdf/tests/basic-fonts-present.sh: Stop trying to match
+	font descriptions in the "devps" directory with ones in
+	"devpdf"; instead, test whether "BuildFoundries" did its job.
+	Test for font descriptions corresponding to the full 35
+	PostScript Level 2 font repertoire, plus groff's "EURO".
+	* font/devpdf/tests/urw-fonts-present.sh: Drop stale comment and
+	rename variable for better parallelism with the other test
+	above.
+
+	Continues <https://savannah.gnu.org/bugs/?63808>.  Thanks to

+
+2023-02-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[man]: Tweak fix to Savannah #63768.
+
+	* tmac/an.tmac (MR): Ensure `an*url` always has a value,
+	defaulting to "format 1" (man:page(section)).  Resequence the
+	macOS URL formats to sort the contemporary one before the
+	others.
+	* tmac/man.local: Reflect resequencing of integer assignments to
+	formats.  Clarify historicity of annotations.
+
+	Continues <https://savannah.gnu.org/bugs/?63768>.  Thanks to
+	John Gardner for further discussion.
+
+2023-02-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[ms]: Port a test to Solaris 11 sed.
+
+	* tmac/tests/s_TC-works-with-percent-in-custom-titles.sh: Put
+	newlines after opening braces in sed scripts.  macOS and GNU sed
+	tolerate their absence, but this sed does not.
+	* HACKING: Document this problem.
+
+2023-02-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/roff/groff/groff.am (groff_TESTS) [!USE_GROHTML]: Don't
+	test the 'grohtml' driver if we know it won't work.
+
+2023-02-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/roff/groff/tests/\
+	device_control_escapes_express_basic_latin.sh: Use printf(1),
+	which is often a shell built-in command, more consistently.
+	Double backslashes intended as literals in the format string,
+	and single-quote format strings using them.  Fixes test failure
+	seen on Solaris 11 with GNU Bash 4.4 and ksh 93u+ (2012-08-01).
+
+2023-02-15  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/tests/an_use-input-traps-correctly.sh: Explicitly test
+	`SM` and `SB` with 'ps' output device.  If one set
+	GROFF_TYPESETTER=utf8 in the test environment, these test cases
+	would fail.  Thanks to John Gardner for the report.
+
+2023-02-15  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* configure.ac: Add Automake conditional, `HAVE_GHOSTSCRIPT`, so
+	that we can populate the list of PDF device font tests
+	dynamically.  Call new macro
+	`GROFF_GHOSTSCRIPT_AVAILABILITY_NOTICE`.  Call
+	`GROFF_GHOSTSCRIPT_VERSION_NOTICE` after it, but before
+	`GROFF_URW_FONTS_NOTICE`.
+	* m4/groff.m4 (GROFF_AWK_NOTICE): New macro produces warning if
+	no awk could be found.  This reduces gropdf functionality, but
+	so do missing URW fonts, so we report this problem separately.
+	Report the names under which we sought it, since there's a
+	configure script option for that.
+	(GROFF_GHOSTSCRIPT_AVAILABILITY_NOTICE): New macro explains
+	consequences of missing optional dependency on Ghostscript
+	program: reduced grohtml functionality, nonfunctional pdfroff.
+	Report the names under which we sought it, since there's a
+	configure script option for that.
+	(GROFF_CHECK_GROPDF_PROGRAMS): Better characterize gropdf's
+	reduced function, pointing out the ways in which it would be
+	more useful if the dependencies were met.  Also simplify the
+	computational grammar.
+	(GROFF_URW_FONTS_NOTICE): Identify 'U' as the foundry name
+	gropdf uses for the URW fonts.  Confirm continuing availability
+	of most recent URW fonts release; bump date.
+	* font/devpdf/devpdf.am: Test availability of "basic" (PDF base
+	14) fonts (plus groff's "EURO") if either Ghostscript or URW
+	fonts are available.  Test availability of URW fonts (35) only
+	if Ghostscript _and_ the URW fonts were found at configuration
+	time.
+
+	Fixes <https://savannah.gnu.org/bugs/?63808>.  Thanks to Deri
+	James for the report and extremely helpful pseudocode.
+
+2023-02-15  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_GHOSTSCRIPT_VERSION_CHECK,
+	GROFF_URW_FONTS_NOTICE): Add macro dependency on
+	`GROFF_GHOSTSCRIPT_PATH`, which should have been there already.
+	(GROFF_GROHTML_PROGRAM_NOTICE): Add macro dependency on
+	`GROFF_CHECK_GROHTML_PROGRAMS`, which should have been there
+	already.
+
+	(GROFF_CHECK_GROHTML_PROGRAMS, GROFF_PNMTOOLS_CAN_BE_QUIET):
+	Move `AC_REQUIRE` expansions to precede shell variable
+	assignments (after checking that the required macros don't
+	clobber the assignments we're making).
+
+2023-02-15  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* font/devpdf/tests/basic-fonts-present.sh: Revise test again,
+	per feedback from Deri James.  Even without Ghostscript or URW
+	fonts available, gropdf can generate valid PDF documents; it
+	simply can't embed fonts in general (without further
+	arrangements made on the host system), which means it is
+	restricted to the PDF base 14 fonts.  That's enough for many
+	purposes, including generating our compiled man pages document
+	{with minor degradations to the typeface lists in gropdf(1) and
+	grops(1)}.  Drop the 'gs' command check, which also didn't check
+	for the name of the Ghostscript interpreter determined by the
+	"configure" script.  Replace dynamically generated font list
+	with a static one (the base 14 fonts plus groff's EURO).
+
+2023-02-13  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* font/devpdf/tests/basic-fonts-present.sh: Revise test.
+	Improve explanation of why we're looking for the gs(1) command
+	in a font availability test.  Prefix diagnostic output with name
+	of test script.  Perform a search for the 'ps' device font
+	descriptions that will work in more build scenarios (i.e., don't
+	assume an out-of-tree build taking place in an immediate
+	subdirectory of the source).  Distinguish failure to find the
+	font descriptions from a failure to locate the 'gs' command,
+	skipping the test in both scenarios.  Reduce noise in output.
+	* m4/groff.m4 (GROFF_CHECK_GROPDF_PROGRAMS): Revise warning
+	issued when awk and Ghostscript are unavailable; gropdf will not
+	be completely inoperative.  Characterize its reduced function.
+
+	Thanks to Deri James in <https://lists.gnu.org/archive/html/\
+	groff-commit/2023-02/msg00089.html> for prompting me to take a
+	another look at this.

+
+	* tmac/tests/latin2_works.sh:
+	* tmac/tests/latin5_works.sh:
+	* tmac/tests/latin9_works.sh: Port to work around macOS's
+	apparently POSIX non-conforming 'od' command.  Use single-byte
+	octal output format instead of "character", and update test
+	expectations accordingly.  Apparently gratuitously, macOS also
+	puts more spaces after the octal address field when using this
+	output format.
+	* HACKING: Document, and elaborate upon, this problem.
+
+2023-02-13  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[mdoc]: Port a test to work with macOS sed.
+
+	* tmac/tests/doc_heading-font-remapping-works.sh: Put semicolons
+	between commands and closing braces in sed script.  Put each of
+	multiple closing braces on a separate input line, because macOS
+	doesn't accept them otherwise.  Resolves test failure observed
+	on macOS.
+	* HACKING: Document the closing brace sequence problem.

+2023-02-13  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[man]: Port a test to work with macOS sed.
+
+	* tmac/tests/an_TS-adds-no-vertical-space.sh: Put semicolons
+	between commands and closing braces in sed script.  Separate
+	command stream into multiple '-e' expressions, breaking them
+	after branch and label commands.  Resolves test failure observed
+	on macOS.
+	* HACKING: Document the above problems.

+

+	some_escapes_accept_newline_delimiters.sh: Weaken regexes in two
+	test cases to accommodate excessive output from macOS's 'od'
+	command.  Resolves test failure seen on macOS.
+	* HACKING: Add section "Writing Tests" and document the above
+	since this is the second time I've cracked my shin on this.
+
+2023-02-13  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* font/devpdf/tests/basic-fonts-present.sh: Skip test if 'gs'
+	command not available.  The test is to ensure that gropdf will
+	produce sound documents using the base fonts from PostScript,
+	but since gropdf requires Ghostscript to do this (as noted in
+	our "./configure" messages), it makes no sense to validate font
+	availability if the program is absent.  Resolves test failure
+	seen on macOS with minimal dependencies installed.

+
+	* tmac/an.tmac: Add internal register `an*MR-URL-format` to

+	are three known on macOS, and one used everywhere else.
+	* tmac/man.local: Document this feature so macOS users can enjoy

+
+	Switch to using system's assert.h header file.  It is futile to
+	attempt to preserve compatibility with ISO C90 systems by
+	providing a bespoke predicate-reporting assert() (a C99 feature)

+	that `static_assert` remains defined so that gnulib can use it.

+
+2023-02-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[tbl]: Fix bugs using boxes or vertical rules at table edges on
+	nroff devices, particularly when combined with region or column
+	expansion.
+
+	* src/preproc/tbl/table.h (class table): Add `GAP_EXPAND`
+	enumeration constant.  James Clark seems to have designed GNU
+	tbl carefully to avoid distinguishing region expansion from
+	column expansion in a categorical way, but I needed a way for
+	formatting-time logic to know which was in use.  (Column
+	expansion, the "x" modifier, expands columns--i.e., text.
+	Region expansion expands [or compresses] the _gaps_ between
+	columns.)
+	* src/preproc/tbl/main.cpp (process_options): Set `GAP_EXPAND`
+	flag in table if "expand" region option seen.
+	* src/preproc/tbl/table.cpp: Add new macro `LEFTOVER_FACTOR_REG`
+	to name a new roff register for the remainder of gap-expansion
+	space when the amount of space available for expansion is
+	divided by the number of gaps.
+	(table::compute_overall_width): If _not_ expanding a table in
+	either respect and in nroff mode, reduce line length by 1n for
+	each of any left and right border (because the vertical lines
+	eat character cells).  This prevents bordered or boxed tables
+	from being overset even when they use neither expansion feature.
+	(table::compute_separation_factor): If gap-expanding a table,
+	store any remainder from the division used to compute the
+	separation factor into the new `LEFTOVER_FACTOR_REG`.
+	(table::compute_column_positions): Insert that remainder into
+	the gap before the last (rightmost) column of the table.  This
+	_could_ be done more elegantly by spreading each en in a
+	symmetric way across a subset of the gaps.  (It is necessarily a
+	subset by the pigeonhole principle.)  But it didn't seem worth
+	the effort for a feature (region expansion) that few users
+	employ.  (Usually what you want is the "x" column modifier.)

+	line length), but might not (yet) fully expand to that length on
+	low-resolution devices due to integer roundoff.

+
+	* tmac/an-ext.tmac: Move the saving of the hyphenation mode from
+	the "top level" to...
+	(mY): ...this new macro.
+	(SY, mQ, MR): Call `mY` before disabling hyphenation.
+
+	Problem introduced by me in commit 096c2f0567, 16 February.
+	"an-ext.tmac" gets sourced by "an.tmac" before any
+	command-line setting of the `HY` register is handled, so (for
+	groff) the stored hyphenation mode was the default for the
+	language, not reflecting user disablement.  The synopsis macros,
+	which do not have an alternate implementation in "an.tmac" for
+	leverage of groff features, were causing hyphenation to be
+	resurrected (after `YS`) even if the user had disabled it.
+	Saving the hyphenation mode anew upon entry to these macros is
+	arguably inefficient, but it is more correct since a man page
+	could conceivably manipulate the automatic hyphenation mode
+	{even if that's not recommended outside of tbl(1) text blocks}.
+
+2023-01-08  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[man]: Add regression test for hyphenation getting wrongly

+2023-01-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/mdoc/doc-common (Sh, Ss): Narrow scope of font remappings
+	lexically and restrict remapping to the heading font family (if
+	any) to avoid undesired remapping of fonts in page headers if,
+	say, a (sub)section heading begins just prior to a page
+	break--which is ugly anyway and should be avoided, but the

+	possibly exits with status 77 to skip some checks.  Within trap
+	handler, mask trapped signals while running handler.
+	(cleanup): Reset trap dispositions to default after removing

+
+	* tmac/papersize.tmac: Improve integration with mm(7) macro
+	package.  If a paper format has been selected, set `W` register
+	to new line length (if not already set on command line).
+	Similarly, set `O` register to 1 inch for the symmetric
+	horizontal margins otherwise assumed by this macro file.  This
+	means that "groff -mm" and "groff -dpaper=letter -mm" are _not_
+	synonymous (when groff is configured to use U.S. letter as the
+	default paper format), because groff mm(7) uses a page offset of
+	0.963 inches on typesetters for compatibility with DWB mm.

+2022-11-11  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an-ext.tmac (UR, MT): Fix problem with incorrect line
+	lengths and occasional "can't adjust" warnings when using
+	hyperlinks.  Reduce the line length within the diversion by the
+	amount of indentation used in the context.  Without this, lines
+	were getting set too short.  (You might think they'd be too
+	long, but when creating a new environment, the _formatter's_

+	(devpdffont_DATA): Populate using `DEFAULT_BASE35_FONTS`.
+	(URW_BASE35_FONTS): Add new macro, empty if [!HAVE_URW_FONTS];
+	and [HAVE_URW_FONTS] otherwise naming the `U` foundry font
+	description counterparts of the `DEFAULT_BASE35_FONTS`.
+	(devpdffont_DATA): Append `URW_BASE35_FONTS`.
+	($(DEFAULT_BASE35_FONTS) $(URW_BASE35_FONTS)): Assert dependency
+	on "font/devpdf/download".  This isn't literally true, but
+	BuildFoundries generates all of these together, so if the
+	"font/devpdf/download" target rule runs successfully, the font
+	description files named in these macro expansions will be
+	generated too.

+
+	* src/utils/afmtodit/afmtodit.pl: Add new command-line option to
+	specify the generated font description's "spacewidth" parameter;
+	in commit bf7f6862c3, 2021-09-24, I made libgroff complain if
+	this directive is missing (since any font, even a "special" one,
+	can be selected as current and the formatter's behavior when
+	encountering an input space should be well-defined under that
+	circumstance).  Adding this option enables a well-formed font
+	description to be produced.

+2022-11-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* font/devpdf/util/BuildFoundries.pl (LoadFoundry): Stop

+	from font path elements.
+
+2022-11-08  G. Branden Robinson <g.branden.robinson@gmail.com>

+
+2022-11-07  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/pic/pic.ypp: Slightly refactor.  Rename parameter

+	clear.
+	(format_number, do_sprintf): Reorder null pointer equality
+	comparisons to avoid inadvertent lvalue assignment.
+	(do_sprintf): Declare lists of valid format conversion
+	specifiers and modifiers explicitly instead of as happenstance
+	literals.  Recast diagnostic messages to refer to "invalid", not
+	"bad" input; refer to input keyword correctly as "sprintf" (not
+	"snprintf"); and report the identity of the invalid conversion
+	specifier we reject.

+
+	* src/devices/gropdf/gropdf.pl: Test if path in the "download"

+
+2022-11-05  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[mdoc]: Set page topic in roman in "Name" section.
+
+	* tmac/doc.tmac (Nm): If in the "Name" section of the page, set
+	argument(s) with the `No` (normal formatting) macro instead of
+	handling them...normally.  Since `Nm`'s usual behavior is to set
+	the next argument in boldface, in this circumstance it is set in
+	roman.  Aligns page rendering with man(7) and fixes a bug
+	documented in the 4.3BSD-Reno mdoc.samples(7) page (1990-06-22),
+	upon which the groff_mdoc(7) page is based.
+	* tmac/groff_mdoc.7.man (Bugs): De-document bug.

+
+2022-11-05  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/mdoc/doc-common: Add internal register
+	`doc-in-name-section` to keep track of whether a macro is called

+	(Sh): Canonicalize capitalization of section heading sooner.

+

+	`Fl` ("flag") macros on typesetters.
+
+	* tmac/mdoc/doc-ditroff (doc-Cm-font, doc-Fl-Font): Switch to
+	Courier roman from Courier bold.  This congrues better with
+	other `Li` literals, which were not in boldface.
+
+2022-11-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/mdoc/doc-nroff (doc-Li-Font): Switch from roman to bold.
+	On typesetters, the use of Courier (roman) plainly distinguishes
+	unquoted literals from their context.  On terminals there was no
+	such visible distinction.  Fortunately, in groff_mdoc(7) itself,
+	this does not result in a blinding blitz of boldface because the
+	`Ql` (quoted literal) macro is so often used, and it maintains
+	the roman style.  This change further aligns groff mdoc(7) with
+	groff man(7) style conventions.  (Also see how we handle
+	literals for typesetters and terminals in the "ms.ms" document.)

+	number, e.g., "troff(1)"; `doc-abbv` stores the its potentially

+	(doc-footer): Use `doc-xref` as above.  Stop setting the `Os`
+	and `Dd` parameters in the ("semantic"?) font used for the
+	page's section number (probably unnoticed all these years
+	because the font used to render that was (Times) roman).

+
+	* tmac/mdoc/doc-common (Ss): Indent entire subsection heading by
+	3 ens, even if it breaks across output lines.  (Change and
+	restore indentation explicitly instead of using a temporary
+	indent to achieve this.  Also indent absolutely by 3n instead of
+	retreating by one quarter inch.)

+	(main): Exit with `EXIT_SUCCESS` status when writing version or

+	error.  Use `fprintf()` and `strerror()` to construct error
+	message when dying due to inability to open input file instead

+
+	* tmac/fallbacks.tmac: Define fallback characters for many code
+	points from the Unicode General Punctuation Block.  This is to
+	ease migration from other documentation formats; in many cases
+	there are more idiomatic *roff ways of getting results that
+	typeset better and are amenable to fine tuning.  For instance,
+	Unicode defines spaces and dashes of various discrete widths;
+	when typesetting with *roff, you can have a space or dash (among
+	other things) of any length achievable by the output device.
+	* tmac/ps.tmac: Migrate non-breaking hyphen fallback character
+	definition from here to the foregoing.

+	[mdoc]: Fix code style nit.  Rename `doc-arg-limit` to
+	`doc-arg-count`.  This register doesn't track any sort of limit

+
+	[docs]: Fix errors in documentation regarding which escape

+	inaccuracies.
+
+	* doc/groff.texi (Escape Sequences): Cover general cases before
+	exceptional ones.  Leaders can be used as argument delimiters.
+	Call out letters and numerals as (usually) usable as well.
+	Correct an almost completely inaccurate list of escape sequences
+	that accept a newline as an argument delimiter: \A, \b, \o, \w,
+	\X, and \Z do; \B does not.  Correct example of use of newline
+	as delimiter with \o escape sequence.  Stop referring to the
+	decimal point as an "operator".  Drop "newline" from a list of
+	prohibited delimiters by several escape sequences since it has
+	already been discussed.
+
+	* man/groff.7.man (Escape sequences): Replace weaksauce cross
+	reference to our Texinfo manual with a proper discussion of
+	acceptable delimiters in escape sequences, synced with the
+	foregoing change.  Stop using quotation marks around escape
+	sequences, except for "\ " which obviously needs it.

+
+	* tmac/mdoc/doc-nroff: Map monospaced fonts (CR, CB, CI, CBI) to

+	[mdoc]: Stop prefixing center header with name of operating

+	operating system.  Bad idea.  Further, the argument to the `Os`
+	call, if any, or a default, is always disclosed in the left
+	footer.
+
+	* tmac/mdoc/doc-common: Do it.
+	(Dt): Initialize `doc-volume` as empty and annotate it;

+
+	[mdoc]: Align trap management more closely with man(7).
+
+	* tmac/mdoc/doc-common: Call new macro (see below)
+	`doc-set-up-continuous-rendering` when initializing, if that
+	mode is configured.
+	(doc-ne): New macro replaces `ne` request
+	in continuous rendering mode.  It extends the page length by the
+	amount in the argument or by 1v if none given.
+	(doc-bp): New macro replaces `bp` request in continuous
+	rendering mode, setting the page length to the vertical drawing
+	position.
+	(doc-set-up-continuous-rendering): New macro renames requests to
+	emplace the foregoing.
+	(Dd): Interpret this macro call strictly as starting a new
+	mdoc(7) document.  (andoc.tmac already makes this assumption,
+	and has for over 20 years.  groff_mdoc(7) and mandoc_mdoc(7)
+	also prescribe the sequence `Dd`, `Dt`, `Os`.)  We require this
+	invariant even more rigidly now because it's the only way we can
+	be sure that we can process multiple documents while rendering
+	headers and footers with information corresponding to the
+	appropriate document.  (man(7)'s `TH` has an advantage here in
+	that calling it is "atomic": from its arguments alone you can
+	obtain everything you need to know to format the header and
+	footer.  In mdoc(7), permuting the initialization macro order
+	reliably produces chaos.)  Break the page (if necessary)
+	_before_ processing any arguments (instead of after), to flush
+	the previous page's footer.  Stop calling `doc-set-up-titles`
+	here; we don't have enough information to do that yet.  Also
+	stop writing the PDF bookmark here, because `doc-document-title`
+	and `doc-section` will not reflect the new page content yet.
+	(Os): Once the `doc-operating-system` string content has been
+	determined, call `doc-set-up-titles`, write the PDF bookmark for
+	the page, and call `doc-header`, causing the page header to be
+	formatted.  These changes further imply a stronger requirement
+	on initialization macro ordering being canonical.

+
+2022-09-07  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[mdoc]: Trivially refactor.  Relocate string and macro

+	Relocate conditional branches to front-load early returns as

+
+	Bug #62934 - after glyph remapped mark it as used
+
+	When many glyphs are remapped from code points above 255
+	such as writing documents in cyrillic with the U-TR fonts,
+	gropdf starts reusing code points in the range 128-255.
+	If subsequently one of those code points is actually required,
+	such as \(em (code 138), and it has been replaced by a
+	cyrillic, then it needs to be mapped to another free code.
+
+	To determine if a particular code point is free each glyph
+	has a USED flag. The bug was caused because after remapping
+	\(em to the next free glyph the USED flag was not set. So the
+	next new cyrillic character to be entered was given the same
+	code point as had been allocated to \(em.
+
+	* src/devices/gropdf/gropdf.pl: Set the USED flag on remapped
+	glyphs.
+
+	Fixes <https://savannah.gnu.org/bugs/?62934>.

+	With a large font if 2 characters above the 255 code

+
+	* src/devices/gropdf/gropdf.pl: Instead of duplicating a pointer
+	to the font metadata, duplicate the data itself. Then, if the
+	glyph is remapped to a code point under 256, the metadata is

+
+2022-06-27  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/html/pre-html.cpp: Refactor.  Drop unnecessary
+	prototype for static function.  Use idiomatic C++98 null pointer
+	constant.  Annotate it as null pointer to ease any future
+	migration to ISO C++11.  Boolify.  Use C++98 bool data type
+	instead of preprocessor macros `TRUE` and `FALSE`.  Demote some
+	global Boolean variables from `int` to `bool` and rename some to
+	be more clear: `show_progress` -> `want_progress_report`;
+	`debugging`; `eqn_flag` -> `need_eqn`.
+	(make_message): Rename this...
+	(make_string): ...to this.  Align more closely with contemporary
+	version of example from Linux man-pages printf(3) page.  Use
+	`vsnprintf()` to determine size of memory buffer needed prior to
+	allocation instead of iteratively growing it until it is large
+	enough.  Always die if `vsnprintf()` fails: this function now
+	always returns a valid pointer if it returns at all.
+	(makeFileName, setupAntiAlias, imageList::createPage,
+	imageList::createImage): Update call sites to use
+	`make_string()`.
+	(char_buffer::can_see): Demote return type from `int` to `bool`.
+	(char_buffer::skip_spaces): Drop unused member function.
+	(char_buffer::read_file, makeTempFiles): Demote return type from
+	`int` to `void`.  Stop returning after calling functions that
+	don't return.
+	(char_buffer::read_file): Call `sys_fatal()` if `fread()`
+	returns an error, similarly to other calls into the standard C
+	library that this file makes.  Improve check for error from
+	`fread()` by not regarding a return value of zero when the
+	end-of-file indicator is set as an error condition.
+	(makeFileName, checkImageDir, char_buffer::run_output_filter,
+	scanArguments): Call `fatal()` instead of `error()` and then
+	`exit(1)`.
+	(makeFileName, scanArguments): Dismiss Shlemiel the Painter:
+	save return value of `strlen()` and call `strcpy()` multiple
+	times instead of mixing `strcpy()` and `strcat()`; the latter
+	approach rescans the string unnecessarily.
+	(char_buffer::run_output_filter): Stop passing unnecessary null
+	pointer argument to diagnostic message functions.  Stop calling
+	`fflush()` after libgroff diagnostic function, which always
+	{ultimately} flushes the standard error stream itself.
+	(makeTempFiles, do_file, main): Boolify.
+	(makeTempFiles, do_file): Reorder null pointer equality
+	comparisons to avoid inadvertent lvalue assignment.
+	(scanArguments, main): Use `EXIT_SUCCESS` and `EXIT_FAILURE`
+	constants from C library instead of integer literals for exit
+	status.
+	(do_file): Demote return type from `int` to `bool`.  Return
+	Boolean literals.  Drop conditional with empty consequent.
+	(main): Declare local variables closer to the points of use.
+	Stop trying to be a register allocator: stop reusing loop index
+	variable `i` as integer storage for another (albeit related)
+	purpose; introduce `operand_index` instead.  Clarify logic by
+	splitting combined initialization and comparison operations, and
+	by testing function return value directly instead of storing it
+	in a pointless temporary.  Use `EXIT_SUCCESS` and `EXIT_FAILURE`
+	constants from C library instead of integer literals for exit
+	status.

+	(char_buffer::run_output_filter, main): Rename local variable
+	`status` to `wstatus` to recognize distinction between exit
+	status (a 7-bit quantity) and wait status (a wider type).
+	(main): Issue fatal diagnostic if child process exited with
+	nonzero status.  Since the child's output to the standard error
+	stream is lost, advise re-running with different output driver
+	to see them.  This unhappy shortcoming is filed as Savannah
+	#62673.  Explicitly return zero otherwise.

+	That is, demote its type from `int` to `bool`, invert its sense,
+	and rename it since it affects warning, not error, diagnostics.

+
+2022-06-22  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/roff/groff/groff.cpp (handle_unknown_desc_command):

+
+	* tmac/an-ext.tmac (UR, MT): Fix problem with hyphenation
+	occurring before the end of the line when the line length was
+	not the device default (common for man pages at the terminal)
+	and hyperlinks were enabled.  The issue is that the new
+	environment we created inherits the default environment's line
+	length (its state at troff initialization, prior to macro
+	package loading and configuration).  This latent issue was
+	exposed by post-groff 1.22.4 changes to enable the hyphenation
+	of link text and add the hyperlink feature.  Fix it by copying
+	the line length at the time the macro is called, which is
+	necessarily after man(7) sets up the line length, to the new
+	environment.

+2022-06-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/roff/groff/groff.cpp: Refactor to be more meticulous with

+	returned by `putenv()`; once used, they need to remain valid for
+	the lifetime of the program.
+	(xstrdup): Add `strdup()` wrapper: dies if `strdup()` fails.

+	* man/roff.7.man (Concepts): Do it.  "Spaces" is a now a term
+	with a much more restricted usage.  Emphasize the input context,
+	now explicitly identified as plain text files with Unix line
+	endings.
+
+	Fixes (one hopes) <https://savannah.gnu.org/bugs/?62593>.
+	Thanks to Ingo Schwarze for the report and Dave Kemper for the

+
+	[gropdf]: Changes to BuildFoundries.
+
+	* font/devpdf/util/BuildFoundries.pl: Collect search paths into
+	an array rather than a colon delimited string, this allows
+	the @PATH_SEPARATOR@ character (':' or ';') to be used to
+	delimit paths yielded by the command 'gs -h' but still use ':'
+	to delimit paths in the Foundry file. This means the same
+	Foundry file can be used on all systems.
+
+	* font/devpdf/Foundry.in: Add more likely paths to find the URW
+	fonts.
+
+2022-06-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[build]: Weaken dependency on TeX, instead using it (to generate
+	the DVI and PDF forms of our Texinfo manual) only if it is
+	available.
+
+	* m4/groff.m4 (GROFF_USE_TEX_CHECK): Check for presence of 'tex'
+	executable in path.  Set shell variable `groff_use_tex` to "yes"
+	if present, and "no" otherwise.  This check runs only if the
+	'makeinfo' and 'texi2dvi' version checks have already passed.
+
+	* configure.ac: Run the new check.  Set Automake conditional
+	`USE_TEX` only if shell variable `groff_use_tex` is "yes".
+	Report whether "groff.dvi" and "groff.pdf" are (re-)buildable.
+
+	* doc/doc.am: Parameterize names of groff.{dvi,pdf} targets as
+	Make macros `GROFF_DVI` and `GROFF_PDF`.  Define them only if
+	`USE_TEX`.  Do _not_ update `EXTRA_DIST` macro; leave the
+	literal file names there because we require that distribution
+	archives contain these files.
+	(.texi.dvi, .texi.pdf): Update suffix rules to check `USE_TEX`
+	and fail, complaining of missing 'tex' program, if these targets
+	are attempted without it being true.  Only manually specifying
+	the file names as targets to 'make' or attempting to generate a
+	distribution archive without TeX present should cause these
+	errors.
+
+	* INSTALL.REPO: Update dependency information.
+
+	Fixes <https://savannah.gnu.org/bugs/?62592>.  Thanks to Deri
+	James for the report.
+
+2022-06-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (.texi.dvi, .texi.pdf, $(DOC_GNU_EPS)): Quote names
+	of programs when aborting because they're missing.
+
+2022-06-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_PROG_MAKEINFO, GROFF_PROG_TEXI2DVI):
+	Largely revert commit d5013ededc, 21 May: run checks for
+	'makeinfo' and 'texi2dvi' programs regardless of presence of
+	".tarball-version" file.  Their presence is a necessary (but not
+	sufficient) condition for refresh of formatted forms of our
+	Texinfo manual if the source is modified.
+
+	Begins addressing <https://savannah.gnu.org/bugs/?62592>.
+
+2022-06-08  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[build]: Rename some groff Autoconf macros to better match
+	Autoconf's own naming conventions.
+
+	* m4/groff.m4 (GROFF_MAKEINFO): Rename to...
+	(GROFF_PROG_MAKEINFO): ...this.
+	(GROFF_TEXI2DVI): Rename to...
+	(GROFF_PROG_TEXI2DVI): ...this.
+
+	* configure.ac:
+	* m4/groff.m4 (GROFF_TEXI2DVI): Update call sites.
+
+2022-06-07  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an.tmac (SH, SS, B, I, SM, SB): Set input trap with `it`
+	instead of `itc` for better Unix Version 7 man(7) compatibility.
+
+	Fixes <https://savannah.gnu.org/bugs/?51468>.  Also see
+	discussion at
+	https://lists.gnu.org/archive/html/groff/2022-06/msg00020.html
+	et sequentia (amid a vigorous bikeshedding of `\&`'s name).
+
+2022-06-07  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[man]: Regression-test use of input traps.
+
+	* tmac/tests/an_use-input-traps-correctly.sh: Do it.
+	* tmac/tmac.am (tmac_TESTS): Run test.
+
+2022-06-06  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/devices/gropdf/gropdf.pl (LoadDesc): Validate device
+	description file for essential directives and acceptable values
+	as grops(1) does.
+
+2022-06-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[troff, grohtml, grops, grotty]: Update wording of diagnostic
+	messages to refer to "motion quantum" rather than "resolution"
+	where appropriate.
+
+	* src/devices/grohtml/post-html.cpp
+	(html_printer::html_printer):
+	* src/devices/grops/ps.cpp (ps_printer::ps_printer):
+	* src/devices/grotty/tty.cpp (tty_printer::set_char)
+	(tty_printer::add_char, tty_printer::end_page):
+	* src/roff/troff/env.cpp (line_length, title_length): Do it.
+
+2022-06-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/devices/gropdf/gropdf.pl: Do more "DESC" file validation.
+	(LoadDesc): Bomb out gracefully if any of "unitwidth", "res", or
+	"sizescale" missing from "DESC" file.  This prevents Perl
+	warnings about use of uninitialized values, and undoubtedly
+	mangled output.
+
+2022-06-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/devices/gropdf/gropdf.pl: Revise diagnostic message
+	handling.
+	(top level): Add new scalar `progname` to house executable name.
+	(Msg): Output messages in format recommended by GNU Coding
+	Standards manual.  Identify who's talking (Savannah #52463).
+	Rename `lev` scalar to `fatal` since it is used only as a
+	Boolean for immediately exiting with failure status.  Report
+	diagnostic severity as part of message.
+	(Warn, Die): Add new subroutines through which all diagnostics
+	are now emitted.
+	(top level): Migrate a use of Perl `die` builtin to our `Die`.
+	(top level, ToPoints, LoadDownload, LoadDesc, do_x, GetPoints,
+	LoadSWF, LoadPDF, LoadStream, BuildStream, ParsePDFHash,
+	LoadFont, GetType1, GetChunk, RemapChr, do_N): Migrate `Msg(0,
+	...)` calls to `Warn` and `Msg(1, ...)` to `Die`.  Begin
+	messages in lowercase (GNU Coding Standards).  Recast a few
+	messages for clarity.
+
+	Continues the long process of fixing Savannah #52463.
+
+2022-06-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/devices/gropdf/gropdf.pl (Load_Config): Drop unused
+	subroutine and its commented-out call site, which came in that
+	way in July 2011.
+
+2022-06-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/devices/gropdf/gropdf.pl (LoadFont): Warn if a font to be
+	embedded in PDF output cannot be located in the "download" file.
+
+	Fixes <https://savannah.gnu.org/bugs/?62572>.  Thanks to Deri
+	James.
+
+2022-06-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/a4.tmac: Drop file from distribution.  It has been
+	superseded by papersize.tmac for nearly 20 years.
+	* tmac/tmac.am (TMACNORMALFILES): Delete reference.
+	* NEWS: Add item.
+
+	Fixes <https://savannah.gnu.org/bugs/?62569>.
+
+2022-06-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[build]: Parameterize X11-related man pages, so they don't get
+	spuriously generated (and not cleaned) when building with X11
+	support disabled.
+
+	* Makefile.am (.man): Fix logic nit: drop unnecessary removal of
+	target before clobbering it with sed.
+	* src/devices/xditview/xditview.am (GXDITVIEW_MAN1): Add new
+	macro, expanding to nothing if `WITHOUT_X11` and to the target
+	name otherwise.
+	(man1_MANS): Append `GXDITVIEW_MAN1` expansion, not a literal.
+	* src/devices/xditview/xditview.am (XTOTROFF_MAN1): Add new
+	macro, expanding to nothing if `WITHOUT_X11` and to the target
+	name otherwise.
+	(man1_MANS): Append `XTOTROFF_MAN1` expansion, not a literal.
+	* doc/doc.am (GROFF_MAN_PAGES1): Append foregoing expansions
+	instead of literals.
+
+2022-06-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* configure.ac: Add `AM_CONDITIONAL`: `HAVE_URW_FONTS`, so our
+	Automake files can more easily cope with their absence.
+	* font/devpdf/Foundry.in: Add easily matched phrases to
+	comments, to clearly delimit the URW foundry portion of the file
+	so it can be omitted if those fonts are absent.
+	* font/devpdf/devpdf.am (font/devpdf/Foundry): Generate file
+	differently depending on `HAVE_URW_FONTS`; keep the existing
+	procedure if true, and delete the URW section from the generated
+	file otherwise, avoiding diagnostic messages from afmtodit(1)
+	and our BuildFoundries script.
+
+	Fixes <https://savannah.gnu.org/bugs/?62570>.
+
+2022-06-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* font/devpdf/devpdf.am (font/devpdf/util/BuildFoundries):
+	Generate script using the `PATH_SEPARATOR` Automake macro.
+	* font/devpdf/util/BuildFoundries.pl: Add `pathsep` scalar to
+	house the build-time path separator.
+	(LocateFile): Use it.
+	(LoadFoundry, CheckFoundry): Stop using spaces as part of the
+	path separation delimiter.  It is not idiomatic.
+
+2022-06-02  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* configure.ac: Explicitly identify poppler tools in report.
+
+2022-06-02  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* font/devpdf/util/BuildFoundries.pl: Trivially refactor.  Drop
+	unused hash `foundry`.  Drop scalar `warn` that was set and
+	updated but never tested.
+
+2022-06-02  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* font/devpdf/util/BuildFoundries.pl: Alter script to write to
+	the standard output stream instead of (re)writing a file named
+	"download" in the current working directory.  This recovers from
+	a problem I introduced in commit 6e62be835d, 2 May, as an
+	unforeseen side effect of improving build parallelism so that
+	the "download" file wouldn't be read until it was fully
+	populated.  As a side benefit, this approach is more Unixy, and
+	less dependent on $PWD.
+	(top level): Stop calling `WriteDownload` with an argument.
+	(LoadFoundry): Close only the file handle of interest when done,
+	not all of them (including `STDOUT`, which we now need).
+	(CheckFoundry): Same--just for cleanliness, since at present
+	running the script in 'check' mode doesn't write to any streams.
+	(WriteDownload): Stop taking an argument and manipulating file
+	handles.  Write download file to standard output.
+	(LoadDownload, WriteDownload): Drop `top` scalar, used as a
+	mutex to serialize read and write access to "download" file; it
+	is no longer needed since the "download" file is now only read.
+
+2022-06-01  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[build]: Rename shell variables and Autoconf/Automake macros of
+	Boolean sense to have names more like logical predicates and
+	avoid doofy "DONT" nomenclature.
+
+	* m4/groff.m4 (GROFF_MAKE_RM): Rename shell variable
+	`groff_is_rm_defined` to `groff_make_defines_rm` (purely for
+	clarity; it already had a good name).
+	(GROFF_MAKE_RM): Rename this...
+	(GROFF_MAKE_DEFINES_RM): to this, to make parallelism obvious,
+	and enabling...
+	* configure.ac: ...rename of `MAKE_DONT_HAVE_RM` to
+	`MAKE_DEFINES_RM` with sense of test reversed.  Also interpolate
+	`GROFF_MAKE_DEFINES_RM` instead of `GROFF_MAKE_RM`.  This in
+	turn enables...
+	* Makefile.am: ...revision of conditional from
+	`MAKE_DONT_HAVE_RM` to "!`MAKE_DEFINES_RM`".
+
+2022-06-01  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_URW_FONTS_PATH)
+	(GROFF_WITH_COMPATIBILITY_WRAPPERS, GROFF_APPDEFDIR_OPTION)
+	(GROFF_UCHARDET): Recast help strings to more closely parallel
+	structure and style of Autoconf's own help strings.
+	(GROFF_WITH_COMPATIBILITY_WRAPPERS): Recast to tighten wording.
+
+2022-06-01  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* configure.ac:
+	* m4/groff.m4 (GROFF_APPDEFDIR_OPTION, GROFF_APPDEFDIR_DEFAULT)
+	(GROFF_APPDEFDIR_CHECK): Rename m4 macros and shell variable
+	from "*appres*" to "*appdef*.  Update interpolation sites.
+
+	* configure.ac:
+	* m4/groff.m4 (GROFF_APPDEFDIR_CHECK): Further rename this...
+	(GROFF_APPDEFDIR_NOTICE): ...to this, for consistency with other
+	post-report output macros.
+
+	* Makefile.am:
+	* PROBLEMS:
+	* doc/automake.mom:
+	* src/devices/xditview/xditview.am: Update interpolation sites
+	of `appresdir`.
+
+	* Makefile.am:
+	* src/devices/xditview/gxditview.1.man:
+	* src/roff/groff/groff.1.man: Update interpolation sites of
+	`APPRESDIR`.
+
+	* NEWS: Add item.
+
+2022-06-01  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_X11, GROFF_UCHARDET): Drop redundant
+	messages (which are easily overlooked amid the torrent of
+	"checking" output anyway).  Discovery failures of X11 and the
+	uchardet library are already parts of the configuration report
+	at or near the end of output.
+
+2022-06-01  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_PNMTOPS_NOSETPAGE): Partially revert change
+	from 21 May and document why in a comment.
+
+2022-06-01  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/troffrc: Skip loading of "papersize.tmac" if not in troff
+	mode.
+
+	Fixes <https://savannah.gnu.org/bugs/?62238>.  Thanks to Bjarni
+	Ingi Gislason for the report.
+
+2022-05-31  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* configure.ac: Report use of "g" prefix for commands and macro
+	package compatibility wrappers.
+	* m4/groff.m4 (GROFF_G): Fix code style nits.  Update
+	indentation to match recent practice.
+
+2022-05-31  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* configure.ac: Fix code style nits and tweak report.  Stop
+	superfluously using braces for shell parameter expansions that
+	don't require them.  The shell is not make(1).  Say
+	"installation _directory_ prefix" since another kind of prefix
+	can be used by groff (the "g" in front of command and macro
+	package names shared with AT&T troff).
+
+2022-05-31  Dave Kemper <saint.snit@gmail.com>
+
+	* doc/groff.texi: Fix content and style nits.
+	  - Remove redundancy ("fixed-width... character that can't be
+	    adjusted").
+	  - Fix incorrect word ("environment value" -> "environment
+	    variable").
+	  - Add or change the placement of a couple tie{}s to comport
+	    with style-guide recommendation.
+	  - Grammarify.
+	  - Clarify and tighten wording.
+
+	Fixes <https://savannah.gnu.org/bugs/?62551>.
+
+2022-05-30  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/roff/troff/node.cpp (font_position): If mounting a font
+	fails and a third argument was given (to the `fp` request),
+	report its value in the diagnostic message.  This could reveal a
+	prohibited attempt at directory traversal.  See commit
+	a891161bc9, 7 November.
+
+2022-05-30  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/libs/libgroff/fontfile.cpp (font::open_file): Refactor.
+	Move more logic, including memory allocation, inside conditional
+	that accepts only file names without '/' characters, skipping
+	unnecessary work in the alternative.  Annotate use of zero
+	literals as null pointers to ease any future migration to ISO
+	C++11.  Add 'const' qualifier to variable that doesn't require
+	modification (and which is used in the LHS of an equality
+	comparison, so that clumsy operator misuse will provoke a
+	compiler warning).
+
+	Fixes <https://savannah.gnu.org/bugs/?62532>.  Thanks to Bjarni
+	Ingi Gislason for the report.
+
+2022-05-30  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* configure.ac: In configuration report, say that we're
+	reporting compiler options along with the compiler executable.
+	Fix leftover test(1) comparison with garbage, overlooked in
+	commit faa22d89d2, 20 May.
+
+2022-05-30  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (doc/meintro_fr.ps): Build with '-t' option.
+
+	Fixes <https://savannah.gnu.org/bugs/?62542>.  Thanks to Bjarni
+	Ingi Gislason for the report.
+
+2022-05-28  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/roff/groff/groff.1.man (Options) <-l>: Handle case where
+	no default print spooler is configured, and report formatter
+	behavior correctly if it isn't.
+
+	Fixes <https://savannah.gnu.org/bugs/?62535>.  Thanks to Bjarni
+	Ingi Gislason for the report.
+
+2022-05-28  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* Makefile.am (.man): Process '@PSPRINT@' substitutions with
+	"makevarescape.sed".
+
+2022-05-26  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_PROG_YACC, GROFF_MAKEINFO, GROFF_TEXI2DVI):
+	Fix logic error in detection of build scenario: the presence of
+	a ".git" directory is not an indicator that we're not building
+	from a distribution archive, because we might be building from a
+	snapshot archive (which also lacks it).  Instead, perform checks
+	required only by builds from Git checkouts and snapshot archives
+	if the ".tarball-version" file is not present.
+
+2022-05-26  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* Makefile.am (EXTRA_DIST): Ship "HACKING" file.
+
+2022-05-26  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* bootstrap.conf: Add "pkg-config" to `buildreq`.  Not having it
+	causes pretty horrible macro expansion problems and diagnostics
+	when 'autoreconf' is run; they're still pretty bad even if you
+	use `AC_REQUIRE` and `m4_pattern_forbid`.  So just demand it.
+
+2022-05-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* font/devps/S:
+	* font/devps/symbolmap: Drop excess mapping of `*U` special
+	character.  groff maps it to the Adobe Glyph List name
+	'Upsilon1'.  (The AGL 'Upsilon' is a homoglyph of the Latin
+	capital 'Y'.)
+	* PROBLEMS: De-document build-time warning, now resolved.
+
+2022-05-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/utils/afmtodit/afmtodit.tables: Regenerate using Unicode
+	14.0.  No substantive changes.
+
+2022-05-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/utils/afmtodit/make-afmtodit-tables: Refactor.  Drop
+	unused variable `prog`.  Use value of `CPP` from environment (if
+	defined) and use parameter expansion to apply a default if null
+	or not set.  Use for loop to eliminate duplicative if statement.
+	Test input files for readability, not just existence.  Use more
+	portable test(1) and shell syntax.  Swap usage error and fatal
+	error exit statuses; using "1" for failure and "2" for usage
+	errors is more common in shell scripts I've seen.  Update usage
+	message to put non-literal parameter in full caps, and clarify
+	its name.  Update comment blocks written to generated files to
+	further clarify data provenance.
+
+2022-05-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_PRINT): Refactor.  Stop performing checks
+	for spooler options if none is available.  Stop redundantly
+	reporting command name used for spooling PostScript files.  If
+	an option is required for spooling DVI files, report it alone
+	instead of repeating the command name as well.
+
+2022-05-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Fix insensitivity of groff(1) man page to configured spooler.
+
+	* Makefile.am (.man): Replace `@PSPRINT@` in man page sources
+	with name of configured print spooler command.
+	* src/roff/groff/groff.1.man (Options) <-l>: Use configured
+	print spooler command instead of literal 'lpr'.
+
+2022-05-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_UCHARDET_CHECK): Fix grammar nit in failure

+	cannot be located.
+
+2022-05-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+

+	computation of verb to be used in notice message.
+
+2022-05-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_PROG_YACC, GROFF_URW_FONTS_CHECK)
+	(GROFF_WITH_COMPATIBILITY_WRAPPERS, GROFF_UCHARDET_NOTICE):
+	Improve shell code portability.  Per the GNU Autoconf manual,
+	"The -a, -o, '(', and ')' operands are not present in all
+	implementations, and have been marked obsolete by Posix 2008.
+	...portable uses of test should never have more than four
+	arguments, and scripts should use shell constructs like '&&' and
+	'||' instead."
+
+2022-05-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/roff/groff/groff.1.man (Installation directories): Don't
+	output a tagged paragraph for the X11 application defaults
+	directory if the build symbol '@APPRESDIR@' is not defined (that
+	is, we didn't build with X11 support).
+
+2022-05-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_GHOSTSCRIPT_VERSION_CHECK): Fix code style
+	nits.  Use lowercase for shell variables we define.  Don't quote
+	literal operands to test(1) that don't contain syntactically
+	shell-significant characters.  Update indentation to match
+	recent practice.
+
+2022-05-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_URW_FONTS_NOTICE): Don't emit the notice if
+	Ghostscript isn't available, since it was a prerequisite for
+	the `GROFF_URW_FONTS_CHECK` macro in the first place.
+
+2022-05-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[build]: Add print spooler determination to configuration
+	report.
+
+	* m4/groff.m4 (GROFF_PRINT): Add shell variable

+	{"lp" or "lpr"} or the word "no".
+	* configure.ac: Report determined spooler, or its absence.

+
+2022-05-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_CHECK_GROHTML_PROGRAMS): Migrate from

+	GNU Autoconf 2.70 or later.
+
+	Fixes <https://savannah.gnu.org/bugs/?61059>.  Thanks to Bjarni

+
+2022-05-22  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* man/groff.7.man: Rename "pilot" list macros for man(7) from

+
+2022-05-21  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_MAKEINFO, GROFF_TEXI2DVI): Check for

+	not a distribution archive.
+
+2022-05-21  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (doc/meintro_fr.ps): Call groff with `-K utf8`
+	instead of `-k`, in case the "configure" script didn't find
+	uchardet (and preconv(1) thus can't auto-detect an encoding).
+
+	Fixes <https://savannah.gnu.org/bugs/?59463>.

+2022-05-21  G. Branden Robinson <g.branden.robinson@gmail.com>
+

+
+2022-05-21  G. Branden Robinson <g.branden.robinson@gmail.com>
+

+
+2022-05-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Handle missing programs required to construct files needed at

+
+	* configure.ac:
+	* m4/groff.m4: Rename `GROFF_PDFDOC_PROGRAMS` macro to
+	`GROFF_CHECK_GROPDF_PROGRAMS`.  Rename shell variable
+	`make_pdfdoc` to `use_gropdf`.  Set it explicitly to "no" or
+	"yes" instead of null or not null.
+
+	* configure.ac:
+	* m4/groff.m4:
+	* doc/doc.am: Rename `BUILD_PDFDOC` to `USE_GROPDF`.
+
+	* configure.ac: Call `GROFF_GROPDF_PROGRAM_NOTICE`.
+
+	* doc/doc.am: Bracket definition of `PROCESSEDDOCFILES_PDF`
+	macro and `$(PROCESSEDDOCFILES_PDF)` dependency declaration in
+	Automake `if USE_GROPDF` conditional.  This prevents attempts
+	to build PDF documents using groff that are doomed to fail.
+
+	* m4/groff.m4: Refactor gropdf runtime-dependency program check.
+	Split into two macros: one (`GROFF_CHECK_GROPDF_PROGRAMS`)
+	performs the check, the other (`GROFF_GROPDF_PROGRAM_NOTICE`)
+	issues a notice at the end of the configuration process if at
+	least one program was not found.  Rename `docnote` shell
+	variable to `gropdf_notice`.  Tighten wording of notice.  Drop
+	unused `make_install_pdfdoc` and `make_uninstall_pdfdoc` shell
+	variables.
+
+2022-05-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Handle missing programs required at runtime by grohtml more
+	gracefully.  Rename and refactor configuration-time logic to be
+	more understandable.
+
+	* configure.ac:
+	* m4/groff.m4: Rename `GROFF_HTML_PROGRAMS` macro to

+
+	* doc/doc.am: Bracket definition of `PROCESSEDDOCFILES_HTML`
+	macro and `$(PROCESSEDDOCFILES_HTML)` dependency declaration
+	in Automake `if USE_GROHTML` conditional.  This prevents an
+	attempt to build an HTML version of the "pic.ms" document that
+	is doomed to fail (noisily).
+
+	* m4/groff.m4: Refactor grohtml runtime-dependency program
+	check.  Split into two macros: one
+	{`GROFF_CHECK_GROHTML_PROGRAMS`} performs the check, the other
+	{`GROFF_GROHTML_PROGRAM_NOTICE`} issues a notice at the end of
+	the configuration process if at least one program was not found.
+	Rename `html_docnote` shell variable to `grohtml_notice`.

+
+2022-05-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_GHOSTSCRIPT_VERSION_NOTICE): Add newline at

+
+2022-05-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Check for m4 program at configuration time.
+

+	* configure.ac: Call the new macro.
+	* tmac/tmac.am (tmac/groff_man.7.man)
+	(tmac/groff_man_style.7.man): Use the new implicitly AC_SUBST-ed

+
+2022-05-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_PROG_YACC): Update wording of error

+	not found (along with "byacc" and "bison").
+
+2022-05-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* configure.ac: Fix shell style nits.  Get rid of string
+	{non-}nullity tests and comparisons involving concatenation with
+	garbage (usually "x").  See 13 November entry regarding m4.  Use
+	idiomatic shell "brace style" for control structures.
+
+2022-05-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Trivially refactor libgroff allocator configuration.
+
+	* m4/groff.m4 (GROFF_USE_GROFF_ALLOCATOR): Update description of
+	configuration flag to clarify that it's implemented in a
+	library.  Rename shell variable to prefix it with "groff_",
+	putting it in an ad hoc name space as with other variables.  If
+	feature disabled, set variable to literal "no".
+	* configure.ac: Use renamed variable and interpolate it directly
+	into configuration report, simplifying shell logic.
+
+2022-05-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* configure.ac: Revise configuration report for intelligibility.
+	Add report of C++ compiler and flags used: we compile much more
+	C++ than C code so this seems appropriate.  Report Perl
+	interpreter version so that we can collect build reports and
+	turn the ratchet past Perl 5.6.1 at some point.  Fix X11
+	"resources" misnomer (application defaults are what is meant).
+	Rephrase generally.
+
+2022-05-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* Makefile.am (EXTRA_DIST): Ship "ChangeLog.122" in distribution

+
+2022-05-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/devices/grotty/tests/basic_latin_glyphs_map_correctly.sh:
+	Fix portability problem: POSIX says that "od -c" (and "od -t c")
+	are supposed to emit printing characters as defined by the
+	underlying locale, but GNU coreutils od doesn't do this and
+	macOS od does.  Set `LC_ALL` to "C" when running it to force
+	3-digit octal reporting of characters with their eighth bit set.
+
+	Fixes <https://savannah.gnu.org/bugs/?62357>.  Thanks to John
+	Gardner for the report.  Also see <https://pubs.opengroup.org/\
+	onlinepubs/9699919799/utilities/od.html>.
+
+2022-05-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* INSTALL.extra (In Case of Trouble): Add advice on using the

+
+2022-05-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/groff.texi (Input Line Traps):  Expand discussion.  The
+	`it` and `itc` requests count neither input lines (strictly) nor
+	text lines.  Instead, they count input lines that _directly
+	produce formatted output_ (and, in the case of `itc`, are not
+	"interrupted" or continued with the `\c` escape sequence).  This
+	is useful--empty requests and requests that don't put nodes on
+	the output don't break things--but does demand some explanation.
+	Clarify and provide example.
+	* man/groff.7.man (Escape sequence short reference) <it>: Sync.
+
+2022-05-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+

+2022-05-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/devices/grotty/tty.cpp (tty_printer::add_char): Modify
+	diagnostic message: what gets written "above [the] first line"
+	might not be a character (glyph) per se, but a line (rule) from
+	a drawing command, and in fact the occurrence of these from
+	boxed tables is the most common cause of this message I've seen.
+
+2022-05-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[grotty]: Do more input validation.
+
+	* src/devices/grotty/tty.cpp (tty_printer::draw): Throw warning
+	if an unsupported geometric primitive is encountered.
+	(tty_printer::line): Throw warning if a line is diagonal.  Die
+	if length of a horizontal or vertical line is not a multiple of
+	the appropriate motion quantum of the device (troff should never
+	emit such nonsense, and currently doesn't appear to).
+
+2022-05-16  G. Branden Robinson <g.branden.robinson@gmail.com>

+	* src/roff/troff/mtsm.cpp (no_of_statems): Place global variable
+	behind `DEBUGGING` preprocessor symbol, omitting it from
+	production and ordinary development builds.
+	(statem::statem): Make constructor trivial if `DEBUGGING` not
+	defined in preprocessor; it manipulates only `issue_no` and
+	`no_of_statems`, which are synchronized.
+	(statem::statem {copy}): Gate assignment of `issue_no` member
+	variable from copy constructor behind `DEBUGGING` preprocessor
+	symbol.
+	(statem::flush, mtsm::inherit): Gate debugging output, already
+	runtime-gated on `debug_state` symbol, of `issue_no` member
+	variable, so that we don't reference it when it is not declared.
+
+	See <https://savannah.gnu.org/bugs/?62040>.
+
+2022-05-05  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[refer]: Rename a test artifact; it's a bibliographic database
+	file, not a refer(1) command file.
+
+	* src/preproc/refer/tests/artifacts/62124.ref: Rename this...

+
+2022-05-05  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/refer/command.cpp (process_commands): Begin
+	migration to use existing global variables for location reports
+	in diagnostic messages.  Save current file name and line number
+	before calling `command_loop()` and restore them afterward.
+	Also decrement line counter before entering that loop because it
+	would be too far advanced by one due to the final newline on a
+	parsed input line.
+
+2022-05-05  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/refer/refer.cpp (main): Report system error on

+
+2022-05-04  G. Branden Robinson <g.branden.robinson@gmail.com>

+
+2022-05-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+

+

+
+	* src/preproc/refer/command.cpp (input_stack::push_file):
+	* src/preproc/refer/refer.cpp (do_file): Drop unnecessary
+	construction of integer from integer (return type of `getc()`)
+	in argument to error diagnostic functions; parallelizes with
+	other diagnostic function calls.
+
+2022-05-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/refer/command.cpp: Refactor to simplify.
+	(get_location): Demote return type from `int` to `void`.  The
+	function only ever returned a `1` literal.
+	(input_stack::error): Update call site to stop uselessly testing
+	return value of `get_location()`.
+
+2022-05-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (dist-info-bits, install_infodoc, dist-gnueps): Fix
+	logic error.  When checking both source and build trees for
+	files to copy, break after successfully copying the files, not
+	after the first iteration of the loop unconditionally.  This
+	caused the Info documents not to be installed from out-of-tree
+	builds, and potentially would prevent them and doc/gnu.eps from
+	being included in the distribution archive if for some reason
+	they didn't build and that build failure were not treated as an
+	error.  Problems introduced by me in commits e78bd20d54, 27
+	March, and d79c3f3a4a, 11 November.
+
+2022-05-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_APPRESDIR_OPTION): Update comments and
+	human-readable output to (1) stop claiming that existing
+	gxditview application defaults in the installation directory
+	will be backed up; this is no longer true as of commit
+	c66cb7725f, 3 April; and (2) refer to these files as
+	"application defaults", not "resources".  (X11 application
+	defaults are client-side and mandatory [for Xt-based programs];
+	X resources are stored server-side and need not be configured to
+	determine an X client's geometry and rendering.)

+
+2022-05-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* font/devpdf/devpdf.am (font/devpdf/util/BuildFoundries): Spell
+	dependency on `$(SH_DEPS_SED_SCRIPT)` using that macro expansion

+	* src/preproc/eqn/eqn.am (MAINTAINERCLEANFILES):
+	* src/preproc/pic/pic.am (MAINTAINERCLEANFILES):
+	* src/preproc/refer/refer.am (MAINTAINERCLEANFILES): Preserve
+	byacc/bison output artifacts unless "maintainer-clean"ing.  Per
+	the GNU Automake manual, "The intermediate files generated by
+	yacc (or lex) will be included in any distribution that is made.
+	That way the user doesn’t need to have yacc or lex."
+
+2022-05-02  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* Makefile.am: Stop manually handling "test-groff".  Per the
+	GNU Automake manual, "If configure built it, then distclean
+	should delete it."  This is taken care of automatically if we
+	don't interfere.
+	(BUILT_SOURCES, MOSTLYCLEANFILES): Drop "test-groff".
+
+2022-05-02  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/eqn/eqn.am (neqn): Produce temporary file first
+	and set its permissions before moving it into place.  If
+	anything in the future ever has a dependency on it, this avoids
+	a race where the file exists, satisfying a dependency, but
+	execution is attempted before its `x` permission bit is set.
+
+2022-05-02  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[build]: Ensure that we install *.me source files, but don't
+	include them in the distribution archive.
+
+	* doc/doc.am (dist_otherdoc_DATA): Move `$(GENERATEDDOCFILES)`
+	from here...
+	(nodist_otherdoc_DATA): ...to here.
+	(.PRECIOUS): Add `$(GENERATEDDOCFILES)` so that make(1) doesn't
+	automatically remove "intermediate" objects in the .me.in -> .me
+	-> .ps chain.
+
+2022-05-02  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[build]: Handle "gnu.eps" file better.
+
+	* doc/doc.am (GENERATEDDOCFILES): Remove `$(DOC_GNU_EPS)`.
+	(EXTRA_DIST): Ship `$(DOC_GNU_EPS)` in distribution archive.
+	($(DOC_GNU_EPS)): Simplify rule commands; stop trying to copy
+	the file around since it will either be (1) in the distribution
+	archive from which a build is performed; or (2) missing because
+	a build is being done from Git, in which case we expect the PNM
+	tools to be available.
+
+2022-05-02  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (clean_otherdoc): Drop target: it doesn't seem to
+	accomplish anything.
+	(clean_infodoc): Drop target, moving its rules into...
+	(maintainer-clean-local): ...this.  Drop deps, both gone now.
+
+2022-05-02  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (distclean-local): Drop target: stop cleaning
+	generated forms of our Texinfo manual with the "distclean"
+	target.  They ship with the distribution archive and should
+	remain in the tree even if the user needs to re-./configure.
+
+2022-05-02  G. Branden Robinson <g.branden.robinson@gmail.com>

+	(font/devpdf/DESC, font/devpdf/Foundry): Drop
+	unnecessary removal of target prior to creating it.
+	(font/devpdf/Foundry): Add creation of destination build
+	directory as other targets do.
+	(font/devpdf/download): Create dedicated target instead of
+	lumping its generation under the stamp file.  Add missing
+	dependencies on `$(DEVPDFFONTMAP_1)`, `$(DEVPDFFONTMAP_2)`,
+	`font/devpdf/Foundry` and `font/devpdf/enc/text.enc`.  Remove
+	now-unnecessarily complicated "forgery" of "GEN" line in quiet
+	builds.  Tweak format of comment written to "download" file to
+	make field identities clearer.  Construct output (with multiple
+	shell commands) in temporary file so it is not read prematurely
+	by the "BuildFoundries" script.  Move target into place as the
+	last step.
+	(font/devpdf/stamp): Relocate target to follow its dependencies.
+	Add dependency on "font/devpdf/download".

+	(usage): Document --version option.  Use more informative
+	metasyntactic variable names.  Organize usage message
+	consistently with our others, and stop wrapping the output

+	Lift extraction of entry string to be done unconditionally,

+	When using just `-man`, the problem never manifested; only with
+	`-mandoc`.  The difference is that with the former, the `.$`
+	register is initialized to zero; with the latter, because `TH`
+	is aliased to another macro (then unaliased), `.$` has the
+	argument count to the `TH` macro, not to the macros actually

+	[man]: Add regression test for Savannah #62257.
+
+	* tmac/tests/an_do-not-abbreviate-escape-using-TH-arguments.sh:
+	Do it.
+	* tmac/tmac.am (tmac_TESTS): Run it.
+
+2022-04-08  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an.tmac: Trivially refactor.  Rename strings `an-ifoot`
+	to `an*ifoot` and `an-outer-footer-text` to `an*ofoot`.
+
+2022-04-08  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an.tmac: Refactor.  Abbreviate page title and inner
+	footer only once per document instead of once per page.
+	Exception: the legacy macros `AT` and `UC` change the inner
+	footer, so re-abbreviate it if they are called.
+	(TH, AT, UC): Call abbreviation macros from here...
+	(an-header, an-footer): ...instead of here.
+
+2022-04-08  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an.tmac: Refactor: initialize header/footer environment
+	only once.  Also rename it to `an*env-header-and-footer`.
+	(TH): Do it here...
+	(an-header, an-footer): ...instead of here.
+
+2022-04-08  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an.tmac: Trivially refactor.
+	(an*prepare-page-title): Rename this...
+	(an*abbreviate-page-title): ...to this.
+	(an-prepare-inner-footer): And this...
+	(an*abbreviate-inner-footer): ...to this.
+	(an-header, an-footer): Update call sites.
+
+2022-04-08  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/eqn/other.cpp (hmotion_box::output): Fix typo in
+	generated MathML diagnostic message.
+
+2022-04-07  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (EXTRA_DIST): Add "groff.dvi" and "groff.pdf" to
+	ensure that the GNU-released groff distribution archive contains
+	our Texinfo manual in these formats.  (This doesn't increase the
+	build-dependency requirements unless you want to "make dist", in
+	which case it _should_.)
+
+2022-04-06  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[ms]: Add nroff mode fallback for `UL` macro.
+
+	* tmac/s.tmac (UL): On nroff devices, bracket the first argument
+	with \(ul (underline rule) special character escape sequences.
+	{In plain language, '.UL "like this"' renders "_like this_".}
+	See corresponding 12 February change to "tmac/e.tmac".
+
+2022-04-06  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Drop unnecessary `-I` options to groff.
+	(DOC_GROFF): There is no need to look at the top of the build
+	directory for any file inclusions.
+	(doc/webpage.html): There is no need to look in `doc_builddir`
+	for file inclusions, since that is the current working directory
+	when "webpage.ms" is processed.
+
+2022-04-06  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Trivially refactor.  Use `RM` macro idiomatically.
+	Automake ensures that it is defined to call an `rm` command with
+	the `-f` option, and this in turn ignores failures to delete
+	nonexistent files, so...
+	(uninstall_doc_examples, uninstall-pdf): Stop adding superfluous
+	`-f` flag.
+	(clean_infodoc uninstall-pdf, uninstall-html): Stop prefixing
+	command with `-` to ignore error exit status.
+	(uninstall-html): Drop superfluous `-r` flag; we're only
+	deleting files with this command, not directories.
+
+2022-04-05  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Trivially refactor shell style in rule commands.
+	The placement of `&&` was inconsistent.  Always begin a
+	continued rule line with it, and don't give it its own
+	indentation level.  In general, operators adjacent to line
+	continuations should _follow_ the continuations because they are
+	easier for humans to spot at the (possibly indented) beginning
+	of a physical line.
+
+2022-04-05  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* Makefile.am: Rename `TFLAG` macro, which means "tmac flag", to
+	`MFLAG`, because it expands to `-M` options to groff, not the
+	`-T` option, which can be bewildering.
+	* doc/doc.am (DOC_GROFF): Update expansion site.
+
+2022-03-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Rename `DOC_GROFF_ONLY` to `DOC_GROFF`.
+
+2022-03-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Refactor.  Drop ghastly hack used to get file
+	names into troff diagnostics when reading from standard input.
+	We've refactored so that it no longer does, making the hack
+	unnecessary.  For the same reason, no users of the `DOC_GROFF`
+	macro remain, so delete it.  Add comments to explain what
+	`DOC_SED` and `DOC_GROFF_ONLY` are for.
+
+2022-03-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Refactor.
+	(doc/pic.html, doc/webpage.html): Drop indirection of source
+	document through `DOC_SED` macro.  It was not necessary since
+	neither of these documents are parameterized in configuration
+	options (that is, they don't contain @VERSION@ or @g@).
+
+2022-04-05  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Trivially refactor.
+	(doc/webpage.html): Tidy up dependency list.  Create directory
+	using the same macro interpolation we use to change into it.
+
+2022-04-05  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Refactor and fix error in builds in remote
+	out-of-source-tree builds exposed by pending commit and `make
+	distcheck`.  The images generated for the pic.html and
+	webpage.html files were being built in the wrong directory, and
+	subsequently not found by an install rule.
+	(imagedir): Add comment explaining purpose of macro.  It should
+	_not_ be used with any file specifications relative to the
+	source or build trees--it is for installation directories only.
+	(htmldocimagedir, exampleimagedir): Drop macros.
+
+	(doc/pic.html, doc/webpage.html): Replace interpolations of
+	`imagedir` with literal "img", since these files are being
+	generated within the build tree: the directory name is known.
+
+	(mostlyclean_doc, install_doc_htmldoc, install_doc_examples):
+	Replace interpolations of `htmldocimagedir` relative to
+	`doc_builddir` with "img" literals.
+
+	(install_doc_htmldoc, uninstall_doc_htmldoc): Interpolate
+	concatenation of `htmldocdir` and `imagedir` instead of
+	`htmldocimagedir` (relative to `DESTDIR`).
+	(install_doc_examples, uninstall_doc_examples): Interpolate
+	concatenation of `exampledir` and `imagedir` instead of
+	`exampleimagedir` (relative to `DESTDIR`).
+
+2022-04-01  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Refactor.  Relocate "doc/grnexampl.ps" target to
+	group it with other me(7) documents.  Put addition of
+	"doc/examples.stamp" to `MOSTLYCLEANFILES` adjacent to its
+	target rule.  Relocate same rule so that it precedes the target
+	depending on it (make(1) might not benefit from this, but human
+	readers can).
+
+2022-03-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Refactor.
+	(DOC_GROFF_ONLY): Drop preprocessor options from groff command.
+	This macro is now, simply, a way to run the in-tree groff: no
+	assumptions about preprocessors, macro packages, or output
+	device are made.
+	(doc/pic.html, doc/webpage.html): Add only necessary
+	preprocessor options after expansion of `DOC_GROFF_ONLY`.
+
+2022-03-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Refactor.  Add explicit dependencies of compiled
+	man page documents on preprocessors needed to generate them.  In
+	their target rules, explicitly use groff's preprocessor options,
+	freeing us up to simplify the `DOC_GROFF_ONLY` macro.
+
+2022-03-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Rationalize dependencies.  Drop dependency of
+	`PROCESSEDEXAMPLEFILES` and `PROCESSEDDOCFILES` on expansion of
+	`hdtbltmac_DATA`, because nothing in this directory uses the
+	hdtbl package.  Move dep of same expansions on "gnu.eps" to
+	"doc/webpage.html", which actually uses it.  Put the numerous
+	dependencies of "doc/pic.html" and "doc/webpage.html" in a
+	parallel ordering so that they are easier for humans to
+	evaluate.  These targets' dependencies on `bin_PROGRAMS` and
+	`prefixexecbin_PROGRAMS` are overkill and should be reviewed at
+	a later date.
+
+2022-04-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Refactor use of target and suffix rules.
+	(doc/meintro.me, doc/meintro_fr.me, doc/meref.me): Add target
+	rules, with lengthy, exasperated comment about lack of feature
+	parity in various make(1) implementations.
+	(doc/meintro_fr.ps): Add target rule, as this seems to be the
+	only way to keep GNU Make from ignoring a '_fr.me._fr.ps' suffix
+	rule in favor of '.me.ps', which doesn't call preconv (and
+	doesn't need to--and moreover we don't want to build English
+	me(7) documents with the `-mfr` option).  Depend on `preconv`.
+	(doc/webpage.ps): Convert from suffix rule to target rule.
+	(doc/ms.ps, doc/pic.ps, doc/webpage.ps): Add target rules and
+	dependencies.
+	(.ms.ps): Add commented-out suffix rule (since nothing uses it,
+	but might in the future).
+	(doc/meintro_fr.ps, .me.ps, doc/pic.ps, doc/webpage.ps): Migrate
+	expansions of `DOC_GROFF` to `DOC_GROFF_ONLY` to prepare for a
+	forthcoming simplification.
+
+2022-04-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Clean generated doc files better.  doc/me*.me were
+	getting left behind in the build tree.
+	(MOSTLYCLEANFILES): Add `GENERATEDDOCFILES`.  This includes
+	`DOC_GNU_EPS`, so...
+	(clean_maintdoc): Drop phony target that manually removes it.
+	(maintainer-clean-local): Drop dependency on foregoing.
+
+2022-04-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/devices/xditview/xditview.am (install_xditview)
+	[!WITHOUT_X11]: Stop backing up existing "GXditview" and
+	"GXditview-color" application defaults files.  There is no
+	symmetric restoration of them in the uninstall target, and it
+	seems like unjustifiable complexity to add such.  These are
+	groff-specific file names, installed (by default) to /usr,
+	not /etc, so they are not going to be "configuration files" in
+	Debian-based systems, for example (and likely not elsewhere).
+	There are other ways to supersede application defaults for
+	programs using the X Toolkit Intrinsics.
+
+2022-04-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Stop treating "gnu.eps" as an "example" file; it
+	is also used by pdfmark's cover.ms, which is ordinary
+	documentation.  We therefore must not omit it when building.
+	(install-data-hook): Add dependency on new phony target,
+	"install_doc_gnu_eps".
+	(install_doc_examples): Move installation of "gnu.eps" from
+	here...
+	(install_doc_gnu_eps): ...to here.  Also refactor the loop we
+	use to locate the file to follow a more idiomatic pattern.
+
+2022-04-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (dist-info-bits, install_infodoc, dist-gnueps): Fix
+	code style nit: use consistent "brace style" in conditionals and
+	loops.
+
+2022-04-01  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (mostlyclean_doc): When cleaning, try harder to
+	remove the image directory created by the "pic.html" and
+	"webpage.html" targets.
+
+2022-04-02  Ingo Schwarze <schwarze@openbsd.org>
+
+	* doc/doc.am: Stop installing doc/meintro.me.in,
+	doc/meintro_fr.me.in, and doc/meref.me.in.
+
+2022-03-30  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/webpage.ms: Die horribly if `PSPIC` call fails.
+
+2022-03-30  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/pspic.tmac (pspic*error-hook): Define (as empty).
+	* man/groff_tmac.5.man (Auxiliary packages) <pspic>: Document.
+	* NEWS: Add item.
+
+2022-03-29  G. Branden Robinson <g.branden.robinson@gmail.com>

+
+	* tmac/tests/pdfpic_does-not-choke-on-bad-pdfinfo-output.sh:
+	* tmac/tests/pdfpic_falls-back-to-PSPIC.sh: Remove output file

+	with `test -z`.
+
+2022-03-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* man/groff_tmac.7.man (Auxiliary packages): Tweak sboxes
+	documentation to imply ms dependency.
+
+	Fixes <https://savannah.gnu.org/bugs/?62062>.
+
+2022-03-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an.tmac (an*bookmark): Trivially refactor.  Now that
+	we're no longer doing arithmetic on our first argument, simplify
+	our definition.  Made possible by commit 3baf0e2f3, 23 February.
+
+2022-03-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/preconv/preconv.cpp (detect_file_encoding): Demote
+	an error diagnostic to a debugging message.  libuchardet has no
+	man page, and inspecting the source of the
+	`uchardet_handle_data` function we find that it effectively
+	returns a Boolean value (if the result of a
+	`reinterpret_cast`(!) is not `NS_OK`).  This is useless
+	information for a user-facing tool.  We're designed to muddle on
+	regardless (see preconv(1)).

+	(draw_dvi_printer::fill_next):

+2022-03-28  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[doc]: Refactor handling of "gnu.eps" file.
+
+	* doc/doc.am: Put "gnu.eps" in a Make macro, `DOC_GNU_EPS`.
+	($(PROCESSEDEXAMPLEFILES) $(PROCESSEDDOCFILES),
+	doc/webpage.html, install_doc_examples): Migrate dependency to
+	`DOC_GNU_EPS`.
+	(doc/webpage.ps): Add (missing) dependency on `DOC_GNU_EPS`.
+	(DOC_GROFF_ONLY): Drop `-I` flag; it's not necessary given the
+	following.
+	(.ms.ps): Drop `-mwww` argument from suffix rule.  A truly
+	generic ms document won't need it.
+	(doc/webpage.ps): Add target rule.  Include `-mwww` argument.
+	(doc/webpage.ps, doc/webpage.html): Pass `-I` option to
+	`DOC_GROFF` and `DOC_GROFF_ONLY` (respectively) to enable
+	location of "gnu.eps" file.  Search the build and source trees'
+	"doc" directories because the file can be generated as part of
+	the build or can come with the distribution archive.
+	(EXTRA_DIST): Drop redundant inclusion of "doc/gnu.xpm".
+	(clean_maintdoc): Add phony target to dispose of `DOC_GNU_EPS`.
+	(maintainer-clean-local): Depend on "clean_maintdoc".
+
+	* tmac/tests/pdfpic_does-not-choke-on-bad-pdfinfo-output.sh:
+	* tmac/tests/pdfpic_falls-back-to-PSPIC.sh: Update tests to look
+	for "gnu.eps" in "doc" directory of build tree.  Give generated
+	files distinguishable names so their tests can run concurrently.
+
+2022-03-23  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Add new macro `PROCESSEDDOCFILES_PS` to isolate
+	names of targets in PostScript format.  Expand this macro in
+	definition of `PROCESSEDDOCFILES` and use it to move PostScript
+	font description file dependencies of the latter and
+	`PROCESSEDEXAMPLEFILES` to the former.  (At present, the
+	dependency might seem superfluous, since those files are in the
+	source distribution, but it's conceivable that in the near
+	future, they will be produced at build time from Adobe font
+	metric files; see font/devps/generate/Makefile).  The "pic.html"
+	and "webpage.html" targets already had such a dependency because
+	of the way grohtml (pre-grohtml) works.
+
+2022-03-26  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* INSTALL.extra: Add a section on uninstalling.
+
+2022-03-23  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Create target rule for "doc/grnexampl.ps" instead
+	of relying on a suffix rule.  Explicitly depend on grn and eqn
+	executables.  Produce output using their groff flags, "-ge".
+
+2022-03-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/pdfpic.tmac (PDFPIC): Fix breakage when no temporary
+	directory environment variables are defined: actually use string
+	interpolation syntax in comparand to output comparison
+	operator.  Problem introduced by me in commits adc1999af and
+	24900cf6d, 15 February.

+	* font/devX75/devX75.am: Fix in-tree build; expand `fontdir`
+	instead of `abs_top_builddir` Make macro when defining Automake

+	into a suffix rule.
+
+2022-03-22  Ingo Schwarze <schwarze@openbsd.org>
+
+	* doc/doc.am: fix non-portable syntax in the doc/me*.me targets:
+	POSIX does not define the meaning of $< in non-suffix rules, so
+	use the portable $? instead.  This is adequate here because each
+	of these three rules has exactly one prerequisite.
+
+2022-03-22  Ingo Schwarze <schwarze@openbsd.org>
+
+	* doc/doc.am: fix non-portable syntax in the groff-man-pages.*
+	targets by using DOC_GROFF_ONLY rather than DOC_GROFF in order

+	not needed here in the first place.

+
+	[preconv]: Trivially refactor.
+
+	* src/preproc/preconv/preconv.cpp: Use diagnostic message
+	functions from libgroff where possible.  Explain in a comment
+	why we don't use `debug()`.  Boolify and rename some variables,
+	and use Boolean literals to assign to them.
+	  debug_flag         -> is_debugging
+	  invalid_warning    -> emit_invalid_utf8_warning
+	  incomplete_warning -> emit_incomplete_utf8_warning
+	Rename `expected_bytes` to `expected_byte_count`.  Except for
+	the debugging flag, these are all members of `struct
+	conversion`.
+	(get_tag_lines): Migrate to `warning()`.
+	(detect_file_encoding): Migrate to `error()` and `fatal()`, as
+	appropriate.
+	(utf8::invalid, utf8::incomplete, get_tag_lines): Don't break a
+	line in the middle of a diagnostic; doing so frustrates grepping
+	and necessarily makes an assumption about the terminal width.

+	"perhaps" comment.  I tested the surmise (setting the FSM state

+	Doctools troff interprets a `do` request, instead of ignoring it

+	(devps_font-descriptions): ...to these.  Add comments explaining
+	what they're for and why they aren't used in a build.
+
+	* font/devps/generate/Makefile: Add `outdir` variable to store
+	destination directory of font description files, and update all
+	targets that write artifacts to use this directory.  This makes
+	the targets "phony", which I don't regard as a problem since the
+	generated artifacts are kept under source control, and this
+	isn't really a user-facing script (even though it gets
+	installed).  I think there is a good chance that this will
+	become a shell script, because to avoid regressions we need to
+	generate the font descriptions using both the 229-glyph and
+	314-glyph versions of the Adobe fonts' AFM files (so that we get
+	wider glyph coverage _and_ more kerning pair data) and we need
+	to add kerning information for the ellipsis (Savannah #58897).
+	(symbolsl.afm): Revise generation process to be sensitive to
+	failure.
+
+2022-03-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* font/devps/symbolsl.afm: New file.
+	* font/devps/devps.am (EXTRA_DIST): We have long shipped
+	"symbol.afm" with the distribution archive--I don't see why we
+	don't ship "symbolsl.afm" and "zapfdr.afm" as well (metrics for
+	`SS`, the slanted symbol font, and ZDR, reversed Zapf Dingbats).
+	Like the Type 1 font descriptions themselves, this file is
+	updated only in "maintainer mode", not as part of the build.
+	Moreover, these fonts are not part of the PostScript level 2
+	base 35 fonts so their AFM files are unlikely to be readily
+	available elsewhere.

+
+	* src/roff/troff/input.cpp (get_char_for_escape_name): Recast
+	diagnostic messages to more accurately refer to escape
+	"sequence" rather than "name".  "Name" is a confusing term here,
+	given that it also applies to a group of objects sharing a name
+	space (natch): requests, macros, strings, and diversions.
+	Further, the "escape name" cited by these diagnostics is not the
+	escape function selector; that is, the character after the
+	escape character which determines how the escape sequence is to
+	be interpreted.  These diagnostics are only thrown after that
+	function is known, however, when parsing of an escape sequence
+	parameter is attempted.

+
+	* src/utils/xtotroff/Makefile.in: Delete relic of old build
+	system.  Also, it had a bug: it generated X11 output device
+	'DESC' files with a "unitwidth 10" directive even for the "-12"
+	devices, which is not correct (the in-tree DESC files we've been
+	shipping for years were nevertheless correct, apparently fixed
+	by hand by James Clark in groff 1.07 [March 1993]).

+	font description files.  Be sure to set the correct "unitwidth"
+	for the "-12" devices.  Add new dependency-only rule

+	for convenience (and future expansion to devps and devlj4).
+
+	* FOR-RELEASE: Document existence of

+	[man,mdoc,me]: Revise hyphenation localization.

+	terrible fit for groff's font family and style-combination
+	functionality, and is inflexible in the face of font selection
+	requests and escape sequences within the example region.  (One
+	either needs to know the names of the fonts available on the
+	output device, or suffer the indignity of mixed constant-width
+	and proportional typefaces.)  Relatedly, drop groff-specific
+	font remapping requests.
+	(EX, EE): Ignore definition if GNU troff is the formatter.  Drop
+	font family manipulation.  Drop specialized logic for groff's
+	DVI output device.
+
+	* tmac/an.tmac (initialization): Resurrect font remapping

+

+	Stop shelling out to create, and then sourcing, a temporary file
+	just to obtain the value of an environment variable.  groff
+	already has the `\V` escape sequence for that purpose (it's even
+	safe!).  Check that the value of $GROFF_PDFPIC_NOSPACE is a
+	valid numeric expression before assigning it to a register.
+	Trivially, use '=' instead of '==' as an equality operator.
+	*roff languages do not use '=' as an assignment operator, and I

+
+	* tmac/e.tmac (u): On nroff devices, bracket the first argument
+	with \(ul (underline rule) special character escape sequences.
+	{In plain language, '.u "like this"' renders "_like this_".}
+
+	I regard this as a cosmetic and semantic improvement; since the
+	quarter-em vertical motions used in troff mode were ignored in
+	nroff mode, the effect was not underlining but a sort of
+	strike-through, visible only at spaces in the argument.  The use
+	of this macro was thus invisible in nroff output if no spaces
+	were present in the argument.  This is probably the best we can
+	do without a fatter interface to terminal device capabilities.

+	(initialization): Migrate macro appendments to appropriate
+	definitions.  Two cases...
+	(SH, SS): ...were straightforward.
+	(initialization): Another (for the man page title) was poorly
+	placed when appended to the `TH` macro, skipping over the page
+	header.  Move it instead...
+	(PT): ...here.  But to keep this bookmark from being generated
+	on every page of a document, we need a new variable
+	`an*was-TH-bookmark-emitted` which is tested here and assigned
+	once one bookmark corresponding to a `TH` call has been written.
+	(TH): Initialize `an*was-TH-bookmark-emitted` to zero.
+	(SS): Write the bookmark _before_ the subsection heading text.
+	(initialization): Drop short-lived `BM` register.  It seems
+	harmless to unconditionally include bookmarks in PDF output.  A
+	PDF tool can strip them out if they're not desired, and viewers
+	seem capable of minimizing or reducing the navigation pane (if

+
+	Implement PDF bookmark support for man pages.  Limitation: A
+	{sub}section can only be bookmarked if it is specified in the
+	arguments to the `SH` or `SS` requests, not on the next line in
+	an input trap.  Thanks to Deri James for providing the
+	fundamentals (blame me for any weird bits).
+
+	* tmac/an.tmac (an-prepare-page-title): Define a new string,
+	`an*page-ref-string`, which is the man page's own reference
+	{such as "groff(1)"} without any abbreviation, ellipsis, or font
+	selection or italic correction escape sequences.
+	(SS): Define a new string, `an*subsection-heading`, storing the
+	macro arguments (if any).  These could contain font selection
+	escape sequences, for instance, a fact that becomes important
+	later.
+	(initialization):
+	- Recognize `BM` register to enable PDF bookmarks (only on the
+	  'pdf' output device); defaults on.  Recognize `BN` register to
+	  set a base level/depth for the bookmarks; this is to ease
+	  embedding of man pages in other PDF documents that already use
+	  bookmarks.  The default is 0.  The registers are not yet
+	  documented.
+	- If the output device is 'pdf' and bookmarks are enabled, set
+	  `PDFOUTLINE.FOLDLEVEL` and `PDFHREF.VIEW.LEADING` registers
+	  {recognized by 'pdf.tmac'}.  Append to `TH`, `SH`, `SS` to get
+	  the `an*page-ref-string`, `an-section-heading`, and
+	  `an*subsection-heading` bookmarks in the document at the
+	  applicable levels.
+
+	* tmac/mdoc/doc-common: Add straw-man implementation--it doesn't
+	support the `BM` and `BN` configuration parameters yet.  (This
+	is enough to get bookmarks for the groff_mdoc(7) page to
+	correctly appear in the new 'groff-man-pages.pdf' document.)
+	(Dt, Sh, Ss): If the output device is 'pdf', place bookmarks in
+	the document at levels 1, 2, and 3.

+
+	* doc/doc.am (doc/groff-man-pages.pdf): Drop `-rU0` option (it's
+	unnecessary since we don't yet have PDF hyperlink support in
+	this document).  Add `-rC1` option to enable continuous page
+	numbering.
+	(doc/groff-man-pages.utf8.txt): Drop `-rC1 -rU1`.  Continuous
+	page numbering is superfluous since page numbers are not shown
+	in continuous rendering mode.  Stop turning on OSC 8 defaults;
+	we don't know if the document will be viewed with a supporting
+	pager+terminal combination, and further we don't yet have a
+	mechanism for making `MR` man page cross references internal to
+	the document when they indicate groff man pages.

+
+	[man pages]: Ship compilations in UTF-8 text and PDF.
+
+	Localization support and the resolution of Savannah #61266 have
+	made it practical to batch-render all of groff's man pages as a
+	single giant document.  Provide PDF and UTF-8 text (with ECMA-48
+	escape sequences, but not the italic attribute or OSC 8
+	sequences).
+
+	Reasons for this addition include: {1} it is now possible,
+	whereas I don't believe it was in any previous groff release;
+	{2} many people still don't realize how much more pleasant
+	reading typeset man pages can be (while a subjective assessment,
+	I'm not alone[1]); {3} providing these forms permits full-text
+	searching of groff's entire man page corpus via the PDF viewer
+	or a pager like "less -R", the latter without sacrificing the
+	style variations of the text that aid the reader to comprehend
+	the material; {4} sentimentally, it honors the 50th anniversary
+	of the first Unix manual (dated 3 November 1971)
+	<https://www.bell-labs.com/usr/dmr/www/1stEdman.html>.
+
+	* doc/doc.am (PROCESSEDDOCFILES): Add
+	'doc/groff-man-pages.{pdf,utf8.txt}'.
+	(GROFF_MAN_PAGES{1,2,3}): Add new macro storing names of all man
+	pages generated in the build tree.  Motivate the reason for 3

+	(GROFF_MAN_PAGES_ALL): Add convenience macro for use in

+	[man]: Commit c64fd60dff was not quite cooked.  The localized
+	strings (in English) for the manual section titles need to be
+	set at every document load (i.e., when `TH` is called), but only

+
+	* tmac/pdfpic.tmac (@abort): Rename to `pdfpic@error`.  This is
+	an auxiliary package, and something else could very well step on

+	(pdfpic@error): Stop aborting; simply report an error.  It's up
+	to the user how serious `PDFPIC` macro problems are.  As noted
+	in a comment, the user can easily `am pdfpic@error` to tack an
+	`ab` request onto the end of its definition.  Always report
+	input file name and line number.  Replace "[PDFPIC]" prefix with
+	the name of the macro file complaining, to make it easier for
+	groff non-experts to find.
+	(PDFPIC): Return upon errors.  Recast diagnostic messages.  Stop
+	implying that we perform any sort of probing test of file type
+	{there's no telling what pdfinfo(1) will say}.  Apply new
+	'stringdown' request so that we accept '.pdf' file name
+	extension in any lettercase.  Test file argument for existence
+	before proceeding (acknowledge TOCTTOU exposure).  Skip file if
+	pipeline returned a non-zero exit status or the registers into
+	which we extract the height and width are undefined (indicating
+	failure of a temporary file to be created or read).  Reject
+	files with non-positive image width or height reported by
+	pdfinfo.  Validate `width` and `height` arguments, if given,
+	rejecting non-positive values.

+	(table::init_output, table::compute_expand_list,
+	table::compute_separation_factor):
+	- Move `entry_list->set_location()` calls to more auspicious
+	  locations.
+	- Replace "around line X" language in diagnostic messages with a
+	  more idiomatic, and less embarrassing, simple report of an
+	  integer.
+	(table::init_output):
+	- Add `entry_list->set_location()` call right before emitting
+	  diagnostic about a table row not fitting on a page.
+	- Turn off eqn(1) delimiters when emitting diagnostic about a
+	  boxed table not fitting on a page (necessitating `.TS H`
+	  support), using new NOP_NAME-based end macro to achieve this
+	  inside a macro definition.
+	(table::compute_expand_list): Suppress issue of too-wide table
+	diagnostic when the `EXPAND` table flag is set (corresponding to
+	the `expand` region option), because other code already emits
+	diagnostics in this case.

+

+
+	* src/preproc/tbl/table.cpp (compute_expand_width): To properly
+	warn if a table is too wide to fit between the indentation and
+	the right margin, we need to compute its column widths including
+	those eligible for expansion via the 'x' column modifier; we
+	cannot use the same expression that we do to determine the
+	amount of space we have to distribute among the expanded
+	columns.  Iterate through columns again (the function was
+	already doing so twice), once to potentially produce the
+	warning, and then as before to distribute any available width.
+	In other words, warnings were only being emitted for too-wide
+	tables where one or more columns used the 'x' modifier.

+
+	* tmac/unicode.tmac: Drop.  It was originally added in 2005 to

+	Its purpose has wandered over the years; most recently to map
+	the Basic Latin ("ASCII") hyphen-minus, apostrophe, and grave
+	accent to special characters (and thus ultimately to the General
+	Punctuation block).  But this is unnecessary since the font
+	descriptions for devices with the `unicode` property can provide
+	this information, and anyone who wants to alter the mappings can
+	change either font description files, output device macro files,
+	or troffrc; or add `char` requests to their macro packages or

+	* tmac/tmac.am (TMACNORMALFILES): Stop shipping it.

+	I disagree with the reasoning (whether these glyphs are "too

+	which we have no control), but this mapping happens in a
+	completely different part of the source tree,
+	src/libs/libgroff/glyphuni.cpp.
+
+	* font/devhtml/R.proto:
+	* font/devutf8/R.proto: Add mappings for the five Basic Latin

+	* tmac/tty-char.tmac: Drop redundant logic.  We don't need to
+	source the `cp1047` or `latin1` files here; `troffrc` will
+	already have loaded `tty` for us, which loads whichever applies.
+
+2022-01-14  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Separate concerns better; stop re-generating plain
+	text and HTML documents when the 'doc' target is updated; these
+	are already handled by the 'build_infodoc' target.
+	(build_infodoc): Use existing phony targets for plain text and
+	HTML output files instead of repeating filename literals.
+	(doc_all): Remove those same two phony targets from this one's
+	dependencies.
+
+2022-01-14  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/roff/troff/input.cpp: Rename `eoi_macro_name` to
+	`end_of_input_macro_name`.  It's long, yes, but better parallels
+	`blank_line_macro_name` and `leading_spaces_macro_name`.  It is
+	not used in lengthy expressions and furthermore clarifies the
+	meaning of the nearby function name `eoi_macro` in one use.

+	[docs]: Be more careful with control characters when they are
+	word-initial in filled text lines.  The idea is to prevent
+	baffling surprises if a sentence is recast in a text editor, and
+	a word beginning with a dot or neutral apostrophe is reflowed
+	onto the beginning of the next input line--suddenly it is parsed
+	as a control character.  Based on a patch by Bjarni Ingi

+
+	* tmac/{cs,de,it,sv}.tmac: Localize the man(7) package's HY
+	register.
+
+	* tmac/{cs,de,fr,it,sv}.tmac: When localizing the ms(7) package,
+	use mode "2" instead of "3": the 'hy' request complains of
+	contradictory hyphenation modes if "3" is used (the semantics of
+	the hyphenation mode are complex and non-orthogonal; see
+	groff(7) or our Texinfo manual).
+
+	* tmac/{cs,de,en,fr,it,sv}.tmac: If the one language-independent
+	hyphenation bit (don't hyphenate just prior to a page location
+	trap) is set, preserve it; this way a system's troffrc or a
+	macro package can set it and it will not get turned off by the
+	localization package, which for best results should be loaded
+	after any full-service package (and any auxiliary package
+	requiring localized strings, though none are yet distributed

+
+	[libbib]: Refactor index header checking.
+
+	* src/libs/libbib/index.cpp: Move more header validity checks...
+	(index_search_item::load): ...from here...
+
+	(index_search_item::check_header): ...to here.  Test all size
+	values in header for negative values (never valid) before
+	proceeding.  (These data could be changed to unsigned integer
+	types in the file format, but that would require bumping the
+	file version.  That in turn would make indexes generated with
+	groff 1.23 unusable on systems running older groffs and, perhaps
+	worse, would make groff 1.23 reject index files produced by
+	older groffs.  On the other hand, the regeneration of index
+	files should be, for those who use them, a common activity, and
+	as long as the original database files are kept intact, it seems
+	likely that most people, given modern machines, won't even
+	notice a slowdown in document generation when refer(1) and
+	friends fail to open the indices and fall back to full-text
+	searches of the originals.  So we could still consider revising
+	the file format before the groff 1.23 release.)
+
+	* src/libs/libbib/index.cpp (index_search_item::load):
+	Explicitly perform widening conversion from signed `off_t` value
+	{from a stat(2) buffer} to an unsigned integer; quietens
+	compiler warning about comparison between integers differing in
+	signedness.
+
+2022-01-05  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* configure.ac (AC_CHECK_HEADERS): Expect stdbool.h, since we

+2022-01-05  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[libbib, libgroff, indxbib]: Slightly refactor.
+
+	Also, it's silly to test even numbers > 2 for primality.  Stop.
+
+	* src/include/lib.h: Include `stdbool.h` since this header file
+	is used for both C and C++ code.
+
+	* src/include/lib.h (is_prime):
+	* src/libs/libgroff/prime.cpp (is_prime): Boolify.  Return
+	Boolean instead of integer literals and demote return type to
+	`bool`.  Include `assert.h` and add assertion to reject
+	mathematically offensive input.
+
+	* src/libs/libbib/index.cpp
+	(index_search_item::read_common_words_file): Test only odd
+	numbers for primality.
+	* src/utils/indxbib/indxbib.cpp (main): Same.  Since the number
+	comes from user input, make it (a potential hash table size) odd
+	first.
+
+2022-01-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[man]: Internationalize and localize.
+
+	* tmac/an.tmac (TH): Indirect predefined manual section titles
+	through new strings `an*section[1-9]` so that they can be
+	localized.
+	(initialization): Give these strings English defaults.
+	(TH): Move `ss` request from here...
+
+	* tmac/en.tmac: ...to here.  It's not the man(7) package's
+	business what the inter-word and inter-sentence spacing values
+	are.  Also, having the correct[disputed] inter-sentence spacing
+	value for English in its localization file restores it for the
+	benefit of multi-lingual documents (mainly roff applications
+	other than man(7)).
+
+	* tmac/{cs,de,fr,it,sv}.tmac: Supply translations for the manual
+	section titles; these were done by a monoglot American employing
+	Google Translate, so those scandalized or running into howlingly
+	wrong locutions are warmly invited to submit corrections.
+
+	* tmac/trans.tmac: Load localized strings.

+
+2022-01-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/utils/grog/grog.pl: Handle auxiliary macro package
+	arguments correctly.
+	(process_arguments): Don't append the argument to the '-m'
+	option to the command line; requested macro packages have
+	dedicated logic.
+	(construct_command): When iterating through requested package
+	list, assume each element is an auxiliary package unless it
+	matches an element in the list of main packages.  If the
+	assumption holds, append the package name to a new list,
+	`auxiliary_package_argument` (prefixed with '-m').  Push this
+	list onto the command line after any main package.
+
+	Also rename `$selected_main_package` to `$main_package` for
+	brevity, and drop unused global lists `m` and
+	`supplemental_package`.

+
+2022-01-03  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[me]: Drop unnecessary code.  Apart from being superfluous, it
+	prevented a user-defined value of the `sx` register from being
+	applied to the first footnote marker interpolated, a subtlety
+	that escaped my notice because the first footnotes in our
+	"meref" and "meintro" documents are not numeric, but symbolic,
+	and their markers occurred on lines with vertical space above
+	and below.  (The bug was further masked by an otherwise
+	redundant redefinition of the `*` string inside the `)f` macro.)
+
+	* tmac/e.tmac ()f, +c): Stop redefining footnote marker string
+	`*` after updating the automatic footnote number; its
+	interpolation is already backslash-protected.
+	()d, pd): Stop redefining delayed text marker string `#` for an
+	analogous reason.
+	(initialization): Drop unneeded `_*` and `_#` strings.
+
+	Thanks to Robert Goulding for his feedback and patience.  See

+
+2022-01-03  G. Branden Robinson <g.branden.robinson@gmail.com>

+
+	[me]: Revise `n1` and `n2` interface and behavior.
+
+	There were several bugs in the previous implementation.
+
+	* tmac/e.tmac (po): Issue diagnostic if an attempt is made to
+	set the page offset to a negative value.
+
+	(n1): Accept new optional "C" argument to behave more (but not
+	exactly) like roff(1), as the formerly-recognized "c" argument
+	to `n2` did.  If present, the line length is reduced by the same
+	amount (in new interface register `no`) as the line number field
+	to preserve the overall line length.  Save the previous line
+	length in internal register `_l` and set a flag, stored in `?N`,
+	indicating this reduction.  Otherwise, the macro expects to be
+	able to reduce the page offset to accommodate the line number.
+	If it cannot (for example, with the zero page offset default
+	used by nroff output devices), see above re: the `po` macro.
+
+	(n2): Cache the last line number that may have been output,
+	instead of the current one, so that we can operate on it
+	consistently with user expectations.  Do this earlier, and
+	rename this macro-local variable from `_ln` to `_n` so that we
+	don't need groff's `do` request to operate on it.  Drop
+	recognition of "c" as an optional second argument.  If turning
+	off line numbering: if the line length was shortened (`?N`)
+	restore the saved value and delete `_l` register; otherwise,
+	reverse the change to the page offset.  Delete `_n` register.
+
+	(initialization): Assign `\w'0000'u` to `no` register; this was
+	previously hard-coded in `n1` and `n2`.  Initialize `?N` with 0.
+
+	* doc/meref.me.in (roff Support): Update to reflect interface
+	changes and describe behavior more accurately.
+
+	* doc/meref.me.in (Summary):

+
+	[tbl]: Slightly refactor table format column modifier `p` and
+	`v` validation.
+
+	* src/preproc/tbl/main.cpp (process_format): Make code terser by
+	introducing references to `list->point_size` and
+	`list->vertical_spacing`.  Doing this requires a new scope
+	{because a switch case isn't one} so add it, without updating
+	indentation for this commit.  When complaining of out-of-range

+
+2021-11-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[tbl]: Improve diagnostic messages.
+
+	Revise diagnostic messages generally to use terminology
+	consistent with the recent rewrite of tbl(1), identify a
+	contextual token when possible, and communicate more helpfully.
+
+	* src/preproc/tbl/main.cpp (process_options): Tell the user
+	which region option is missing a closing parenthesis or cannot
+	accept an empty argument.  Refer to region options as such, not
+	simply "options" (so they can't be confused with command-line
+	options).  Say that input is "invalid" instead of "bad".
+	(process_format): Say "table format specification" instead of
+	just "format".  Say "column classifier" instead of "format".
+	When a column modifier is missing an argument or a closing
+	parenthesis, identify it and refer to it as a "column modifier"
+	instead of omitting context.  Inform user that arguments to `p`
+	and `v` column modifiers must be "(optionally signed) integer"s,
+	not "numbers", lower these diagnostics' levels from error to
+	warning, and indicate that the modifier is ignored.  Clarify
+	diagnostic when extra characters trail `.` at the end of a table
+	format line.
+	(process_data): Say "table entry" instead of "data entry" when
+	discarding an excess one.
+	(process_table): Say we're giving up on "this table region", not
+	this "table", particularly since any table continuations (.T&)
+	are ignored.
+

+
+	[tbl]: Fix call to `getopt_long()`.

+
+2021-11-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+

+
+	[tbl]: Fix code style nits.
+

+	(struct input_entry_format, input_entry_format::debug_print,
+	process_format): Boolify.  Demote and rename `int`s
+	`last_column` and `equal` to `bool`s named `is_last_column` and
+	`is_equal_width`.  Assign them Boolean literals.
+	(process_format): Boolify.  Demote `have_expand`, `got_format`,
+	and `got_period` from `int` to `bool`.  Use Boolean literals in
+	assignments thereto.
+	(process_options): Swap order of null pointer comparison when a
+	typo or thinko could lead to lvalue assignment.
+	(process_data): Boolify.  Demote `give_up` from `int` to `bool`.
+	Demote and rename `int` `row_comment` to `bool`
+	`seen_row_comment`.  Use Boolean literals in assignments
+	thereto.
+	(main): Use standard C library symbols `EXIT_SUCCESS` and
+	`EXIT_FAILURE` with `exit()` calls instead of `0` and `1`.

+
+2021-11-20  G. Branden Robinson <g.branden.robinson@gmail.com>

+

+
+	[tbl]: If "nowarn", suppress table row warning.
+
+	* src/preproc/tbl/table.cpp (table::init_output): Bracket the
+	generated groff code that emits a warning if a table row
+	overruns a page location trap (usually, is too long to
+	vertically fit on the page) in a test for whether the "nowarn"
+	region option was given, so that this warning is suppressed as
+	well when that option is used.
+	* src/preproc/tbl/tbl.1.man (Region options): Document new
+	"nowarn" behavior.
+
+	{"nokeep" also suppresses this warning, for a different reason;
+	no diversion is created to hold the table row, so its vertical
+	size does not exist to be compared to the distance to the next

+
+2021-11-13  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/tbl/table.cpp (table::do_vspan): Fix code style

+	when a typo or thinko could lead to lvalue assignment.  Break a
+	series of 6 and-ed assertion predicates into separate `assert()`
+	calls--sure to be less maddening for anyone who has to debug
+	such a contingency.  Clarify comment since C++98 didn't yet have
+	`nullptr`.

+
+2021-11-13  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[m4]: Clean up test(1) usage.
+
+	Get rid of string (non-)nullity tests and comparisons involving
+	concatenation with garbage (usually "x").  Even the GNU Autoconf
+	manual's shell portability material doesn't recommend this.  It
+	must be either a bodge cooked up by shell programmers who
+	couldn't remember to quote variable expansions, or a workaround
+	for shells of such poor quality that they defied the odds and
+	decayed out of usage or got fixed.
+
+	Instead, use double quotes (only where necessary).  Test for
+	non-empty strings with "test -n" and empty strings with "test
+	-z".  Stop quoting literal comparands that obviously have no
+	shell metacharacters in them.
+
+	* m4/groff.m4 (GROFF_PRINT, GROFF_PROG_YACC, GROFF_PERL)

+
+2021-11-12  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_TEXI2DVI): Add dependency on
+	`GROFF_MAKEINFO` macro.  Rewrite to also test `MAKEINFO`
+	variable, which is empty if the `makeinfo` command is not
+	installed or too old.  Consequently ignore `texi2dvi` if is too
+	old without having to do a version check (since it and
+	`makeinfo` are distributed together, both being part of GNU
+	Texinfo).
+
+	* doc/doc.am (.texi.dvi, .texi.pdf): Update error message to
+	indicate that `texi2dvi` is _either_ missing or too old.
+
+2021-11-12  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_MAKEINFO): Stop throwing a warning if the
+	installed `makeinfo` is old but the distributed Info manual is
+	up to date.  This is not a configure-time problem; the user will
+	be notified when they run 'make' if they modify doc/groff.texi,
+	or if they run 'make doc' (which has required a TeX installation
+	for years).  Empty the `MAKEINFO` variable immediately if a
+	too-old version is detected.  Drop needless `AC_SUBST`itution of
+	the detected `makeinfo` version.
+
+2021-11-12  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_HTML_PROGRAMS): Clarify message; it is only

+	Texinfo manual in HTML format.)
+
+2021-11-11  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[build]: Drop `BUILD_INFODOC` symbol.  Ship manual in GNU Info,

+	(MOSTLYCLEANADD): Drop unused variable.
+	* configure.ac: Drop `AM_CONDITIONAL([BUILD_INFODOC]...`.
+	* doc/doc.am (EXTRA_DIST): Rearrange shipment of our Texinfo
+	manual source files to precede all of the generated forms, for
+	clarity.  Drop all `BUILD_INFODOC` conditionals.  Make
+	`build_infodoc` phony target depend on plain text, GNU Info, and
+	HTML forms of Texinfo manual unconditionally.  Also drop unused
+	variables `groffinfodir`, `groffpdfdir`, and `texi2dvi_missing`.
+	(EXTRA_DIST, MAINTAINERCLEANFILES): Add Info form of manual.
+	Drop glob pattern attempting to match the segments that
+	`makeinfo` breaks it into.  It isn't necessary for
+	MAINTAINERCLEANFILES.
+	(EXTRA_DIST, MAINTAINERCLEANFILES): Add text form of manual.
+	(EXTRA_DIST, MAINTAINERCLEANFILES): Add HTML form of manual.
+	(dist-hook): Depend on new (phony) target `dist-info-bits`.
+	(dist-info-bits): Look for the info document in the build
+	directory, then the source directory.  (It could be in either
+	place depending on whether the build from a Git working tree is
+	being done in or out of a separate build directory.)  When
+	found, copy the segments to the assembly area for the
+	distribution archive.
+	(install_infodoc): Refactor.  Remove any groff info files from
+	the destination info directory using a shell glob directly
+	instead of a partly redundant ls(1) command substitution.
+	Similarly, use a shell glob to cp(1) the info files (including
+	any matched segments) to the destination info directory before
+	running `install-info`.  (In this process I learned that
+	`install-info` doesn't "install" anything; instead, it
+	{de-}registers info files with their top-level catalog.)
+
+2021-11-11  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am (.texi.txt, .texi.html): Reorder pattern rules to

+	[libgroff]: Fix missing colon in diagnostic messages.
+

+
+	[libgroff,grops]: Slightly refactor.
+
+	* src/devices/grops/ps.cpp: Explicitly preprocessor-include
+	"lib.h" since we use the `PI` symbol it defines.
+
+	* src/include/lib.h: Add inclusion guard.  Wrap only `extern "C"
+	and its braces in preprocessor conditionals, so that prototypes
+	are present in the header even for C language code that
+	#includes this header.  Add `static` storage class to `PI`
+	symbol to avoid redefinition errors from the linker.
+
+	* src/libs/libgroff/iftoa.c (if_to_a):
+	* src/libs/libgroff/itoa.c (i_to_a, ui_to_a): Add `const` type
+	qualifier to function definitions for agreement with prototypes
+	in "lib.h".  Drop local copies of prototypes.
+
+2021-11-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[libgroff]: Centralize definitions of {U,}INT_DIGITS.
+
+	* src/libs/libgroff/iftoa.c:
+	* src/libs/libgroff/itoa.c: Move definitions of `INT_DIGITS` and
+	`UINT_DIGITS` from here...
+	* src/include/lib.h: ...to here.
+
+	* src/libs/libgroff/iftoa.c:
+	* src/libs/libgroff/itoa.c: Preprocessor-include "lib.h".  This
+	revealed missing guards around `extern "C"` declarations, so...
+
+	* src/include/lib.h: Add them where necessary.
+
+2021-11-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an.tmac (OP): Fix code style nits.  Don't quote macro
+	arguments unnecessarily.  Use consistent backslashing.  Use
+	groff font escape sequence syntax.  Use adjustable non-breaking
+	space escape sequence instead of a non-adjustable one.
+	Parenthesize numeric expression for better readability.
+
+2021-11-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[libgroff]: Make allocator replacement optional.  Switch it
+	off by default, relying on C++ runtime new/delete support.
+
+	* configure.ac: Call new `GROFF_USE_GROFF_ALLOCATOR` m4 macro.
+	Use `AM_CONDITIONAL` to set Automake variable
+	`USE_GROFF_ALLOCATOR` if appropriate.  Report whether the
+	allocator is used in configure script output summary.
+	* m4/groff.m4 (GROFF_USE_GROFF_ALLOCATOR): Define new macro to
+	collect user preference.  The default is off.
+	* src/libs/libgroff/libgroff.am (libgroff_a_SOURCES): Build and
+	link new.cpp only if we are to `USE_GROFF_ALLOCATOR`.
+
+	* NEWS: Add item.
+
+2021-11-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+

+	no system tmac prefix is found, instead of leaving the ellipsis
+	hanging.
+
+2021-11-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_TMAC): Use separate shell variable for
+	`AC_MSG_RESULT()` content since the human-readable string we
+	populate it with in the empty case is not appropriate for later
+	`AC_SUBST()`-itution.  Problem introduced by me in commit
+	19670348, 31 October.
+
+2021-11-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/tmac.am (MOSTLYCLEANFILES): Remove `$(TMACMDOCFILES)`.
+	This variable, formerly named `TMACMDOCSTRIPFILES`, should not
+	be used in a clean target because its contents are (no longer)
+	generated files.  Problem introduced by me in commit 24602f42, 4
+	July (only noticeable in within-source-tree builds).

+
+	[libgroff,pic]: Check `strdup()` return value.
+
+	* src/libs/libgroff/font.cpp (struct text_file): Add `fatal()`

+	(text_file::fatal): Implement it.
+
+	* src/libs/libgroff/font.cpp (font::load_desc):

+2021-11-08  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/libs/libgroff/error.cpp (do_error_with_file_and_line):
+	Revise to eliminate `fprintf()` calls, which might perform
+	dynamic memory allocation, rendering this function unsafe to
+	call after memory allocation failures.  Since this function is
+	near the top of our diagnostic output call stack, that would be
+	unfortunate.  `errprint()` does not use dynamic allocation, nor
+	do the `i_to_a()` and `ui_to_a()` functions it calls to format
+	integers.
+
+2021-11-08  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* configure.ac: Add `strdup` to AC_CHECK_FUNCS since we are
+	using it and the whole point of libgroff's `strsave()` was to
+	get along without it.  But `strdup` has been standardized in
+	POSIX for 20 years (SUSv3, POSIX:2001) and is on its way into
+	ISO standard C (N2353) and C++ (P2391R0) as well.
+
+2021-11-08  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/libs/libgroff/strsave.cpp (strsave): Call `strcpy()` only

+	Ingo Schwarze.
+
+2021-11-07  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/libs/libgroff/fontfile.cpp (font::open_file): Don't open
+	user-specified font file names with slashes in them; i.e., don't
+	traverse directories outside the configured font path.  Also
+	refuse to open the file if the `sprintf()` used to construct its
+	file name doesn't write the expected quantity of bytes to the
+	destination buffer.

+	tag}, then typeset the URI as part of the indented paragraph.

+

+	invalid argument.  Emit a diagnostic error if the argument we're
+	given is invalid, and immediately end the diversion we just
+	opened.
+
+2021-11-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+

+
+2021-11-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/tbl/table.cpp (table::add_entry): If we see a '\^'
+	entry on the first row of a table, it's invalid, but we need to
+	create an empty entry in its place.  Otherwise, someone can put
+	another '\^' right below the one on the first row, creating a
+	reference to a nonexistent table entry and provoking a SEGV.
+	Issue an error diagnostic (distinct from the one in
+	`do_vspan()`), create the entry, and skip `do_vspan()` (given a
+	'^' in a first-row definition, it issues an error diagnostic and
+	returns early, which suffices).  Problem appears to date back to
+	groff 1.02 (June 1991) at the latest.

+
+	* src/libs/libgroff/font.cpp (font::load): Include more

+	  - When a kern pair's amount is missing or invalid, report the
+	    name of the kern pair.
+	  - When someone tries to declare the first entry in the charset
+	    section as an alias, report the glyph name.
+	  - Identify the token for the unnamed character if an attempt
+	    is made to alias it.
+	  - When an out-of-range character type is applied to a glyph,
+	    name the glyph.
+	(font::load_desc): Same.
+	  - Drop redundant zero initialization of `res`.
+	  - Check all directives that take basic units for positive
+	    values, adding `res`, `unitwidth`, `paperwidth`, and
+	    `paperlength`.  Update this diagnostic to demand positive,
+	    not nonnegative, values.
+	  - When the font count is long in a `fonts` directive, report
+	    how many font names were declared (and thus expected).  (If
+	    the count is short, the next line is read for a font name,
+	    like 'tcommand' in our devutf8/DESC.)
+	  - When interpreting a `papersize` directive, throw an error
+	    and return false if `res` has not yet been encountered,
+	    since it is used in subsequent computations.
+	  - When a paper format cannot be determined, report the
+	    original declared value from the DESC file.  Use `strdup()`
+	    to save it since it gets clobbered by the resolving process.
+	    `free()` the saved string when we're done, regardless of
+	    error condition.
+
+	* doc/groff.texi (Device and Font Files):
+	* man/groff_font.5.man (DESC file format): Document additional

+	[troff]: Handle special character escape sequences that map to
+	basic Latin glyphs in device control escape sequences
+	consistently among output devices.
+
+	* src/roff/troff/input.cpp (encode_char): Rearrange
+	conditionals.  This is the logic that puts the "whatever" within
+	a \X'whatever' escape sequence into GNU troff's intermediate
+	output.  Handle adjustable and nonadjustable space escape
+	sequences ("\~" and \ ") first.  Then, if the token is a special
+	character escape sequence, retrieve its "contents" (glyph name).
+	Move the basic Latin mapping for the seven glyph names '-',
+	'aq', 'dq', 'ga', 'ha', 'rs', and 'ti' here, before checking
+	whether the device description issued the
+	'use_charnames_in_special' directive.  This way, the 'html' and
+	'xhtml' output devices can straightforwardly embed these basic
+	Latin characters in device control escapes (notably, "html:",
+	for which the present convention is to follow the this tag
+	immediately with a literal HTML URI, complete with `<a href>`
+	element syntax).  If the special character is none of these and
+	we should 'use_charnames_in_special', proceed as groff 1.22.4
+	and earlier did.  This is a behavior change, as was my addition
+	of this translation mechanism in the first place, so...

+
+	* src/preproc/eqn/eqn.am (neqn): Simplify: drop removal of
+	target prior to overwriting it; any system we can build groff on
+	should have a shell that implements the clobbering semantics of

+	(src/libs/libgroff/version.cpp): Drop progress-reporting `echo`

+	instead of `echo` to build the file, and create a temporary file

+	with `$(AM_V_GEN)`.

+
+	* font/devpdf/devpdf.am: Build more quietly.
+	(font/devpdf/enc/text.enc, font/devpdf/map/symbolmap,
+	$(DEVPDFFONTMAP_1)): Prefix all rule commands with
+	`$(AM_V_at)`; since these are all `mkdir`s and `cp`s, I reason
+	that little can go wrong with them that won't be disclosed by
+	these tools' own diagnostic messages, so they are insignificant
+	from a perspective of build progress.
+
+2021-10-21  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Build more quietly.
+	(doc/examples.stamp): Prefix all rule commands with

+	completely silent by default.
+	(doc/groff.info, .texi.txt): Prefix directory creation with
+	`$(AM_V_at)` and `makeinfo` command with `$(AM_V_GEN)`.
+	(.texi.dvi, .texi.pdf): Prefix directory creation with
+	`$(AM_V_at)` and `makeinfo` command with `$(AM_V_GEN)`.  Send
+	diagnostic message to standard error if `texi2dvi` is
+	unavailable.
+	(.texi.html): Prefix directory creation with
+	`$(AM_V_at)`.  Two HTML versions are produced, in split and
+	unsplit versions; prefix one `makeinfo` command with
+	`$(AM_V_GEN)` and the other with `$(AM_V_at)` so that only one
+	message is produced.
+	(gnu.eps): Drop useless/noisy `echo` command.  Prefix copy
+	operation with `$(AM_V_at)`.  Send diagnostic messages to
+	standard error if there are problems with the Netpbm tools.
+
+	(MOSTLYCLEANFILES): The `mostlyclean` target was leaving a file,
+	`groff.info-3`, behind in the build tree.  At some point our
+	Texinfo manual grew beyond earlier expectations.  Use a glob
+	`[0-9]` instead (giving a hostage to fortune that `makeinfo`
+	will never split our manual into more than nine chunks).
+

+
+	* arch/misc/misc.am:
+	(arch_shdeps_sh): Pull file name into a new variable.

+
+2021-10-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[nroff]: Support groff's -R flag to run refer(1).
+
+	There's no reason not to support calling `refer` with nroff-mode
+	documents; typographically, it's less demanding than tbl(1).
+	GNU troff(1) supports an incompatible `-R` flag to suppress the
+	reading of troffrc{,-end} files, but this is likely not the `-R`
+	that users will want--it is most useful for troubleshooting
+	troff, and nroff already unconditionally loads a macro file
+	{tty-char.tmac}.

+
+	Include <config.h> before any standard headers.

+	[andoc,man,mdoc]: Fix Savannah #61266.  Resolve problems in

+

+	traps alongside others.
+
+	* tmac/an.tmac (an-end): Only perform flush and "manual" page
+	footer placement if in continuous rendering mode, since this
+	macro is not only called by a trap placed only in continuous
+	rendering mode, but also by andoc when changing macro packages.
+	Unconditionally remove the `an-header` trap since the next
+	document might be using a different macro package.
+
+	* tmac/mdoc/doc-common: In initialization, set flag indicating
+	that manual header placement will be required.
+	(Dt): Call `doc-setup-header` (which sets up several types of
+	trap) unconditionally, and break the page if the vertical
+	drawing position is anywhere but at the top.
+	(Os): If the package has just been initialized, call
+	`doc-header` to force the page header to be written.
+	(doc-end-macro): Remove `doc-header` trap since the next
+	document might be using a different macro package.  Break the
+	page.  Set flag indicating that manual header placement will be

+	trap, the `doc-setup-header` implementations are now identical.
+
+	Refactoring is needed: some macros and registers have misleading
+	names, there is some code duplication in mdoc, and some of the
+	trap management problems are solved in slightly different ways
+	in man(7) and mdoc(7), perhaps unnecessarily.  We also need some

+	[grotty]: Add OSC 8 hyperlink support.
+
+	* src/devices/grotty/tty.cpp: Do it.  Define `OSC` (Operating
+	System Command) and `ST` (String Terminator) preprocessor
+	symbols for these ECMA-48 (ISO 6429) character sequences.
+	(tty_printer::simple_add_char): Add stripped-down alternative to
+	`add_char()` member function for cases where we want to use many
+	defaults because we're writing a terminal escape sequence, not
+	rendering a glyph.  (A function like `add_char()` that takes 8
+	arguments of varying types is a code smell--phew!)
+	(tty_printer::special): Call `special_link()` member function if
+	the device control command is `link`.
+	(tty_printer::special_link): Add new member function to generate
+	OSC 8 hyperlinks.
+
+	* src/devices/grotty/grotty.1.man: Document it.  Observe in
+	multiple places that disablement of SGR escape sequences
+	disables OSC 8 too.

+
+	[troff]: Convert special character glyphs corresponding to
+	Unicode Basic Latin ("ASCII") code points to those code points
+	when they occur in device escapes.  (They should be correct for
+	IBM code page 1047 as well, but this is untested.)  This is
+	necessary for encoding URLs in device control commands.  Special
+	character identifiers are presumed to be the defaults documented
+	in groff_char(7); this is a design gap that we should consider
+	addressing.  (We don't have a way to ask "is this the special
+	character corresponding to Unicode basic Latin code point X?")
+
+	* src/roff/troff/input.cpp (encode_char): Do it.

+
+	* tmac/an.tmac (an-bp): Move responsibility for line-drawing
+	after each document from here...
+	(an-end): ...to here.  Refactor; drop
+	`an-do-draw-line-after-document` register in favor of testing
+	`\n[.F]` for nullity; if it is not null, then another document
+	is due to be processed (in fact, `.F` already contains its file
+	name), and we need to draw a separating line.  If it is null, we
+	have reached the end of input and none is necessary.
+
+	* tmac/mdoc/doc-ditroff.tmac (doc-setup-page-layout):
+	* tmac/mdoc/doc-nroff.tmac (doc-setup-page-layout): Save

+

+	to this copy in `last_filename` instead of aliasing argument.
+	(troff_output::~troff_output): `free()` the memory allocated by
+	`strdup()` in destructor.
+
+	Fixes <https://savannah.gnu.org/bugs/?61206>.  Pointer
+	assignment instead of a string copy was being performed, which
+	means that after its initial assignment, `last_filename` always
+	shared its value ultimately with the `current_filename` pointer
+	{a libgroff symbol}, so `strcmp()` was always being performed on
+	identical pointers.  Problem appears to date back 30+ years, to
+	the dawn of our repo history.

+
+	[libgroff]: Perform more font description file validation.  Our
+	documentation said that the `name` directive was mandatory but
+	we didn't actually enforce this.  Also be more specific in our
+	complaints of ill-formedness.
+
+	* src/libs/libgroff/font.cpp (font::load): Add local Boolean
+	variable `saw_name_directive`.  Rename `had_charset` to
+	`saw_charset_directive` for symmetry.  Emit distinct diagnostics
+	for `spacewidth` and `slant` directives having a missing,
+	non-numeric, or out-of-range argument.  Emit diagnostic if the

+
+2021-09-23  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[libgroff]: Slightly refactor.
+
+	* src/libs/libgroff/font.cpp (struct text_file): Rename member
+	variable `size` to `linebufsize` for clarity (it's certainly not
+	the size of the text file).
+	(text_file::text_file): Initialize `linebufsize` in constructor.
+	(text_file::next_line): Allocate new `buf` using `linebufsize`
+	instead of magic number (which was also stored to `size`, making
+	it only semi-magic, I guess).  Rename local variable `i` to
+	`length` since it is in fact the length (in `char`s) of the

+	font::get_left_italic_correction,
+	font::get_subscript_correction, font::get_character_type,
+	font::get_code, font::get_special_device_encoding): These member

+	with an output device that uses the `unicode` directive in its
+	`DESC` file.  The compiler doesn't know this, so annotate the
+	`abort()` calls that conclude them.  Add an `assert()` before
+	each one to more usefully describe the violated invariant in the
+	event this unreachable code is somehow reached.
+	(font::get_width): Annotate special meaning of zero zoom factor.

+	Drop test of font description file name being `DESC`; this code
+	was not being reached.  Stop throwing errors from this function
+	on failure to open the file; the caller will handle this when it
+	sees our false return value.  Rename local variable `command` to
+	`directive` for alignment with our documentation.  Replace "I
+	dont think this should happen" test and comment with `assert()`.
+	(struct table): Rename member from `command` to
+	`numeric_directive` to indicate its specificity, tracking only a
+	subset of valid `DESC` file directives.
+
+	* src/libs/libgroff/font.cpp (font::load, font::load_desc):

+	clarify logic.
+
+	* src/roff/troff/node.cpp (mount_font_no_translate): Simplify
+	call of `font::load_font`.  The `not_found` in-out parameter
+	which was so agonizingly passed up through layers of library

+	open, which might reveal a user's logic error or typo.
+	* src/roff/groff/groff.cpp (main): Replace "invalid device" text
+	of fatal diagnostic similarly.  I think it is more helpful to
+	indicate the operation that failed rather than saying the device
+	was invalid, particularly since there are other ways for a
+	device description to be invalid even if a DESC file is found
+	and loaded.

+	style mount warning will never actually trip.
+
+2021-09-15  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[troff]: Lift font mounting diagnostic messages to be closer to
+	their user-controlled contexts to provide more information.  In
+	many cases no diagnostic was being thrown at all when an
+	unavailable font was requested by name, which is the method most
+	users prefer, and which meant that failures resulting from typos
+	in font names for many requests (`uf`, `fschar`, `rfschar`,
+	`special`, `fspecial`, `fzoom`, `bd`, `tkf`, `cs`) were going
+	unreported.  Further, promote these font warnings to errors
+	because the request will utterly fail to do what was requested
+	with no reasonable fallback.  Possibly, they were formerly
+	warnings because at the low level they were being emitted, they
+	could also have originated from unavailable fonts encountered in
+	device description files, and while that's bad news, it results
+	in no formatting problems if it doesn't affect fonts that an
+	input document actually uses.
+
+	* src/roff/troff/node.cpp (struct font_lookup_info): New struct
+	keeps the font name or position requested, and the position of
+	successful font lookup.
+	(font_lookup_info::font_lookup_info): Add constructor.
+	(font_lookup_error): New function builds error message using a
+	`font_lookup_info` struct and a message argument.
+	(get_fontno): Rename to...
+	(has_font): ...this.  Add argument to take a pointer to a
+	`font_lookup_info` struct.  Return a `bool` indicating whether
+	the lookup succeeded.  Place former `int` return value into the
+	struct instead.  Populate the other struct members with the
+	requested font name or position, as appropriate.
+	(mount_font_no_translate): Stop throwing warning diagnostic here
+	if a font cannot be loaded.  Instead, throw them...
+	(font_position): ...here, and...
+	(underline_font, define_font_special_character,
+	remove_font_special_character, read_special_fonts,
+	font_special_request, font_zoom_request, bold_font, track_kern,
+	constant_space): ...here, using `font_lookup_info` structs and
+	`has_font()`.
+	(remove_font_special_character): Stop returning early if font
+	lookup fails; it's gratuitously inconsistent with other similar
+	functions (save one, which has a reason to be different).
+	(define_font_special_character): Return early if font lookup
+	fails and say why in a comment (we can't `skip_line()`).

+
+	* Makefile.am: Add `.DELETE_ON_ERROR` special target; both GNU
+	and FreeBSD make(1)s support it so maybe it will be portable

+	process generating it experiences an assertion failure.

+
+	Since June 1991 if not earlier, groff (technically, the refer,
+	lookbib, and lkbib programs) has trusted the header contents of
+	binary bibliographic index files (canonically generated with
+	indxbib(1)) regarding the sizes of the data structures that
+	follow in the file, a notorious class of security problem.  In
+	July 2013, the Mayhem Team at Carnegie Mellon University
+	reported to the Debian Bug Tracking System a problem with
+	groff's refer(1) implementation dumping core when reading an
+	index file prepared by a fuzzer.
+
+	* src/libs/libbib/index.cpp (index_search_item::check_header):
+	Add new member function to validate the header of an indexed
+	bibliography file, returning a string describing in detail the
+	first validity problem encountered.
+	(index_search_item::load): Perform the foregoing check before
+	using any of the size values taken from the header; they are
+	relied upon for pointer arithmetic.  If in verification mode
+	{using the undocumented `-V` flag to refer(1), lkbib(1), or
+	lookbib(1)}, report the details of the problem encountered.
+	Regardless of that mode, if there is a validity problem, report
+	corruption of the index file and abandon it, forcing fallback to
+	the text version of the corresponding bibliography file.
+
+	Fixes <https://bugs.debian.org/716109>.

+
+	* src/libs/libbib/index.cpp
+	(index_search_item::get_invalidity_reason): Don't complain about
+	a last list element being nonnegative if the list size was zero
+	in the first place, as can happen with an empty index.  More
+	seriously from a language standpoint, avoid reading through a
+	negative array index (this can escape a compiler's attention
+	because we're reading from the midst of a heap-allocated or
+	`mmap()`ed region, but it's still a code smell).
+
+	Fixes <https://savannah.gnu.org/bugs/?61144>.

+	* src/libs/libbib/index.cpp (index_search_item::load)
+	(index_search_item::get_invalidity_reason)
+	(index_search_item::add_out_of_date_file): Clarify diagnostic
+	messages.  Make it more obvious when we're complaining of a
+	problem in an indexed bibliographic database file (rather than a
+	plain text one).  Dial down the amount of Unix jargon a little.

+
+	[libbib]: Partially boolify.
+
+	* src/include/search.h:

+	* src/preproc/refer/refer.cpp:
+	* src/utils/lkbib/lkbib.cpp:
+	* src/utils/lookbib/lookbib.cpp: Demote `verify_flag` from an
+	`int` to a `bool`, rename it to `do_verify`, use Boolean
+	instead of integer literals with it, and update call sites.
+
+	* src/libs/libbib/index.cpp: Rename `do_verify()` member
+	function to `get_invalidity_reason()` (it returns a string).
+	Demote `load()` from `int` to `bool`; do the same for `verify()`
+	and rename it to `is_valid()` as well.  Use Boolean instead of
+	integer literals with them.
+	(index_search_item::is_valid, make_index_search_item): Update
+	call sites of renamed member functions.
+
+2021-09-12  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/libs/libbib/map.c (mapread): Compare return value of
+	`mmap()` to `MAP_FAILED` instead of `(char *)-1`.  `MAP_FAILED`
+	is documented in POSIX Issue 5 a.k.a. SUSv2
+	<https://pubs.opengroup.org/onlinepubs/007908799/xsh/mmap.html>
+	{1997} and should be portable enough by now.
+
+2021-09-11  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[troff]: Clamp negative tab stop positions to zero instead of
+	throwing an assertion failure.
+
+	* src/roff/troff/env.cpp (tab_stops::distance_to_next_tab):
+	Replace `assert` with clamping logic, ensuring that `lastpos`
+	can never be negative.  While negative tab stop positions don't
+	make much sense (they result in zero horizontal motion), user
+	input like `.ta T -5` should never provoke an assertion failure.
+
+	(set_tabs): Throw range warning in additional scenario, viz., if
+	a repeating tab offset is negative.
+
+	Fixes <https://bugs.debian.org/990406>.  Thanks to наб for the
+	report.

+	  - `first` -> `is_first_stop`
+	  - `repeated` -> `is_repeating_stop`
+	Use Boolean instead of integer literals in assignments to them.

+	deprecated.
+
+2021-09-07  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[troff]: Make `ab` request quiet if given no arguments.  The
+	`tm`, `tm1`, and `tmc` requests provide ample flexibility for
+	constructing diagnostic messages prior to an error exit, and
+	it's convenient to make `ab` itself quiet instead of saying
+	"User Abort." as Unix Version 7 troff did.  Further, there is no
+	standardization across troffs regarding what `ab` should emit if
+	arguments are absent.
+
+	* src/roff/troff/input.cpp (abort_request): Do it.
+
+	* src/roff/groff/tests/ab_works.sh:
+	* src/roff/groff/groff.am (groff_TESTS): Test it.

+	[troff]: Don't adjust nonadjustable lines.  This means that the
+	direction from which an output line in adjustment mode "b" (or
+	its "n" synonym) is filled with supplemental space is not
+	changed if that output line does not require adjustment.  This
+	will result in whitespace changes to documents using that
+	adjustment mode, and these changes will be plainly visible on
+	low-resolution output devices like terminals.
+
+	To illustrate, in the following "A" means an output line
+	requiring adjustment; "F" a line that is "full" and does not;
+	and "L" and "R" indicate distribution of adjustment spaces from
+	the left and right, respectively.

+
+	[libgroff]: Drop `ad_delete` preprocessor wrapper for the

+

+
+2021-08-28  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* m4/groff.m4 (GROFF_ARRAY_DELETE): Update `AC_MSG_CHECKING`

+
+2021-08-27  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[libgroff]: Drop support for `ARRAY_DELETE_NEEDS_SIZE`.
+
+	* src/include/lib.h [ARRAY_DELETE_NEEDS_SIZE]: Drop preprocessor
+	conditional branch.  This abandons support for certain pre-ISO
+	C++98 compilers.  (According to a now-removed comment, unsized
+	array deletion was documented in "ARM", meaning _The C++
+	Annotated Reference Manual_, published in 1989.)
+
+	* Makefile.am: Undocument preprocessor symbol.
+
+2021-08-27  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[libgroff]: Drop redefinition of `INT_MIN`.
+
+	* src/include/lib.h: Drop redefinition of `INT_MIN`.  It was
+	motivated by a bug in the AT&T C++ compiler (cfront), version
+	2.0, released in June 1989.  Implementations have had 30 years
+	to get this right; assume that they have.
+
+	* PROBLEMS: Drop corresponding item.
+
+2021-08-27  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[libgroff]: Drop long-dead `COOKIE_BUG` logic.
+
+	* src/libs/libgroff/new.cpp (operator new, operator delete):
+	Drop preprocessor conditional branches on the `COOKIE_BUG`
+	symbol.  This was de-documented, and an autoconf check for its
+	necessity removed, way back in groff 1.10 (November 1995).  It
+	was relevant only to GCC from versions 2.0 to 2.2.2 (all 1992).
+
+2021-08-24  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[libgroff]: Refactor `font::scan_papersize()`.
+
+	* src/libs/libgroff/font.cpp (font::scan_papersize): Ensure
+	successful return value of `fgets()` before attempting to parse
+	string for paper format.  Convert `test_file` to Boolean and
+	rename to `attempt_file_open`.  Quiets GCC `-Wunused-result`
+	warning.
+
+2021-08-23  G. Branden Robinson <g.branden.robinson@gmail.com>

+2021-08-23  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an.tmac (IP): Make code more accessible by using a
+	Boolean operator rather than an arithmetic one (assembly
+	language programmers are comfortable with the interchangeability
+	of subtraction and comparison, but not everyone is).
+
+2021-08-23  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	groff(7): Document more escapes.
+

+	Revise descriptions of `\O0` and `\O1` escape sequences.
+	Document `\O2`, `\O3`, `\O4`, and `\O5` escape sequences.
+
+2021-08-23  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	groff(7): Fix bug in `\?` escape rendering.
+
+	* man/groff.7.man (ESC?): Fix bug in page-private macro: the
+	question mark that ends this uniquely-syntaxed escape sequence
+	was not shown with the mandatory escape character before it.
+	Problem dates back at least to commit 41b0e794, 19 February
+	2007, but possiby to f790bc7a9, 6 January 2002.

+

+	Add global `lineno`.
+	(DBRead): Increment `lineno` after reading newlines from input.
+	Call `error_with_file_and_line()` instead of `error()`.  If

+
+2021-08-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/grn/hdb.cpp (DBRead): Check return value of
+	`sscanf()` and call `fatal()` if no conversions succeeded.  The
+	blithe discard of a useful return value is bad enough, but this
+	one took place inside a do-while such that it could loop
+	forever trying fruitlessly to parse two doubles out of strings
+	that didn't contain them (the loop never checked the EOF status
+	of the file stream from which it was reading, and relied on
+	`fgets()` to keep advancing the stream pointer).  Discovered
+	while root-causing Savannah #61043.

+	safe in a comment.
+
+	* src/preproc/preconv/preconv.cpp (detect_file_encoding): Use
+	`l` modifier to `%u` `fprintf()` conversion instead of `z`, and
+	cast return values of `size_t` to unsigned long; "ISO C++98
+	does not support the ‘z’ gnu_printf length modifier" (it doesn't
+	support `ll` either).  N.B. this is debugging output only.
+
+	* src/roff/groff/groff.cpp (synopsis):
+	* src/roff/troff/input.cpp (usage): Repeat variadic argument for

+	{see groff_man(7)} should have to worry about.
+
+	* tmac/an.tmac (BT): Drop test of `ps4html` register and early
+	return.
+	(an-header, an-footer): Return immediately if
+	`an-suppress-header-and-footer` is true.  Remove conditional on

+	names, accept any non-whitespace character (Perl: \S) instead of

+	* src/utils/grog/grog.pl: Refactor macro package inference.
+	  - Stop manually populating `Groff` hash.  (It's itching for a
+	    rename.)
+	  - Stop calling now-dead subroutine `infer_macro_packages`.
+	(do_line): Always store the names of all macros called to the
+	`Groff` hash, incrementing it.  Now it's a proper scoreboard.
+	Populate `inferred_main_package` from here upon encountering
+	characteristic (i.e., uniquely named) macros of each package.
+	Bug fix: drop "SP" from list of characteristic mom(7) macros;
+	it's shared with mm(7).
+	(infer_man_or_ms_package): Update comment.  Return 0 (false) if
+	document appears to be "raw", using no full-service macro
+	package.
+	(infer_macro_packages): Delete; do_line() does this work.

+
+	* src/utils/grog/grog.pl: Refactor preprocessor inference.
+	  - Add new list, `inferred_preprocessor`.
+	  - Drop preprocessor-related keys from `Groff` hash.
+	  - Drop scalar `inside_tbl_table`.
+	(do_line): Set up hash `preprocessor_for_macro`.  Detect
+	preprocessor macros the way the preprocessors do, explained in a
+	comment.  Respect AT&T compatibility mode when doing so.  Build
+	list of inferred preprocessors.  This replaces the extensive and
+	gaseous series of `if` statements that manipulated the `Groff`
+	hash.
+	(infer_preprocessors): Completely replace.  Set up a hash
+	`option_for_preprocessor` mapping preprocessor names to groff
+	options (where applicable).  Append to `command` and
+	`preprocessor` lists as appropriate.  Sort the preprocessor
+	options so they don't move around in the argument list depending
+	on the order of their macros' appearance in the input.
+
+	* src/utils/grog/tests/smoke-test.sh: Update test cases to

+	when saving a new image file name.  Use saved length in later
+	expressions.
+	(min): Drop unused inline function.

+	[troff]: Refactor some internal functions.
+
+	* src/roff/troff/node.cpp: Rename two functions that have only
+	one caller.
+	  - get_reg_int -> get_register
+	  - get_reg_str -> get_string
+	We now have:
+	(get_register, get_string): Use `assert()` aggressively because
+	these are deeply internal and validation is imperative.  Get rid
+	of diagnostic messages (one of which perpetuated the dubious
+	"number register" nomenclature) accordingly.
+	(fetch_register): Also rename `prev_value`, misleadingly
+	specific and seemingly copy-and-pasted out of a context where an
+	auto-increment or -decrement might have been applied.  It's just
+	the `value`.
+	(suppress_node::tprint): Update call site.
+
+2021-07-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[troff]: Refactor `get_value` member functions.  Given their
+	names and popular "getter/setter" paradigms from many OO
+	languages, the return type is misleading.  Change it from `int`
+	to `bool` since it returns only a success/failure status and
+	modifies an argument (passed by reference) to deliver the
+	requested data.

+
+	[grohtml]: Fix Savannah #60981.  Refactor device description
+	file handling and make it more robust.  Make pre-grohtml's
+	-F option work as documented and honor device description file
+	semantics documented in groff_font(5).
+
+	* src/preproc/html/pre-html.cpp: Store partial filespecs of HTML
+	and PostScript device files in constant strings.
+	(get_resolution): Initialize `res` to zero.  Only `free()` the
+	pointer `pathp` if `open_file()` succeeded (populating it).
+	Stop checking for valid `sscanf()` conversions of an integer to
+	store in `res`, and don't return early.  Instead process the
+	whole DESC file; per our Texinfo manual and groff_font(5),
+	"Later entries in the file ... override previous values."
+	(get_image_generator): Add new function, paralleling
+	`get_resolution()`, replacing open-coded logic in `main()`.
+	Only the body of the `while` loop significantly differs.
+	Instead of using `sscanf`, process the input character by
+	character matching the keyword and {1,} spaces or tabs
+	after it.  Whatever follows in `linebuf` must be the program
+	name.
+	(imageList::createPage): Add `assert()` to cause failure if an
+	empty image generator program gets this far, because it creates
+	repeated messes if it does.  (Something isn't checking exit
+	statuses.)
+	(main): Condense `image_gen` collection to a function call, a
+	null pointer check, and a fatal diagnostic.  Add a sanity check
+	and a fatal diagnostic if the PostScript resolution is garbage.
+	{It's initialized to -1 and `get_resolution()` will return 0 if
+	it doesn't find one.}

+
+	* src/roff/nroff/nroff.sh: Fix straggling use of `$1`, which

+	* src/roff/troff/node.cpp (suppress_node::tprint): Recast
+	diagnostic to prevent misinterpretation of image "description"
+	as being HTML IMG tag alt text or something like that.
+	Unfortunately, the new language speaks in terms of internal
+	implementation details ("grohtml-info"), but at least that way
+	it's easier for a user to decide if they care about it.

+
+	[troff]: Avoid using sprintf() with user-controlled format
+	string.
+
+	* src/preproc/html/pre-html.cpp (makeFileName): Add comment
+	noting need for implementation synchrony between this function,
+	which generates \O5 escape sequences, and troff's
+	suppress_node::tprint member function, which interprets them.
+	* src/roff/troff/node.cpp: Rename 2 static globals for clarity.
+	  - `last_image_filename` -> `image_filename`
+	  - `last_image_id` -> `subimage_counter`
+	(suppress_node::tprint): Set up the buffer for image file name
+	to be written using a constant rather than an embedded literal.
+	Unconditionally initialize the buffer with a string terminator,
+	so there is no chance of a read from uninitialized storage.
+	Drop unused code involving `tem`.  Drop stale comments.  Clarify
+	comment: an `image_filename` doesn't _always_ contain a format
+	string, only sometimes.  Replace use of `sprintf` with manual
+	construction of a new image filename string.  There are two
+	cases, one where a format string {presently "%d"} is present,
+	and one where it is not.  If it is present, locate it
+	{`percent`}.  This means a limited/bounded image ("subimage") is
+	being processed; increment the subimage counter.  Write a new
+	image file name preserving the parts before and after "%d" (the
+	"prefix" and "suffix", and replacing only the middle, using
+	`sprintf` with the subimage counter and the (string literal)
+	format.  Be mindful of string bounds and memory allocation,
+	issuing diagnostics or aborting as necessary.  If the image file
+	name does _not_ contain a format string, but needs only to be
+	copied, do that (`strcpy`), again instead of using `sprintf`.

+
+	* src/utils/hpftodit/hpftodit.cpp (show_symset): Prevent

+	absorb the argument into the groff option list and clear the
+	flag.  Modernize script in a couple of other ways.
+	  - Exit with status 2 upon usage errors so that this condition

+	[troff]: Refactor environment initialization, switching, and

+
+	* src/roff/troff/env.cpp: Rename struct `env_list` to
+	`env_list_node` since it describes a node of a singly-linked
+	list.  Remove constant `NENVIRONMENTS` and array `env_table`.
+	Add static symbol `default_environment_name` to replace string
+	literal.
+	(init_environments): Stop initializing `curenv` through
+	`env_table`.  Use `default_environment_name` for that
+	initialization and add the default environment to
+	`env_dictionary`.
+	(environment_switch): Simplify.  Shorten "dummy environment"
+	diagnostic message.  Stop creating an integer-named
+	environment inside the `env_table` array, only falling through
+	to use the `env_dictionary` if the named environment is not a
+	valid integer or if the array is full.  Instead use
+	`env_dictionary` always.  Drop no longer needed `pop`
+	quasi-Boolean integer with extra state to suppress environment
+	stack underflow errors.  Instead report the error if underflow
+	occurs, regardless of any other circumstance.
+	(environment_copy): Simplify.  Stop searching the `env_table`
+	array for an environment to copy from, only falling through to
+	use the `env_dictionary` if the named environment is not a valid
+	integer or if the array is full.  Instead search
+	`env_dictionary` always.  Emit "no environment specified to copy
+	from" diagnostic only if the `evc` request is given no argument.
+	If the source environment to copy from is given but not found,
+	emit a new diagnostic naming the nonexistent environment.  Fix
+	bug: stop returning early if no copying could be done; instead
+	fall through to the end of the function, which calls
+	`skip_line()` and prevents anything on the remainder of the
+	{invalid} control line from being interpreted.  Problem dates

+	broad swaths of the file including portions outside of any macro
+	definition where comments were used.  But comments are expressed
+	using the escape character!  So we got warnings about an
+	undefined '\"' macro, and that was just the beginning of a
+	wrecking ball of trouble that smashed through the
+	implementation.  Some--but not all--string definitions (and
+	appendments) needed to be bracketed with `eo` and `ec` as well,
+	to delay interpolation of embedded string names that are not
+	defined until macros interpolate them later.  I did what
+	appeared necessary to pass our tests and keep -Tutf8 and -Tps
+	renderings of tmac/groff_mdoc.7 from changing from their
+	strip-influenced output.  Subtle bugs might linger, but some
+	won't be the fault of the unstripping process.  (For instance,
+	try provoking a usage message on the `Hf` macro.)

+
+	* tmac/hyphen.it: Add hyphenation patterns from TeX hyph-utf8
+	project.
+	* tmac/it.tmac:
+	  - Revise copyright date to just this year (it had been copied
+	    from fr.tmac).
+	  - Use grave accents instead of acute ones to indicate stress
+	    on word-final vowels.  Per the University of Wikipedia and a
+	    sampling of apparently well-typeset Italian language
+	    documents online, this appears to be correct.  Yell at me if
+	    I'm wrong.
+	  - Source latin1.tmac instead of latin9.tmac; Italian doesn't
+	    require any letter code points from Latin-9, unlike the
+	    French file upon which this one was based, and Latin-1 is
+	    less of a pain to work with.
+	  - Set the hyphenation mode to 1 instead of 4 for congruence
+	    with the requirements of the hyphenation patterns.
+	  - Set up hyphenation codes.  This (and sourcing latin1.tmac)
+	    might not be necessary as the hyphenation pattern file, of a
+	    more recent vintage than the others we're using, is pure
+	    ASCII.  However I don't understand these issues perfectly so
+	    I am making the conservative choice.  Again per the
+	    University of Wikipedia, Italian requires only acute and
+	    grave accents, in contrast to the rich French diacritical
+	    bouillabaisse.
+	  - Set the hyphenation language and load the pattern file.
+	  - Add comments in parallel with other localization files and
+	    to supply text editors with hints.

+
+	[grog]: Refactor input parsing.
+
+	* src/utils/grog/grog.pl:
+	  - Add scalar `use_compatibility_mode` (see below).
+	  - Add list `request` to store the names of all requests
+	    recognized by groff so that they aren't confused with macro
+	    names.
+	  - Add scalars `have_seen_first_macro_call` (replaces
+	    `before_first_command`, but at global scope),
+	    `is_continued_line` and `logical_line`.  The latter two
+	    enable us to handle *roff input line continuation correctly.
+	  (process_arguments): Set `use_compatibility_mode` if `-C`
+	  option specified.
+	  (process_input): Refactor to greatly simplify, to not attempt
+	  to read the first line of an input file as a special case, and
+	  to avoid sending `do_line` an undefined argument (when EOF is
+	  reached).
+	  (do_first_line): Delete.
+	  (do_line): Rewrite the early stages of input parsing.
+	  - Concatenate continued input lines, setting
+	    `is_continued_line` and returning early as each one is seen,
+	    storing the accumulating input in `logical_line`.
+	  - Check the input line for the form of comment deposited by
+	    Perl's Pod::Man, which uses a highly accented dialect of
+	    man(7); if it's present, inflate `man_score` to compensate
+	    for the page-private `IX` macro it defines but which
+	    duplicates the name and function of a 4.2BSD-era ms(7)
+	    extension that would otherwise deceive our scoring
+	    mechanism, because Pod::Man produces `IX` calls to
+	    metastatic excess.  (An alternative to this kludge is
+	    documented in comments: if a "standard" macro is redefined,
+	    we could delete it from the relevant lists and hashes.)
+	  - Strip *roff comments from input.
+	  - Normalize control lines; convert the no-break control
+	    character to the regular one and remove unnecessary
+	    white space.
+	  - Remove brace escapes.
+	  - Recognize two-character macro calls when not followed by
+	    white space in compatibility mode.
+	  - Drop logic that erroneously attempted to infer soelim(1) use
+	    from macro calls and request invocations.  The grog(1) and
+	    soelim(1) man pages now both explain why such an effort was
+	    misguided.
+	  - Recognize macro definitions created by .am and .am1 requests
+	    {not just .de and .de1}.
+	  - Ignore all other *roff requests.
+	  - What remains must be a ("standard") macro call, so set
+	    `have_seen_first_macro_call`.
+
+	* src/utils/grog/grog.1.man (Limitations): Document a further
+	restriction: don't change the escape character, either.
+
+	* src/utils/grog/tests/smoke-test.sh: Comment out pic-detection
+	test on soelim(1).  The pic macro calls are guarded by roff
+	control structures and only worked previously by accident
+	because grog did not recognize *roff input line continuation,
+	now it does and the illusion is dispelled.  (A reliable way to
+	fool grog before and after my refactoring is now documented in
+	its man page.)

+	  groff command's argument list (`-m` handling is unchanged).
+	  Match long option names exactly, not sloppily.  Stop
+	  recognizing `--warnings` option.  Emit error diagnostic if
+	  unrecognized long option encountered.
+	  (infer_device): Delete subroutine and its top-level call site.
+	  (help): Undocument `--warnings`.
+
+	* src/utils/grog/grog.1.man:
+	  (Synopsis): Use font style macros instead of .OP.  Undocument
+	  `--warnings`.
+	  (Options): Note that the groff arguments produced by the grog
+	  `--ligatures` option are supported only by the `pdf` device.
+	  Undocument `--warnings`.  Undocument groff-incompatible
+	  restriction on whitespace before option arguments; grog is
+	  compatible now.  Simplify discussion in light of simplified
+	  grog logic.
+	  (Details): Undocument scenario where grog infers multiple
+	  main/major/full-service macro packages; this no longer
+	  happens.
+	  (Examples): Update to no longer illustrate inclusion of `-T
+	  ps` option; this no longer happens by default.
+
+	* NEWS: Document removal of grog's `--warnings` option.
+
+	Fixes <https://savannah.gnu.org/bugs/?57873>; groff options are
+	no longer "mangled".
+
+2021-06-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Add regression test for Savannah #57873.
+
+	* src/utils/grog/tests/preserve-groff-options.sh: Test it.
+	* src/utils/grog/grog.am (grog_TESTS): Run test.
+
+2021-06-28  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[grog]: Refactor device (`-T` option) handling.
+
+	* src/utils/grog/grog.pl: Redeclare `device` as a scalar instead
+	of a list.
+	(process_arguments): Generalize handling of `-T` and `-m`
+	options to permit optional whitespace.  Rename scalar `was_T` to
+	`delayed_option`.
+	(infer_device): Stop unconditionally adding a `-T ps` argument
+	to the generated groff command.  Remove logic that validates any
+	given `-T` option argument; instead, let groff fail if a bad one
+	is supplied (its own diagnostics in this scenario were improved
+	in commit 5a721a30, 27 May).  This makes grog agnostic about any
+	differently configured default device in groff itself, and about
+	the GROFF_TYPESETTER environment variable.
+
+	Fixes <https://savannah.gnu.org/bugs/?55301> by getting out of
+	the way.
+
+	* src/utils/grog/tests/PF-does-not-start-pic-region.sh:
+	* src/utils/grog/tests/smoke-test.sh: Update expected output.
+
+2021-06-28  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/utils/grog/grog.am (grog): Drop sed replacement of unused
+	configuration variables @g@, @BINDIR@, @libdir@, and @EGREP@.
+	* src/utils/grog/grog.pl (process_arguments, construct_command):
+	Tweak warning diagnostics to use a style where an empty argument
+	will be easy to spot.
+	(do_first_line): Stop emitting pseudo-diagnostic (to standard
+	output!) if we see a "groff options line" [it's not] of
+	incorrect form.  The preprocessor encoding hint convention of
+	concern here is particular to man pages, disregarded by at least
+	one major implementation thereof (man-db man), and not used by
+	other types of roff documents; at this point, we don't yet know
+	if the document we're processing is a man page.
+	(construct_command): Correct comment and related logic error.
+	Clear the inferred main macro package if _any_ `-m` argument
+	matching any main macro package is given.  Warn only if what is
+	specified doesn't match the inference.
+
+2021-06-28  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[grog]: Heavily refactor.
+
+	* src/utils/grog/grog.pl:
+	  - Drop import of unused module `Data::Dumper`.
+	  - Drop unused scalars `Sp` and `correct_tmac`.
+	  - Simplify determination of version number.  Drop hash `at_at`
+	    which only stored one key, `GROFF_VERSION`.  Initialize
+	    scalar `groff_version` to "DEVELOPMENT".  Rename scalar
+	    `before_make` to `in_source_tree` and initialize to zero.
+	    Update `groff_version` with Automake-determined version
+	    variable if it is defined (i.e., grog is not running outside
+	    of, or in an unbuilt, groff source or binary distribution).
+	  - Drop unused `Mparams` list.  Replace it with new list
+	    `requested_package`, which stores the arguments to any grog
+	    `-m` options specified by the user.
+	  - Rename many objects so that I, and others, can better
+	    comprehend their purpose, and for consistent letter casing.
+	    . @Command -> @command
+	    . @devices -> @device
+	    . $Prog -> $program_name
+	    . %macros -> %user_macro
+	    . $have_any_valid_args -> $have_any_valid_arguments
+	    . &handle_args -> &process_arguments
+	    . &handle_whole_files -> &process_input
+	    . @preprograms -> @preprocessor
+	    . &make_groff_device -> &infer_device
+	    . &make_groff_preproc -> &infer_preprocessors
+	    . &make_groff_tmac_others -> &infer_macro_packages
+	    . &make_groff_tmac_man_ms -> &infer_man_or_ms_package
+	    . &make_groff_line_rest -> &construct_command
+	  - Drop many unused keys in `Groff` hash.
+	  - Add new lists, `macro_ms`, `macro_man`, and
+	    `macro_man_or_ms` to support new scoring technique to
+	    disambiguate input documents between these two packages.
+	  - Append the foregoing 3 lists to new list `standard_macro`,
+	    and add these as keys to the `Groff` hash.
+	  - Add new list `main_package` to keep track of full-service
+	    package names.
+	  - Add new scalars `man_score`, `ms_score`, and
+	    `inside_tbl_table` to aid disambiguation of .TH macro calls
+	    and the many macro names shared between man(7) and ms(7).
+	  (process_arguments): Strip '-m' off of argument before storing
+	  the remainder in `@requested_package`.
+	  (do_line): Detect .TH macro call even if white space occurs
+	  between the control character and the macro name.
+	  (do_line): Inflate `$man_score` by 100 if .TH is the first
+	  macro call seen in a document.
+	  (do_line): Fix bug; clear `$before_first_command` in correct
+	  scope--after any macro call, not just if we saw a .TH as the
+	  first macro call.
+	  (do_line): Set `$inside_tbl_table` when we see a .TS call.
+	  (do_line): Clear `$inside_tbl_table` when we see a .TE call.
+	  Also increment `$Groff{'tbl')' again, increasing the "score"
+	  of tbl(1) usage evidence.
+	  (do_line): Drop a lot of code that manually increments %Groff
+	  keys corresponding to man and ms macros.  This is now done
+	  differently and elsewhere.
+	  (do_line): Drop "P" from list of characteristic mm(7) macros.
+	  (do_line): Simplify matching of mom(7) macros (match $command,
+	  not $line).  Extend list of characteristic mom(7) macros.
+	  (do_line): Increment $Groff{$key} if $key is in
+	  @standard_macro.
+	  (infer_man_or_ms_package): Rewrite.  Compute a score for each
+	  package by counting occurrences of their characteristic
+	  macros.  If both have a score of zero, assume that the input
+	  is a raw roff document.  If the scores are equal
+	  {doc/webpage.ms, startlingly, comes within 1 point of a tied
+	  score}, infer ms(7) if 'TH' was never called, and if it was,
+	  issue a diagnostic advising user to supply a disambiguating
+	  `-m` option.  Otherwise, the scores are unequal: infer the
+	  package of the winner.  Set scalar `inferred_main_package`
+	  instead of pushing `-m` options onto `@m`.
+	  (infer_macro_packages): Set scalar `inferred_main_package`
+	  instead of pushing `-m` options onto `@m`.  Explicitly return
+	  0 if we fall off the end of the function.
+	  (construct_command): Rewrite handling of -m options.  Add new
+	  list `msupp` to store supplementary (non-main) macro package
+	  arguments.  If a full-service package was explicitly
+	  requested, it had better not clash with what we inferred.  If
+	  it does, explicitly unset `inferred_main_package` so that the
+	  -m arguments are placed in the same order that the user gave
+	  them; caveat dictator.  If `--run` option was given, just
+	  print the command; don't preface it with __FILE__ and __LINE__
+	  noise.
+	  - Remove comments documenting shared variables used by
+	    subroutines.  These are far from useless but too tedious to
+	    keep up to date while the code is in flux.
+	  - Note several places for further code review or refactoring
+	    with "XXX" comments.
+	  - Add Vim modeline.
+
+	grog now passes all its tests and correctly infers arguments for
+	all in-tree groff documents (except for a known, and already
+	documented in grog(1), false positive detection of soelim in
+	soelim(1)).  This refactor also obviates or resolves several
+	outstanding Savannah tickets.
+
+	Fixes <https://savannah.gnu.org/bugs/?44707> by obviating it;
+	grog no longer cares about file name extensions on man pages (or
+	any other input).
+
+	Fixes <https://savannah.gnu.org/bugs/?55302>; same.  The quality
+	of diagnostic messages has been improved as well.
+
+	Fixes <https://savannah.gnu.org/bugs/?59753>; same.
+
+	Fixes <https://savannah.gnu.org/bugs/?59664>.  The attached
+	patch was a less aggressive refactor of &do_line and %Groff.
+	Its author made the following claim for it: "With this patch,
+	all 'man', 'me', 'mom, and 'ms' files in the repository are
+	correctly identified.  The only example of a 'mm'-file is
+	"letter.mm", which is not recognized correctly."  As noted
+	above, the present refactor achieves correct recognition of all
+	of the files, including letter.mm.
+
+2021-06-28  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/utils/grog/tests/smoke-test.sh: Perform whole-line
+	matches.  Apply DRY principle to expected output.  In
+	anticipation of pending changes to grog.pl, uncomment and add
+	tests for several in-tree documents.

+
+	[grog]: Refactor.  Discard filename extension-based inference.
+
+	* src/utils/grog/grog.pl (do_line): Stop saving the control
+	character in the matched scalar `command` (the request or macro
+	name).  We don't need it, and it simplifies much later matching.
+	(handle_file_ext): Delete.
+	(top level): Drop call site.
+
+	* src/utils/grog/grog.pl: Rename `tmac_ext` scalar to
+	`inferred_main_package`.
+
+2021-06-27  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/utils/grog/grog.pl (handle_args): Complain less noisily
+	and more comprehensibly when given unrecognized groff options.
+
+2021-06-27  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[grog]: Handle "--" argument as documented.
+
+	* src/utils/grog/grog.pl (handle_args): Rename scalar
+	`double_minus` to `no_more_options` so it actually communicates
+	something.  Drop openability check of operand encountered after
+	"--"; since it's on the operand list, it will be checked later
+	{in `handle_whole_files`}.  Stop pushing "--" itself onto the
+	`filespec` list.
+
+	Fixes <https://savannah.gnu.org/bugs/?60834>.
+
+2021-06-27  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[grog]: Revise operand handling, diagnostics, and exit status.
+
+	* src/utils/grog/grog.pl: Track more state so that we can
+	process the argument list more intelligently and exit with a
+	meaningful status.  Add `had_inference_problem`,
+	`had_processing_problem`, and `have_any_valid_args` Boolean
+	scalars.
+	(fail): Add diagnostic subroutine for serious problems; sets
+	`had_processing_problem`.
+	(handle_args, handle_file_ext): Stop complaining here about
+	unopenable file operands.
+	(handle_whole_files): Complain only here, with `fail` if a file
+	operand cannot be opened.
+	(make_groff_line_rest): Don't exit immediately if there is a
+	macro package inference clash, because there might be more
+	operands to process.  Instead, set `had_inference_problem`.
+	Stop exiting from this subroutine.
+	(top level): Only call the inference subroutines if we had a
+	valid operand to work with (including an implicit read from
+	stdin).  Exit with a status corresponding to the Booleans
+	declared above.
+
+	* src/utils/grog/grog.1.man (Exit status): Add section; describe
+	semantics of exit status values.
+
+	Fixes <https://savannah.gnu.org/bugs/?60833>.
+
+2021-06-27  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[grog]: Revise diagnostic messages.
+
+	* src/utils/grog/grog.1.man (err): Rename from this...
+	(warn): ...to this.  Prefix diagnostic with command name and
+	diagnostic severity level.  The subroutine didn't change the
+	exit status and was not used to report serious trouble, so
+	"warning" seems appropriate.
+	(make_groff_tmac_man_ms): Update call sites.  Modify diagnostic
+	wording to stop calling macros "requests".
+
+2021-06-27  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/utils/grog/grog.1.man (Limitations): Add subsection
+	covering the problem grog has with soelim inference.  Undocument
+	groff's -s option as one that can be inferred, because at
+	present it cannot be.
+
+	Prompted by Savannah #60421.

+
+2021-06-26  G. Branden Robinson <g.branden.robinson@gmail.com>

+

+
+	* src/utils/grog/tests/smoke-test.sh: Add test.

+	(TESTS): Add `grog_TESTS`.
+	(EXTRA_DIST): Ship test.
+
+2021-06-26  G. Branden Robinson <g.branden.robinson@gmail.com>
+

+
+2021-06-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/groff.texi (Assigning Formats): Revise discussion.
+	Clarify that a format never causes truncation of an interpolated
+	magnitude.  Note that non-Arabic number formats cannot be used
+	as operands to arithmetic expressions.  Add example of how to
+	work around this.
+
+2021-06-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[troff]: Clarify diagnostics.
+
+	* src/roff/troff/reg.cpp (reg::set_increment): Update diagnostic
+	to unabbreviate "auto".
+	(reg::alter_format): Update diagnostic to say "assign" instead
+	of "alter", since the documentation consistently uses the former
+	term.
+
+2021-06-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[troff]: Slightly refactor.  Make the source code slightly more
+	accessible by using a `bool` type for a member function's
+	default parameter used as a Boolean, and comment it at call
+	sites where the default is overridden.
+
+	* src/roff/troff/token.h (token::get_char): Change type of
+	parameter from `int` to `bool` and default from 0 to `false`.
+	* src/roff/troff/input.cpp (token::get_char): Update definition.
+	* src/roff/troff/env.cpp (hyphen_word):
+	* src/roff/troff/node.cpp (remove_font_special_character):
+	* src/roff/troff/input.cpp (do_overstrike, do_bracket, next)
+	(do_define_character, remove_character, get_line_arg)
+	(encode_char, do_if_request, do_translate, char_flags)
+	(hyphenation_code, define_class): Update call sites.  Add
+	comment indicating meaning of parameter.
+
+2021-06-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an-old.tmac (TH): When outputting HTML, write the
+	possibly case-transformed (but not yet abbreviated) page title
+	as the `title` element instead of the unaltered first argument
+	to `TH`.
+
+2021-06-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an-old.tmac (an-abbreviate-title): Define with `de`, not
+	`de1`, since it is not intended for call by traps or users.
+
+2021-06-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/groff.texi (Tab Stops): Fix erroneous claim; tab stops are
+	not set "every half inch across the page".  This is only true in
+	"line tabs mode", which is not enabled by default.  The default
+	behavior, to keep compatibility with AT&T troff, measures tab
+	stops relative to the current position on the input line.
+
+2021-06-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/mdoc/doc-nroff-u: Set the usekeeps register used by tbl
+	to the logical complement of the cR (continuous rendering)
+	register.  This prevents blank lines from creeping into tables
+	in that mode.
+
+2021-06-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an-old.tmac (an-blank-line-trap, an-leading-space-trap):
+	We say in a comment, "Macros ... that are called by traps of any
+	kind must be defined with `de1` because they might be called
+	from a context where compatibility mode is enabled."  So do it.
+
+2021-06-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an-old.tmac (an-header): Lightly refactor; tighten.
+
+2021-06-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an-old.tmac (an-write-paragraph-tag): Lightly refactor
+	for clarity and to reduce code duplicated in both branches of an
+	`ie`/`el` structure.
+
+2021-06-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an-old.tmac: Rename `an-HF-remap-I-style` register to
+	`an-remap-I-style-in-headings` for greater clarity.
+
+2021-06-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/mdoc/doc-common-u (doc-header, doc-end-macro): Partially
+	revert bf4b3dde (from 20 May); per Ingo Schwarze, continuous
+	rendering in mdoc(7) documents has always used only one vee
+	between headers, footers, and man page body text.
+
+2021-06-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/en.tmac: Stop using `do` request; it's unnecessary since
+	the file is already loaded with compatibility mode off.
+
+2021-06-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	[ms]: Fix doc omission; .ID can take an argument.
+
+	* doc/groff.texi (ms Document Control Settings) <DI>:
+	Characterize register setting as a _default_.
+	(ms Displays and Keeps): Add optional variable "indent" argument
+	to syntax summary of ".DS I" and ".ID".  Note that the given
+	indentation is used if present, and \n[DI] otherwise.
+	* doc/ms.ms (Displays and keeps): Add optional variable "indent"

+
+	* tmac/s.tmac: Properly situate devtag flag-related register

+	`s@devtag-needs-end-of-title`.
+	((initialization), par@reset, @SH, par@finish, @NH): Do it.
+	(par@reset): Test their values more idiomatically.

+
+2021-06-17  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/e.tmac-u (@h): Migrate SCCS revision 2.37 to be idiomatic
+	for groff (and not throw warnings of type 'mac').
+
+2021-06-17  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/doc.am: Improve diagnostics during documentation
+	generation; none should occur normally, but when they do, seeing
+	troff complain about "<standard input>" is disheartening.
+	(DOC_GROFF_ONLY): Add -b option so we get backtraces (also kill
+	off trailing whitespace).
+	(DOC_GROFF):
+	(doc/pic.html):
+	(doc/webpage.html): Add sed expression to inject `lf` request
+	into the stream to identify the file being processed.
+
+2021-06-17  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/me-revisions: Supplement history with subsequent BSD work
+	from versions 2.29 (1988-04-22) to 8.1 (1993-06-05).
+
+2021-06-17  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/me-revisions: Add 'me' macro package revision log, scraped

+	* doc/doc.am (DOCFILES): Ship it.
+
+2021-06-17  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/e.tmac-u: Rename registers for clarity.  Unlike other
+	macro packages supplied by groff, "me" mostly remains within the
+	AT&T 2-character name space, accessing extended names
+	selectively through `do` and `de1` requests.  The package
+	therefore has no characteristic name prefix.
+	  need_eo_h  -> devtag-needs-end-of-heading
+	  need_eo_tl -> devtag-needs-end-of-title
+	  need_tl    -> devtag-needs-title
+	(@html_check_need_title, sh, EQ): The foregoing registers are
+	effectively Booleans, so perform Boolean-style tests on their
+	interpolations.
+
+	Fixes a second third of <https://savannah.gnu.org/bugs/?42515>.
+
+2021-06-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/e.tmac-u: Work in compatibility mode.  It seems this was
+	the intention (reasonable, since "me" originates in pre-groff
+	BSD Unix), but there were several problems.
+	(@R): Prefix register existence test with `do`.
+	(@html_check_need_title): Define with `do` since the macro name
+	is long, and also with `de1` so that we can freely use groff
+	extensions within.  Drop many `do` requests from macro
+	definition.
+	(@check_need_title): Define with `do`, as above.  Add comment
+	explaining why `de1` is not needed for this macro definition.
+	(@S): Prefix macro/string existence test with `do`.  Remove

+
+	Indent an IP paragraph based on the type size of the paragraph
+	text, not a preceding heading.  We have to delay evaluating IP's
+	argument until the font size has been reset, which I've
+	attempted to do by simply passing the argument unevaluated down
+	the call hierarchy, instead of saving it in a number register
+	right away, as appears customary in this ms implementation.
+
+	However, par@reset is called from a great number of places, and
+	these usually set the indent registers beforehand.  I've left
+	this as it is, so now two ways of setting the indents exist: via
+	register and optionally via argument.
+
+	* tmac/s.tmac (par@reset): Move font-size setting stuff before
+	indent-setting stuff; set registers from optional arguments with

+	option flags for option arguments.
+	(help): Collate option flags in English lexicographic order.
+	Include space after flag letters for options that take
+	arguments.  Consistently use capitals for option arguments
+	because they are space-separated here.  Illustrate longer forms
+	of -d and -r options.  Update language (some, like "tmac.name",
+	was very old).  Add reference to groff(1) man page at end.

+	(initialization): Stop sourcing www.tmac.  Stop calling .LK and

+
+	[man]: Fix stochastic vertical space loss problems in continuous
+	rendering mode by being more scrupulous about extending the page
+	length.  As noted in Savannah #60611, sometimes the vertical
+	space between a header line and the first section heading
+	{"Name"} would be reduced or removed altogether, in a way that
+	was highly sensitive to circumstances.  As far as I can tell,
+	the problem is that this vertical space disappeared only when we
+	were in double-secret probation no-space mode; this is the
+	special non-spacing mode {not apparent with inspection of
+	\n[.ns]} that happens when the stealth internal page location
+	trap is sprung.  This trap does not appear in .ptr output but
+	can be disabled with ".vpt 0", which is an alternative fix for
+	this problem {because continuous rendering mode does not use
+	vertical position traps at all}.  Another fix might have been to
+	simply call the moral equivalent of ".pl MAXINT" as soon as
+	continuous rendering mode was decided upon.
+
+	* tmac/an-old.tmac (an-header): In continuous rendering mode,
+	extend the page length by one line before calling PT to output
+	the page header, and afterwards, extend the page length by 3

+
+	[man]: Fix missing page footers when continuously rendering
+	multiple documents.  Resolving this uncovered entangled header
+	and footer management bugs with batch processing even when _not_
+	continuously rendering.
+
+	* tmac/an-old.tmac (an-start-new-document): New macro clears
+	header trap so it doesn't get called with stale information.
+	{The TH macro already replants a header trap with every man
+	page if not continuously rendering.}  This macro also absorbs
+	the break-page and page number incrementation logic from TH.
+	(TH): Adapt semantics of "an-first" register to mean not "first
+	page rendered" (apparently) but "first page of new document".
+	If we are _not_ on the first page of a new document and the TH
+	macro is called, we must be batch processing: force the previous
+	man page to end (call an-end if continuously rendering, or
+	an-start-new-document if not).  After all the header and footer
+	strings have been configured for the man page, call an-header if
+	we're on the first page of the document, not (just) if we're
+	continuously rendering.  Zero an-first register at end of macro
+	here unconditionally instead of conditionally in .an-header.
+	(an-header): Drop conditional on continuous rendering.
+
+	When I batch-render our 62 man pages to the terminal, I do note
+	one cosmetic regression: the lj4_font(5) page, when continuously
+	rendered in batch processing, has no space between its header
+	line and first section heading ("Name").  Another cosmetic issue
+	in this scenario is that the footers for every rendered page but
+	the last, which had (wrongly) been absent entirely, are set with
+	no space after them and the header of the next.
+
+	* tmac/tests/an-old_page-footers-present.sh:
+	* tmac/tests/an-old_page-header-has-current-data.sh: Add man

+
+	* tmac/an-old.tmac (initialization): Key the reprocessing guard
+	{like a C language #include guard} on the existence of the TH
+	macro instead of RI.  The latter seemed kind of random and TH
+	is even more guaranteed to exist; it is the macro name most
+	characteristic of the man(7) language and the andoc.tmac
+	superstructure relies on it.  (TH may have been avoided because
+	of its use with tbl(1); however, neither man(7) nor mdoc(7)
+	support tbl's TH feature, and GNU tbl does not supply its own
+	empty fallback definition as it does for TS and TE.  If we ever
+	want TH-like functionality in future man pages, I suggest we
+	pick a new, non-colliding name for it.)
+	(initialization): Relocate load of devtag package; we don't
+	need it before entering compatibility mode.  Move assignment of
+	format of an-page-letter register from a "loose declaration"
+	amid macro definitions to within existence test of X register.
+	Stop initializing an-extra[123] strings outside of any macro;
+	they need to be reinitialized at every TH call when batch
+	rendering.
+	(TH): Call DT in a less surprising place.
+	(TH): Initialize all header/footer-related strings before
+	calling header macros, even those not needed for the default
+	header configuration.
+	(TH): Add style warnings for underspecified arguments.
+	(an-ne): Rename register from "an-need", which is pretty
+	confusing in context, to "an-amount", since (1) a (vertical)
+	amount is what it is, and (2) it's only used within this macro.
+	Also due to factor (2), remove the register after using it.

+	equivalent) font under all of the names recognized by
+	fonts/devpdf/Foundry.in.
+	* m4/groff.m4 (GROFF_URW_FONTS_CHECK): Update wording of notice
+	when URW fonts are not found.  Replace dead URL with working
+	one.  Try to hedge against the future, but the Web is an

+	fonts.  Thanks to T. Kurt Bond and Thomas Dupond for reporting

+

+	footnote numbers in nroff mode, inspired by Heirloom Doctools
+	ms; since superscripting is not universally available on
+	terminals, surround number with square brackets instead.
+	(fn@init): New macro finishes initializing footnote module,

+	and otherwise defining fn@sup-{start,end} as brackets.  Define *
+	string here, using new strings.

+
+	* test-groff.in: Stop passing the built groff executable -b and
+	-ww options by default.  This reverses a change from 2017.  Dave
+	Kemper has convincingly argued that there's no way to override
+	-b and turn backtraces on warnings/errors back off, and that the
+	built groff should behave as much like a "normal" one as

+	long input line in troff implementation.  If not in troff mode,
+	use ISO 6429 color escapes to render boxed text in black on

+
+	* tmac/an-old.tmac (SH): Fix apparent thinko.  Pass the devtags
+	macro a literal "1" argument.  Passing it \n[an-level] wasn't
+	correct (it stores the relative inset level, not a sectioning
+	level), and was useless anyway: SH has already called
+	.an-set-margin by this point, which resets \n[an-level] to 1.

+
+	Implement new .soquiet and .msoquiet requests.
+
+	Needed for two planned developments: {1} the i18n patch in
+	Savannah #59814 can use this to quietly attempt to open a
+	localization file.  groff only supports a few locales, so people
+	with LANG=es_ES, for instance, would ordinarily see warning
+	diagnostics on every groff startup; and {2} system- or
+	site-configurable support of per-user {.,}troffrc or man.local
+	files, gracefully failing if they don't exist.
+
+	* src/roff/troff/input.cpp:
+	(do_source): Add new function, taking boolean "quietly"
+	parameter and absorbing function of source(), with added
+	conditional.
+	(source): Convert into a wrapper to call do_source() unquietly.
+	(source_quietly): Wrap do_source(), quietly.
+	(do_macro_source, macro_source, macro_source_quietly): Analogous
+	to the foregoing.

+
+	* doc/groff.texi (Manipulating Hyphenation):
+	Recast introductory paragraph to better distinguish the
+	automatic breaking of words and placement of hyphens at
+	user-specified hyphenation points (done with the \% escape) and
+	automatic determination of hyphenation points within words (what
+	the pattern files and most of the hyphenation mode parameters
+	are for).  Clarify that what our manual calls "automatic
+	hyphenation" pertains only to the latter.
+	<hw> Correct over-general claim; hyphenation exceptions defined
+	with the .hw request _do_ honor .hy value 2 (don't break a word
+	at the bottom of a page), but none of the others.
+	<\%> Recast description of escape to emphasize independence of
+	its two uses (e.g., "\%pseudo\%unununium" is hyphenated only
+	after "pseudo-", if at all).
+	<\:> Clarify that escape is an input word boundary.
+	<shc> Clarify that the soft hyphen glyph is applied to manual as
+	well as automatically-determined hyphenation points.
+	<hy> Recharacterize as setting the _automatic_ hyphenation mode.
+	Note that restrictions apart from value 2 are not applied to
+	words with manually-assigned hyphenation points.
+	<nh> Note that request affects only automatic hyphenation.
+
+	* man/groff.7.man (Requests/Request short reference) <.hy,.nh>:
+	Clarify that requests deal with _automatic_ hyphenation.
+	(Registers/Read-only registers) <.hy>:
+	Clarify that register applies to _automatic_ hyphenation.
+	(Hyphenation): Add new introductory paragraph summarizing manual
+	hyphenation support and features, including notice that breaking
+	at explicit hyphens is performed in fill mode, i.e., even if
+	_automatic_ hyphenation is disabled.
+

+	some C library implementations, including recent versions of
+	glibc[2], lack this property.  free() is called in these
+	libgroff functions to clean up after an unsuccessful fopen() of
+	a heap-allocated file name string, and because the errno from

+	* contrib/glilypond/glilypond.pl:
+	* contrib/gperl/gperl.pl:
+	* contrib/gpinyin/gpinyin.pl:
+	* tmac/hyphenex.pl: Avoid Perl's unsafe "<>" operator.
+
+	The "<>" operator is implemented using the two-argument form of
+	"open", which interprets magic such as pipe characters, allowing
+	execution of arbitrary commands which is unlikely to be
+	expected.  Perl >= 5.22 has a "<<>>" operator which avoids this,
+	but also forbids the use of "-" to mean the standard input,
+	which is a facility that the affected groff programs document.
+
+	ARGV::readonly would probably also fix this, but I fundamentally
+	dislike the approach of escaping data in preparation for a
+	language facility to unescape it, especially when the required
+	escaping is as non-obvious as it is here.  (For the same reason,
+	I prefer to use subprocess invocation facilities that allow
+	passing the argument list as a list rather than as a string to
+	be interpreted by the shell.)  So I've abandoned this dubious
+	convenience and changed the affected programs to iterate over
+	command-line arguments manually using the three-argument form of
+	open.
+
+	glilypond doesn't need the initial unshift since that's already
+	handled in contrib/glilypond/args.pl.

+
+	Document use of SOURCE_DATE_EPOCH and TZ.
+
+	The semantics of SOURCE_DATE_EPOCH to groff were not established
+	with respect to time zone selection, prompting divergent
+	interpretations; Debian and distributions derived from it have
+	for several years patched groff to implicitly use UTC as the
+	time zone when interpreting the current time (or
+	SOURCE_DATE_EPOCH) as a local time.  While a convenient and
+	defensible choice for reproducible build efforts[1], it runs
+	against the grain of user expectations.  Systems programmers
+	like monotonically increasing clocks; the broader user base
+	usually prefers a clock that follows an applicable civil
+	calendar.  To the latter audience, a difference between
+	  $ date "+%Y-%M-%d %H:%m:%S"
+	and
+	  $ groff <<EOF
+	  .af year 0000
+	  .af mo 00
+	  .af dy 00
+	  .af hours 00
+	  .af minutes 00
+	  .af seconds 00
+	  .tm \n[year]-\n[mo]-\n[dy] \n[hours]:\n[minutes]:\n[seconds]

+	Measure the string before and after calling .substring on it,
+	and break out of loop if it didn't get shorter.

+
+	* src/roff/troff/div.cpp (top_level_diversion::change_trap):
+	Emit error diagnostic if an attempt is made to move an unplanted
+	macro.  This could have been a warning, as it's pretty harmless
+	{though possibly a big surprise to anyone who was wondering why
+	their .ch was a no-op}, but there's no good warning category for
+	this kind of problem and I am not about to start a bike shed
+	discussion about it right now.
+
+2020-11-15  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/groff.texi: Update.  Add introductory material.  Rewrite
+	the first section of the "gtroff Reference" chapter of our
+	Texinfo manual.  It is written as an introduction for readers
+	who want to go straight to "raw" troff without knowing much or
+	anything about existing macro packages.  Thanks to Dave Kemper
+	and John Gardner for feedback and support.
+
+	Clarify whitespace usage.  "Whitespace" is defined in this
+	manual as "spaces, tabs, and newlines".  Say only "spaces and
+	tabs" when newlines should not be included.
+
+	Rename "Font Files" to "Device and Font Files".
+
+	Rename "Manipulating Filling and Adjusting" to "Manipulating
+	Filling and Adjustment".
+
+	Update discussion of "copy mode".  Rename from "copy-in mode",
+	which I don't think eludicdated anything; is there a "copy-out
+	mode"?  Rename nodes accordingly.  Attempt to explain more
+	clearly.  Recast to shift emphasis to what _isn't_ merely copied
+	in copy mode, since that is what seems to cause confusion among
+	the inexperienced.
+
+	Update "Conditionals and Loops".  Add introductory paragraph.
+	Add nodes/subsections "if-then" and "Conditional Blocks".  Add
+	subsection "Conditional Blocks" to explain the behavior of the
+	\{ and \} escapes much more precisely.  I don't think this
+	syntactical area is well understood.  Supply examples.

+
+	Not otherwise documented yet; experimental--subject to change.

+	them empty or zero if they are not set).  This reserves them so
+	that they don't become used for divergent purposes.  man(1)

+
+2020-10-30  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/s.tmac: Revise diagnostic messages.  Define a common
+	prefix string, starting all such messages with "s.tmac".
+	Continues the long process of fixing Savannah #52463.  Drop the
+	word "macro" from diagnostic since this will now be clear from
+	the prefix.  Prefix every macro name in a diagnostic message
+	with a leading dot; this was already done in four cases.
+	(cov*first-page-init): Use temporary string to avoid multi-line
+	diagnostic message.
+	(@NH): Use temporary string to prevent overlength line.
+
+	A further benefit of this revision is that index information
+	produced by ms's .IX macro (which writes to the standard error
+	stream) will now be trivially easy to extract even for documents
+	that cause diagnostic messages.  One can simply filter them with
+		grep -v '^s\.tmac:'
+	or similar.

+
+	Fix ms .TC macro by allowing it to actually use lowercase Roman
+	numerals for the page(s) of the table of contents when a custom
+	title (header or footer) is defined containing '%'.
+
+	As a side effect, eliminate the PN register, which was
+	apparently misused because it was undocumented and had a name
+	just long enough to be both suggestive and ambiguous.  Another
+	pin goes into my Ken Thompson voodoo doll.
+
+	* tmac/s.tmac (IX): Write out page number of index term(s) using
+	the % register (instead of PN), obtaining whatever format is
+	assigned to the register at that time.
+	(CH): Similarly, output %, not PN, in the center of the default
+	heading.
+	(PT): Save the format of %, set it to decimal, copy its value to
+	a new register, pg*page-number-in-decimal, then restore %'s
+	previous format.  Compare the new register, not %, to 1 to
+	determine whether special page one behavior should be used.
+	(pg*end-page): Assign pg*next-format to %, not PN.

+	* tmac/an-old.tmac: Add fallback for lq, rq strings.
+
+	Define \*(lq and \*(rq as '"' if the output device has no \(lq
+	or \(rq special character escapes defined (respectively).
+
+	This is a bit belt-and-suspenders for groff since our output
+	devices all guarantee availability of these glyphs, but if this
+	macro file gets used with other implementations (and if they
+	support the 'c' conditional), it should prevent the strings from
+	producing empty output.
+
+	Man page writers should simply use \(lq and \(rq unless they are
+	aiming for pathological levels of portability (e.g., composing
+	man pages today for consumption on simulators of 1980s Unix
+	systems).
+
+2020-10-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an-old.tmac: Define an-end with .de1.  We need to define

+	place.  However, there are other ways the conditional can be
+	satisfied, as witnessed in Savannah #57665, so simply say what

+	trap (we say the row won't "fit on [the] page").

+	1995).  Did you notice a two-font macro missing?  It was: IR.

+	and avoid a forward reference and scattering of \n[cR]

+
+	* tmac/an-old.tmac: Drop .ll hack for LL register.
+
+	Drop the .ll hack for setting the line length on nroff devices.
+
+	Once upon a time, the only way to get man pages to render on a
+	terminal at any width other than the nroff default of 65n was to
+	put an .ll request into the page--a mortal sin against
+	portability--or your man(1) program could sneak such a request
+	into nroff's input stream.
+
+	Also, long ago, John Eaton of UT Austin wrote a man(1) program.
+	In a few years this implementation branched into two lines of
+	development, which I'll call man-db man (Wilford/Polacco/Watson)
+	and another, Brouwer/Lucifredi man, which as of this writing saw
+	its last release in 2011 (1.6g).
+
+	The man and mdoc macros of groff 1.18 (July 2002) introduced an
+	LL register to configure the line length, respecting an -rLL
+	command-line option.  The source change was made by Werner
+	Lemberg on 3 May 2002 and Colin Watson updated man-db man(1)--on
+	the same day!--to synthesize the option when calling groff.
+
+	Later, in August 2005, Keith Marshall, a user of version 1.5m of
+	Brouwer/Lucifredi man(1), which did not set the LL register,
+	suggested that the existing .ll setting (technically, the value
+	of \n[.l], the only way the result of an .ll request could be
+	introspected) be honored in the absence of the LL register.
+	However, it is impossible to distinguish a user-supplied ".ll
+	65n" request from nroff's default setting, which was in that
+	case overridden to the modern default of 78n.
+
+	And so, in what is now git commit
+	f9d5df4aebd3d834b4084ffefa52a115e00dce38 (1 September 2005), it
+	was done.
+
+	This led to (1) surprising behavior for users accustomed to old
+	methods and desirous of the nroff default and (2) lengthy
+	apologia in groff source code comments and the groff_man(7) man
+	page.
+
+	Ironically, Brouwer/Lucifredi man(1) had already added support
+	for the LL register by the time of its 1.6 release two months
+	earlier (20 June 2005).  (Curiously, it did so similarly to the
+	old .ll hack, by injecting an '.nr LL' request into groff's
+	input stream, rather than using the -r command-line option.)
+	Moreover, Marshall and the groff list were already aware of
+	this, but the change was accepted anyway because version 1.6
+	was "too new"!  (Distributions are slow sometimes, true...)
+
+	Let us survey the field in 2020.  man-db man(1) has supported
+	the LL register for eighteen years, and Brouwer/Lucifredi man(1)
+	for fifteen.  Heirloom Doctools's man macros set the line length
+	to 78n on nroff devices unconditionally.  mandoc(1) similarly
+	also always formats for 78 columns on terminals.  groff's
+	mdoc(7) macros grew support for LL in parallel with man(7) in
+	2002 and never added the \n[.l] introspection at all.
+
+	There no longer seems to be any reason to preserve this hack.
+
+	* tmac/an-old.tmac (initialization): Drop complex setup of LL
+	register.
+	(TH): Relocate line length reset; no behavior change.
+	(after .mso man.local): Initialize LL only if the user hasn't;
+	use device default in troff mode, and 78n in nroff mode.

+
+	* makevarescape.sed: Use \[] form of special character escapes.
+
+	The only man page we have that doesn't turn compatibility mode

+	likely to be used.
+
+	The @g@ command prefix is the main avenue for intrusion of such
+	escapes, but I think it improbable that many people are going to
+	include apostrophes, double quotes, carets, grave accents, or
+	tildes in the command prefix; some or all of these will pick
+	fights with the shell and require quoting that we don't
+	represent in man page text anyway.
+
+	On top of that, neqn is largely a stub page.
+
+	If it's a problem, a better fix than reverting this is to make
+	neqn switch out of compatibility mode like our other man pages.

+
+	mdoc: Relocate within build tree.
+
+	The (modern) mdoc macro package has not been usable within the
+	build tree, unlike the others.  This makes it more troublesome
+	to test changes, and frustrates deploying our test
+	infrastructure against it.  Re-arrange the build tree to
+	resemble an installation tree closely enough for the macro
+	package to load.

+2020-08-22  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an-old.tmac (TH): Set hyphenation mode to user preference
+	with each new page rendered, in case a hostile page meddled with
+	'.hy' or '.nh'.
+	(after .mso man.local): Relocate setting of default hyphenation
+	mode here (instead of just before .mso man.local).  Eliminate
+	conditional on \n[an-html]; this doesn't matter because
+	grohtml(1) doesn't support hyphenation anyway.  If it does learn
+	to hyphenate, we should treat it the same as other output
+	devices in any case.  Add comment explaining why we fall back to
+	different defaults depending on \n[cR].
+
+2020-08-22  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an-old.tmac (TH): Set adjustment to user preference with
+	each new page rendered, in case a hostile page meddled with
+	'.ad' or '.na'.
+	(after .mso man.local): Set the default adjustment mode only if
+	a -d option or man.local did not.  Also do the same for the HF
+	string; relocate its definition here and make it similarly
+	conditional.  Also update comment on setting of CS and CT
+	registers and style their conditionals consistently with the
+	rest of the package.
+
+	* tmac/groff_man.7.man.in (Strings) <\*(AD>: Document it.
+	(Strings) <\*(HF>: Parallelize language with new \*(AD.
+	(Options) Expand introductory sentence to discuss -d and -r
+	options.
+	(Options) <-dAD>: Document default and likely values.  Nobody
+	right-justifies or centers man page text; send the curious to
+	groff(7) for '.ad' request documentation.

+
+	* tmac/an-old.tmac (set-an-margin): Rename...

+2020-08-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+

+	* tmac/tmac.am (tmac_XFAIL_TESTS): Mark the punctuation
+	hyphenation tests as expected to fail, because they now do.
+
+2020-08-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/ps.tmac: Define ordinary hyphen-minus as fallback
+	character for U+2011 (non-breaking hyphen).  Prompted by
+	discussion with Dave Kemper in Savannah #58390.
+
+2020-08-15  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Fix hyphenation bug.  The UR/UE and MT/ME macros were much too
+	aggressive about turning hyphenation off.  Disable it only when
+	writing the actual URL or email address.
+
+	* tmac/an-ext.tmac (.MT, .UR): Stop disabling hyphenation here.
+	(.ME, .UE): Disable hyphenation right before output of
+	URL/address; restore it right before output of supplementary
+	arguments ("punctuation").
+

+
+2020-08-15  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Adapt to the fact that \: reënables hyphenation.  Rename
+	"hyphenless [discretionary] break" to "non-printing break point"
+	in documentation.
+
+	* doc/groff.texi (Manipulating Hyphenation): Rename "hyphenless
+	break" to "non-printing break point".  Clarify that it is the
+	soft hyphen glyph, not necessarily a hyphen, that is ordinarily
+	written to the output on hyphenation breaks.  Note that the
+	remainder of a word after \: is subject to hyphenation as
+	normal.  Note (new) '\:\%' idiom for getting what people will
+	want at least some of the time.  Update example to use it.
+	* makevarescape.sed: Insert \% after we insert \: to rewrite
+	slashes in filenames, to protect later portions of the filename
+	from hyphenation.
+	* man/groff.7.man (Escape Sequences/Escape short reference):
+	Rename "hyphenless break" to "non-printing break point".
+	* man/groff_diff.7.man (Language/Escape sequences): Resync with
+	our Texinfo manual.
+	* tmac/groff_man.7.man.in (Description/Hyperlink and email

+	(Ligatures and kerning): Update conceptual index entries.
+	Supply context ("effect on kerning").
+	(Drawing requests): Update conceptual index entries.  Supply

+
+	* tmac/groff_man.7.man.in (Description/{Document structure
+	macros <.TH>, Horizontal and vertical spacing}): Fix erroneous
+	use of "flush left".  The current uses were introduced by me,
+	but the page has borne incorrect uses of it as far back as 1999
+	{in the description of .TP}.  Simply say "with no indentation"
+	instead.
+
+2020-08-13  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/groff_man.7.man.in (Description/Number registers): Inform
+	reader that registers can be set in man.local file and
+	cross-reference it.
+	(Files/*/man.local): [style] Supply example of man.local
+	customizations, prompted by recent discussions on groff,
+	linux-man, and man-db mailing lists.
+
+2020-08-12  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/tmac.am: Use a stamp file for m4 keyword check.
+	(M4CHECK): Add stamp file variable.
+	($(M4CHECK)): Create stamp file if check succeeds.
+
+2020-08-12  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Split groff_man(7) into two pages; one a (relatively) terse
+	reference and the other a tutorial and style guide.  Both are
+	generated from the same source, which is processed by m4 into
+	two man page sources.
+
+	* tmac/groff_man.7.man: Rename...
+	* tmac/groff_man.7.man.in: ...to this.
+
+	* tmac/groff_man.7.man.in: Add m4 directives and define macros.
+	Protect m4 keywords in English from unintended expansion (this
+	affected the word "include").  Add new .TH and apropos lines for
+	style guide.  Convert marker comments into m4 macros for content
+	control.  Uncomment material intended only for basic reference
+	page.
+
+	* tmac/tmac.am (man7_MANS): Add groff_man_style.7.
+	(EXTRADIST) Add groff_man.7.man.in.
+	(MOSTLYCLEANFILES): Add m4-generated man page sources
+	tmac/groff_man{,_style}.7.man.
+	Add targets to generate those same two pages from the renamed
+	file.  Add target to grep the page for unprotected English m4
+	keywords and halt the build if they are found.  Make generation
+	of those pages depend on this new target.
+
+2020-08-11  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/groff_man.7.man: Add material on hooks and encoding.
+	(Description, ./Deprecated features): Stop identifying .PT and
+	.BT as "deprecated"; they shouldn't ever be called in man pages,
+	but that has never been their intention.
+	(Description): Identify character encoding and line-ending
+	requirements (tutorial/style-guide material).
+	(Description/Hooks): Add new subsection to house descriptions of
+	.PT and .BT.  Add mnemonic expansions for both.
+
+2020-07-31  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* man/groff.7.man (Control Characters): Incorrect claims were
+	made.  Double quotes can indeed be used to enclose arguments to
+	string interpolations.  The statement about a leading " in a
+	string definition (or appendment with .as) was stated too
+	generally.  The leading quote is not necessary to include
+	leading tab characters, which can be input as-is, even in
+	compatibility mode.
+
+2020-07-28  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* man/groff.7.man (Requests/Request short reference/.ft): Fix
+	some outright damage in the description of the request; the
+	escape sequences that are synonymous with a nullary .ft had been
+	wrongly removed.
+
+2020-07-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/meintro.me:
+	* doc/meref.me:
+	* tmac/e.tmac-u: Remove postal address for Eric Allman.  It's
+	probably decades out of date.  Adjust footnote symbols.  Thanks

+	<https://savannah.gnu.org/bugs/?58726>.
+
+2020-07-23  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Migrate macro packages from font CW to CR.  The font name "CW"
+	{"constant-width"} is a legacy item we can dispose of (except
+	for the DVI device, which also has CWI for "constant-width
+	italic"), and much of the groff codebase already did starting
+	with commit 0de1d6d79cdb959ffa7dac3af77c2a36ef31873f {October
+	2017}.  Courier is available in the usual four styles {roman,
+	bold, italic, bold+italic}.
+
+	* tmac/an-ext.tmac (.EX): Set font to R, not CW.  The existing
+	.ft request was somewhat redundant with the '.do fam C'
+	immediately before, which set the font family to Courier.
+	* tmac/s.tmac (.UC): Use font CR, not CW.
+
+2020-07-23  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/tty.tmac: Stop suppressing nonexistent font warning.
+	Prompted by a 2017 suggestion and patch from Bjarni Ingi
+	Gislason.  Documents and macro packages that want to change the
+	font family should do so in awareness that this is meaningless
+	on terminal (nroff) devices (and -Thtml as well).
+
+	Fixes <https://savannah.gnu.org/bugs/?51364>.
+
+2020-07-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/groff_man.7.man (.PP, .LP, .P): Fix error: these macros
+	do not reset the left margin.
+
+2020-07-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/groff.texi (Strings): Document behavior of .ds request
+	when only one argument is supplied.  (The string is defined as
+	empty.)  Thanks to Dave Kemper for the report and the patch.
+
+	Fixes <https://savannah.gnu.org/bugs/?58746>.
+
+2020-07-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/groff.texi (Using Symbols): Fix error in .rfschar
+	description, which should refer to "font f" rather than "glyph
+	f".  Thanks to Dave Kemper for the report and the patch.
+
+	Fixes <https://savannah.gnu.org/bugs/?58767>.
+
+2020-07-12  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/groff_man.7.man (.EE, .YS): Fix error: refer to "initial
+	hyphenation setting" instead of "previous hyphenation mode".
+	Incidentally, this fact points out why putting ".hy 0" or ".nh"
+	in your man page is futile.
+
+2020-06-28  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* man/groff.7.man (Requests/Request short reference): Fix error
+	in description of .hc; it changes the hyphenation character
+	rather than supplying an additional one.
+
+2020-06-12  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/groff.texi (Groff Options): Remove editorial comment about
+	'-a' option being "useless".  It isn't.  Update example for
+	contemporary systems (like Debian) and to reflect the fact that
+	the GNU troff(1) man page needs to be preprocessed with tbl(1).
+	(Invoking grotty): Recast discussion of -c option, importing
+	much language from grotty(1) page rewrite from a year ago.  Add
+	program index entries for col, more, and ul.  Fix transposition
+	error in ISO document number.
+
+	* src/devices/grotty/grotty.1.man (Description/Legacy output
+	format): Make slight wording changes prompted by content of
+	parallel section in our Texinfo manual.
+
+	* src/roff/groff/groff.1.man (Options/-a): Parallelize with
+	first sentence of corresponding material in our Texinfo
+	manual.
+
+	* src/roff/troff/troff.1.man (Options/-a): Parallelize with

+

+
+2020-06-12  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* man/groff_diff.7.man (Language/Long names): Fix error: groff
+	adds three new requests with short names, not two.  List them in
+	an adjacent comment.
+
+2020-06-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an-ext.tmac (.ME, .UE): Fix portability issue.  While
+	widely supported, the \$* escape is not documented in CSTR #54.
+	If groff is not the typesetter, append macro arguments using
+	\$1, \$2, ..., \$9 instead.
+
+2020-05-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* man/groff.7.man (Numerical Expressions): Fix error: negative
+	expressions evaluate false, not true as was implied.
+	Parallelize descriptions with our Texinfo manual and
+	groff_diff(7) (in abbreviated form).
+
+2020-05-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/groff.texi (Manipulating Filling and Adjusting): Fix error

+
+2020-05-14  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/preconv/tests/smoke-test.sh: Make BOM detection
+	override less hinky (i.e., use more normative input).  Add tests
+	for all five detected BOMs.
+
+2020-05-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/roff/troff/env.cpp (space_size): Prevent assertion
+	failure.  If an argument to the .ss request is negative, throw a
+	range warning and ignore it.
+	* src/roff/groff/tests/regression_savannah_58337.sh: Add test.
+	* src/roff/groff/groff.am (groff_TESTS): Run test.

+2020-05-08  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Update documentation of .ss request.
+
+	* doc/groff.texi (Manipulating Filling and Adjusting): Rewrite
+	documentation of .ss request and \n[.ss] and \n[.sss] escapes.
+	Note that negative values are not permitted in either argument
+	to .ss.  Use new terminology, "minimal inter-word spacing" and
+	"additional inter-sentence spacing" for clarity.  Clarify that
+	additional inter-sentence spacing is only used when the output
+	line is not full when the end of a sentence occurs.  Add index
+	nodes to help readers find discussion of details of spacing
+	between words and sentences.  Move discussion of differences
+	from AT&T troff to section "Implementation Differences".  Update
+	example to more closely resemble a real-world case, use second
+	argument to .ss request, and eliminate hackish use of .nop
+	request.
+
+	* man/groff_diff.7.man (New number registers): Recast in
+	parallel with the foregoing.
+
+	* man/groff.7.man (Read-only registers): Use new terminology and
+	describe \n[.ss] and \n[.sss] in meaningful terms, not by
+	reference to arguments to the .ss request (which wasn't even
+	accurate, because these registers have default values).
+
+	Fixes https://savannah.gnu.org/bugs/?54101.

+
+	Undocument plans to support end-of-file GNU Emacs coding tags.
+
+	* src/preproc/preconv/preconv.cpp (check_coding_tag):  Update
+	comments.
+	(detect_file_encoding): Alter debugging output so it's easier to
+	grep and verify Emacs coding tag detection.
+
+	* src/preproc/preconv/preconv.1.man (Bugs): Delete; its sole
+	concern was the absence of this feature.
+	(Usage): Document detection algorithm in more detail.  Note
+	which detection methods don't work on unseekable input (pipes).
+	Offer recommendations for those struggling with encoding
+	detection.
+	(Usage/Coding Tags): Stop manipulating line adjustment.  Use
+	hyphen-minus (\- escape) characters in coding tag names, since
+	they are literals that one might copy and paste.  Stop
+	referencing XEmacs, whose development appears moribund.
+	(See Also): Add cross-references to iconv(3) and locale(7) man
+	pages.
+
+	* src/preproc/preconv/tests/smoke-test.sh: Test each of the
+	steps in the detection algorithm.

+
+	* man/groff_diff.7.man (Implementation Differences): Document

+
+	* src/utils/addftinfo/addftinfo.cpp (usage):
+	* src/utils/tfmtodit/tfmtodit.cpp (usage): Add "usage:" prefix
+	to messages documenting auxiliary modes of invoking the program.
+	The output doesn't look right without one, and it feels
+	dishonest to not document the relevant options (-v, --version)
+	disjunctively.  I'm trying to strike a balance between the
+	ultra-terse BSD approach and the ultra-garrulous GNU one (see,
+	e.g., ls(1)).  Likely both camps will be unhappy.  :-/
+
+2020-04-30  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/utils/tfmtodit/tfmtodit.cpp (read_map): Report invalid
+	character code from map file in diagnostic.
+	(main): Report invalid skew character position in diagnostic.
+	Explicitly report insufficient arguments in addition to usage
+	message.  Lift invariant computed expressions out of loops (more
+	to shorten long lines than because I think the compiler won't
+	figure it out).  Give content to "impossible assertion".
+	(tfm::load): Capitalize TFM initialism in diagnostics.
+	(usage): Use full capitals for parameters as is conventional.
+	Document disjunction of -v/--version flag from other
+	invocations.
+
+2020-04-29  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/utils/addftinfo/addftinfo.cpp (usage): Add overloaded
+	version that accepts a constant string argument, which emits the
+	argument as a diagnostic and then calls usage().
+	(main): Add diagnostics to usage message where the problem is
+	clear.  Add comment explaining why it sometimes isn't.
+	(usage): Refactor main usage message (which prints the summary)
+	to report the actual names of the accepted option arguments
+	instead of just "-param", which is not literally accepted.
+
+	Sort param_table alphabetically for use by the usage message.

+
+	Implement new read-only .cp register.
+
+	Within a .do request, \n[.cp] holds the saved value of
+	compatibility mode.
+
+	The register \n[.cp] is specialized and may require a statement
+	of rationale.  When writing macro packages or documents that use
+	groff features and which may be mixed with other packages or
+	documents that do not—common scenarios include serial processing
+	of man pages or use of the .so or .mso requests—you may desire
+	correct operation regardless of compatibility mode in the
+	surrounding context.  It may occur to you to save the existing
+	value of \n(.C into a register, say, _C, at the beginning of
+	your file, turn compatibility mode off with “.cp 0”, then
+	restore it from that register at the end with “.cp \n(_C”.  At
+	the same time, a modular design of a document or macro package
+	may lead you to multiple layers of inclusion.  You cannot use
+	the same register name everywhere or you risk “clobbering” the
+	value from a preceding or enclosing context.  The two‐character
+	register namespace of AT&T troff is confining and mnemonically
+	challenging; you may wish to use groff's more capacious
+	namespace.  However, attempting “.nr _my_saved_C \n(.C” will not
+	work in compatibility mode; the register name is too long.
+	“This is exactly what .do is for,” you think, “.do nr
+	_my_saved_C \n(.C”.  The foregoing will always save zero to your
+	register, because .do turns compatibility mode off while it
+	interprets its argument list.  What you need is:
+		.do nr _my_saved_C \n[.cp]
+		.cp 0
+	at the beginning of your file, followed by
+		.cp \n[_my_saved_C]
+	at the end.  As in the C language, we all have to share one big
+	namespace, so choose a register name that is unlikely to collide
+	with other uses.

+	Make our assert() C99-conformant.
+
+	groff has its own implementation of the standard C library's

+
+	Enable backtracing across process/file boundaries when errors or
+	non-ignored warnings are encountered.
+
+	Experimentation reveals that .so, .mso, and .pso requests acted
+	as barriers to backtracing except when explicitly requested with
+	the .backtrace request.  Judging by the git history, this
+	behavior dates back to June 1991 or earlier.  The intention,
+	according to a source comment, was only to suppress the
+	backtrace output for the line corresponding to the outermost
+	level of the input stack (commonly, a file argument to groff).
+	Unfortunately, that wasn't its only effect.
+
+	This change does result in one additional line of output for
+	each error or (non-ignored) warning when -b is given.  However,
+	I regard this as unobjectionable because {1} a backtrace was in
+	fact explicitly requested; and {2} it seems a poor tradeoff to
+	suppress most of the backtrace in some complicated and
+	frustrating cases for the sake of one fewer line of backtrace
+	output in a trivial one.
+
+	Now, backtracing behaves the same no matter what triggers it.
+
+	Fixes Savannah #58153.
+
+	* src/roff/troff/input.cpp (file_iterator::backtrace): Call
+	get_location() for its side effect of rewriting a filename of
+	"-" to "<standard input>", for consistency with other diagnostic
+	messages.  (In this class, this member function always returns
+	1, so ignore the return value.  This fact is an essential part
+	of what led to the bug; the conditional
+		p && !p->get_location(0, &f, &n)
+	which appeared in the for loop of input_stack::backtrace() prior
+	to this change would always evaluate to false when a node of the
+	file_iterator class was encountered.)
+	(input_stack::backtrace): Replace member function body with that
+	of input_stack::backtrace_all().
+	(input_stack::backtrace_all): Delete.
+	(backtrace_request): Update the only call site of the above.

+
+	Reorganize backtrace output.
+
+	* src/roff/troff/input.cpp (string_iterator::backtrace):
+	Prefix the output with the program name if it is known.  In a
+	deviation from the GNU Coding Standards, put the string
+	"backtrace:" immediately next instead of the file and line
+	number; this is because, particularly in cases where the
+	backtrace is most interesting or needed, it will produce
+	multiple lines of output and the common prefix aids visual
+	understanding.
+	(file_iterator::backtrace): As above; also, change prefix for
+	popened nodes in the iterator from "process" to "pipe".  This
+	seemed preferable to omitting the information entirely or using
+	an inscrutable sigil like 'f' or 'p'.  The advantage is that the
+	output is better aligned--better ergonomics for those who have
+	to cope with a lot of it.  Furthermore, output the filename only
+	once.
+
+	Example of old and new output:
+
+	/tmp/inner:2: backtrace: file '/tmp/inner'
+	echo .so /tmp/inner:1: backtrace: process 'echo .so /tmp/inner'
+	/tmp/outer:1: backtrace: file '/tmp/outer'
+
+	troff: backtrace: file '/tmp/inner':2
+	troff: backtrace: pipe 'echo .so /tmp/inner':1
+	troff: backtrace: file '/tmp/outer':1

+
+	* src/roff/troff/input.cpp (read_size): Add units to diagnostic.
+	This function works only with device-specific basic units
+	internally; users likely think in terms of point size, so add
+	the basic unit suffix "u" to offer a hint about what's going on.
+
+	Example:
+	$ groff -ww >/dev/null
+	\s[10]A\s[-12]B
+	troff: <standard input>:1: warning: point-size escape results in
+	non-positive size -2000u; set to 1u
+
+	On a PostScript device with 1000 basic units to the point, the
+	difference is important and would be confusing without the unit
+	indication.
+
+2020-04-08  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Correct and clarify point size documentation.
+
+	Our Texinfo manual has long documented the request '.ps 0' as
+	restoring the previous point size (just as '\s0' or '.ps' with
+	no argument does), but this is incorrect; since groff 1.02 or
+	earlier (June 1991), the request has not actually worked this
+	way.  Instead, '.ps 0' sets the point size to 1 basic unit
+	{though output drivers may clamp this to a higher value}.  This
+	behavior is consistent with AT&T troff, Hierloom Doctools troff
+	and, per Ingo Schwarze, Plan 9 troff.  (It is, however, not
+	consistent with neatroff.)
+
+	* doc/groff.texi (Changing Type Sizes): Stop claiming that '.ps
+	0' works like '\s0'.  Note that the resulting (computed) point
+	size, not the argument, is clamped.  Note that it is
+	non-positive, not negative, point sizes that are clamped to 1u.
+	Add (forward) cross-reference to section where \n[.ps] is
+	defined since it is mentioned here.  Move explanation of special
+	handling of zero argument to \s escape description.
+
+	* man/groff.7.man (Request short reference): Explain .ps N
+	independently of \s.  Note clamping behavior.

+
+2020-04-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/roff/troff/input.cpp (read_size): Move special-case
+	interpretation of the '\sN' form of point-size escapes when 'N'
+	is 1, 2, or 3 to compatibility mode (groff -C) only, and throw
+	error diagnostic with suggestion for remedy if encountered.
+
+	Traditionally, '\s36A' is interpreted as "set point size to 36,
+	then emit 'A'".  However, only values in the range 10-39 are
+	handled specially; '\s40A' is interpreted as a four-point "0A".
+	This is unlike anything else in *roff grammar; see \*, \$, \f,
+	\F, \g, \k, \m, \M, \n, \V, \Y, and \z.
+
+	To anticipate objections: Why not throw only a warning?  Because
+	there isn't a warning category for supported but ambiguous
+	syntax (this behavior of AT&T troff dates back to the mid-1970s
+	but was not documented in the Troff User's Manual until 1992).
+	Why not throw the error outside of compatibility mode too?
+	Because outside of compatibility mode we (now) have an
+	unambiguous parse.
+
+	Background: The Graphic Systems C/A/T phototypesetter (the
+	original device target for AT&T troff) only supported a few
+	discrete point sizes in the range 6..36, so Ossanna
+	special-cased the parser to do what the user must have meant.
+	Kernighan warned of this in the 1992 revision of CSTR #54
+	{§2.3}, and more recently, McIlroy referred to it as a "living
+	fossil".

+
+	Accept any number of arguments for .Dd in the groff_mdoc(7)
+	macros.
+
+	* tmac/doc-common-u: The .Dd macro behaved in a weird way:
+	Without arguments, it printed the string "Epoch".
+	With one, two, four, or more arguments, it ignored all arguments
+	and used the current date instead.
+	Only for exactly three arguments, it printed the arguments.
+	None of this made sense.  Giving the date as "Epoch" is
+	absurd, and printing the current date is just misleading:
+	why should a document be considered up-to-date when the author
+	did not even bother to state the date of the last change?
+	Admittedly, the behaviour for 0 and 4 or more arguments
+	already appeared 4.3BSD-Reno, and the behaviour for 2 or 3
+	arguments in 4.4BSD.  But it was already wrong even in those
+	days: several manual pages in 4.4BSD gave .Dd a single, quoted
+	argument, e.g. .Dd "June 9, 1993": cap_mkdb(1), id(1), sed(1),
+	err(3), getcap(3), sysctl(3), amd(8), disklabel(8), and others.
+	Consequently, simply print all the arguments, no matter how
+	many there are.
+
+	This bug was found by Jonathan Gray <jsg@openbsd.org>

+
+2020-01-16  Ingo Schwarze  <schwarze@openbsd.org>
+
+	Repair .AT and .UC in the groff_man(7) macros.
+
+	* tmac/an-old.tmac: Setting user-defined strings in a macro that
+	will later be called indirectly from page location traps is
+	excessively complicated.  Besides, the implementation doesn't
+	work: when the trap is finally sprung, the defaults from the
+	an-init macro clobber what the author specified with .AT or .UC.
+	Instead, all that is needed is setting the strings for the
+	header before triggering the page break, such that they appear
+	right away, while setting the strings for the footer after the
+	page break, such that they don't appear on the previous page.
+
+	This bug was found by Jonathan Gray <jsg@openbsd.org> while he
+	looked at 4.xBSD manual pages.
+
+2020-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/groff_man.7.man (Document structure macros/.SH): Fix
+	errors in footer description.
+
+2020-01-12  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/tests/an-old_CS_register_on.sh: Tweak flags; all the
+	other tests in this group pass "-Tascii -P-cbou" instead of
+	"-Tutf8".  (This is so that output is easy to grep from a shell
+	script.)  Bring this test into line.  Does not regress anything.
+
+2019-12-30  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	Certain pdfmark destination names caused gropdf to fail.
+
+	* src/devices/gropdf/gropdf.pl: Look for pdfmark types, (i.e.
+	DEST, OUT, ANN), only preceding 'pdfmark' at end of line, not
+	anywhere else.
+
+2019-12-30  Ingo Schwarze  <schwarze@openbsd.org>
+
+	Correct output of sprintf("%%") in pic(1).
+
+	* src/preproc/pic/pic.ypp: Print "%" rather than "%%".
+
+	Bug reported by Doug McIlroy <doug at cs dot dartmouth dot edu>.
+	Patch using feedback from Larry McVoy <lm at mcvoy dot com>.
+
+2019-12-29  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	Update man page of gropdf to document \X calls.
+
+	* src/devices/gropdf/gropdf.1.man: The calls 'pagename' and
+	  'switchtopage' (used by mom to relocate TOC) are documented,
+	  together with their convenience commands '.pdfpagename' and
+	  '.pdfswitchtopage'.
+
+2019-12-29  Ingo Schwarze  <schwarze@openbsd.org>

+	strings.
+
+	* tmac/doc-common-u: Update.
+	* tmac/groff_mdoc.7.man: Synchronize.
+
+	Based on a patch from Guillem Jover <guillem@debian.org>
+	via Colin Watson <cjwatson@debian.org>, tweaked by me.
+	Fixes: https://bugs.debian.org/867123
+
+2019-09-22  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Use a vertical spacing of 1v between paragraphs in man page
+	examples.  This looks better (on typesetter devices like
+	PostScript and PDF) with the Courier font family also used in
+	examples.  Typewriter devices (like the terminal) already used
+	an inter-paragraph spacing of 1v.
+
+	* tmac/an-ext.tmac (EX): Save the value of the PD number
+	register (inter-paragraph distance), and set it to 1v.
+	(EE): Restore previous value of the PD register.
+
+2019-09-21  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	Changes to allow configure to check for URW fonts
+
+	* font/devpdf/util/BuildFoundries.pl: Call the program with
+	--dirURW with path provided to ./configure, and --check to do
+	a dry-run just checking if the fonts are available. (bug #56748)
+
+2019-09-21  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	Add new ghostscript font names (bug #56748)
+
+	* font/devpdf/Foundry.in: Add changed font names
+
+2019-09-21  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	Prevent gropdf executing arbitrary commands
+
+	* src/devices/gropdf/gropdf.pl: See bug #55557
+
+2019-09-15  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/an-old.tmac: Move test for definitions of CS and CT
+	registers to after man.local is sourced; this way we can both
+	respect any setting of those registers in that file (which is
+	intended for customization by the site administrator) and ensure
+	that the registers are defined when dereferenced later.
+
+2019-09-15  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* **/*.man: Put section headings in title case.
+
+2019-09-13  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/roff/troff/input.cpp: Lift invariant out of loop.
+
+2019-09-11  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/preproc/refer/refer.1.man: Add mention of man and mm
+	packages as supporting the "refer" preprocessor (GNU mm grew
+	this support back in groff 1.22.1).
+
+2019-09-10  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Mark expected-to-fail test as XFAIL.
+
+	Automake supports XFAIL and XPASS, so actually use the
+	infrastructure as intended.
+
+	* Makefile.am: Declare XFAIL_TESTS variable.
+	* src/roff/groff/groff.am (groff_XFAIL_TESTS): Add
+	string_case_xform_unicode_escape.sh.
+	* src/roff/groff/tests/string_case_xform_unicode_escape.sh: Set
+	the expected output to what it would be if string case
+	transforms worked on groff Unicode escapes.
+
+2019-09-10  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Retire '@G@' build system macro.
+
+	It existed only for forcibly-capitalized man page titles; it was
+	the uppercase-transformed counterpart of @g@.
+
+	* Makefile.am: Delete sed transformation of @G@.
+	* src/preproc/tbl/tbl.1.man: Replace '@G@EQN' in section heading
+	with '@g@eqn'.
+
+2019-09-10  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* **/*.man: Downcase man page titles, except for glilypond and
+	roff2*, which did not require it.
+
+	Here's a sed script for the aid of those who have a corpus of
+	man pages to migrate.
+
+		# Downcase man page titles.
+		#
+		# Use the first line to skip any .TH lines that require
+		# special handling, perhaps because the name of the
+		# command gets externally macro-expanded.  In groff, the
+		# "roff2.1.man" page is an example.
+		#
+		# This script operates _only_ on .TH lines.
+		#
+		# usage: sed -i -f this_script.sed your_man_page.1 ...
+		/@ROFF2MODE@/b
+		/^\.\s*TH/{
+		h
+		s/^\.\s*TH \+\([^ ]\+\) .*/\1/
+		y/ABCDEFGHIJKLMNOPQRSTUVWXYZ/abcdefghijklmnopqrstuvwxyz/
+		G

+		}
+
+2019-09-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	The an (man) macro package supports new CS and CT number
+	registers to control rendering of man page section headings and
+	titles, respectively, in full capitals.  These default off (with
+	no visible effect on pages which already fully capitalize these
+	strings in man page sources).  The rationale is to encourage man
+	page authors to preserve case distinction information in (or
+	restore it to) their titles and section headings, while giving
+	users (including system administrators, distributors,
+	integrators, and maintainers of man(1) implementations) a way to
+	view the rendered page elements in full capitals if desired.
+
+	* tmac/an-old.tmac (TH/an-init): If number register CT is
+	defined and nonzero, call .stringup on \*[an-title].
+	(SH): Store macro argument list to \*[an-section-heading].  If
+	number register CS is defined and nonzero, call .stringup on it.
+	* tmac/groff_man.7.man (OPTIONS): Document the CS and CT number
+	registers.
+	* tmac/tests/an-old_CS_register_off.sh:
+	* tmac/tests/an-old_CS_register_on.sh:
+	* tmac/tests/an-old_CS_register_unspecified.sh:
+	* tmac/tests/an-old_CT_register_off.sh:
+	* tmac/tests/an-old_CT_register_on.sh:
+	* tmac/tests/an-old_CT_register_unspecified.sh: Add tests.
+	* tmac/tmac.am (tmac_TESTS): Run tests.
+
+2019-09-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Add regression test to check behavior of case transformation
+	request on a string containing a Unicode character escape.
+	Right now, this is not supported, so it is an XFAIL test in the
+	parlance of DejaGNU/POSIX 1003.3.
+
+	* src/roff/groff/tests/string_case_xform_unicode_escape.sh: New
+	test.
+	* src/roff/groff/groff.am (groff_TESTS): Run test.
+
+2019-09-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Implement .stringdown and .stringup requests.
+
+	* src/roff/troff/input.cpp: Add .stringdown and .stringup
+	requests.
+	* doc/groff.texi: Document them, including example.
+	* man/groff_diff.7.man: Same.
+	* man/groff.7.man: Document them briefly.
+
+2019-09-09  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Regression-test string case transform feature.
+
+	* src/roff/groff/tests/string_case_xform_errors.sh: New test.
+	* src/roff/groff/tests/string_case_xform_requests.sh: New test.
+	* src/roff/groff/groff.am (groff_TESTS): Run tests.
+
+2019-06-30  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/devices/grotty/grotty.1.man (Options/-i): Note support of
+	recent versions of xterm for italic (oblique) styles.
+
+	Fixes part of <https://savannah.gnu.org/bugs/?55278>.
+
+2019-06-28  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	devlatin1: Map \(oq to ' on output.
+
+	* font/devlatin1/R.proto: Render the output glyph \[oq]
+	{opening quote} as 0x27 (apostrophe) instead of 0x60 (grave
+	accent).  A grave accent is just flat wrong for the Latin-1
+	character set, a.k.a. ISO 8859-1.  The defining document ECMA-94
+	{June 1986} is freely available for perusal.  The ECMA-94 Latin
+	character sets do not define any glyphs for directional
+	{"typographer's"} quotation marks, but the apostrophe is
+	depicted as a neutral (vertical) glyph, whereas the grave accent
+	0x60 and acute accent 0xB4 are mirror-symmetric diacritical
+	marks.
+
+	Note that this change has no effect on _input_ conventions for
+	roff source documents.  You can still get directional single
+	quotes on UTF-8, PostScript, PDF, and other output devices
+	supporting them by typing sequences like `this' in the input
+	{character remapping with ".char" requests and similar
+	notwithstanding}.
+
+	Patch and idea from Ingo Schwarze, who originally proposed it
+	for ASCII as well, and included Latin-1 for parallelism.
+	The groff developers could reach no consensus about the wisdom
+	of such a change for ASCII (which was designed to support
+	ambiguity for some code points, requiring the development of
+	supplementary interpretation conventions between parties).
+	ECMA-94/ISO-8859 is more strongly prescriptive.
+
+	See https://savannah.gnu.org/bugs/?55616 and the groff mailing
+	list archives for 31 January to 23 February 2019 at
+	https://lists.gnu.org/archive/html/groff for lengthy discussion.
+
+	* src/roff/groff/tests/on-latin1-device-oq-is-0x27.sh: Check for
+	correct output glyph.
+
+	* src/roff/groff/groff.am: Add test.
+
+2019-06-28  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/unicode.tmac: Save and restore compatibility mode since
+	the script uses a GNU extension (.char).
+
+2019-06-27  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	libdriver: Fix SEGV (Savannah #56555).
+
+	* src/libs/libdriver/printer.cpp: Check result of
+	set_char_and_width() for error condition before relying on it.
+
+	* src/roff/groff/tests/regression-56555.sh: Provoke segfault
+	with five bytes of input using transparent line indicator.
+
+	* src/roff/groff/groff.am: Add test.
+
+	Fixes <https://savannah.gnu.org/bugs/?55278>.
+
+2019-01-12  Ingo Schwarze  <schwarze@openbsd.org>
+
+	Correctly handle groff_mdoc(7) .Lk arguments starting with a
+	dot.
+
+	* tmac/doc.tmac-u: Each argument to the .Lk macro is printed
+	on its own roff input line.  If it happens to start with a dot
+	or apostroph, it was misinterpreted as a request or macro.
+	Force it to be treated as text by adding "\&" in front of it.
+
+2018-12-31  Ingo Schwarze  <schwarze@openbsd.org>
+
+	* man/groff_diff.7.man: remove two stray .RE macros

+
+	* src/preproc/grn/grn.man: Commenting out the -s option -- the
+	corresponding code doesn't work (yet).
+
+	* doc/groff.texinfo: Further checking/updating.  Adding more index
+	entries.
+
+2000-02-23  Werner LEMBERG  <wl@gnu.org>
+

+
+2000-02-11  Werner LEMBERG  <wl@gnu.org>
+

+
+2000-02-09  Werner LEMBERG  <wl@gnu.org>
+
+	* src/roff/groff/groff.man: Added an example.
+
+2000-02-06  Werner LEMBERG  <wl@gnu.org>
+
+	I've considerably modified the directory structure of the
+	distribution to get a more vertical layout.  For example, the number
+	of top level directories has been reduced from 42 to 6.
+
+	As a consequence, many changes, especially to the makefiles, were
+	necessary:
+
+	* The makefile variables `top_builddir' and `top_srcdir' have been
+	introduced.  Virtually all relative paths have been replaced with
+	absolute ones using these two variables.
+
+	* Dependencies (in the files `Makefile.dep') are no longer part of
+	the distribution.  Instead, they are created during a `make install'
+	in the build directory.
+
+	* aclocal.m4 (GROFF_SRCDIR, GROFF_BUILDDIR): Two new functions to
+	make `top_srcdir' and `top_builddir' absolute.
+
+	Some other changes:
+
+	* Man pages now depend on the files `VERSION' and `REVISION'.
+
+	* The added shell script `mkinstalldirs' will replace `mkdir' in
+	almost all cases.
+
+	* VERSION: Version number increased to 1.16.
+
+2000-02-04  Werner LEMBERG  <wl@gnu.org>
+
+	* grops/psrm.cc (read_one_of): Fixed pointer incrementation.
+
+	* Makefile.in: Removed $(tmac_m) since it is no longer needed
+	(after an update of the mm stuff).
+
+	* troff/Makefile.sub (majorminor.cc): Fix dependencies.
+
+2000-02-03  Werner LEMBERG  <wl@gnu.org>
+
+	The .psbb request will now also accept Mac PS images (i.e. using LF
+	as the EOL character).
+
+	* troff/input.cc (ps_get_line): New function, taken from psrm.cc
+	(with slight modifications).
+	* troff/input.cc (do_ps_file): Use it.
+
+	* test-groff: Add grohtml and grolj4 output devices to PATH.
+
+2000-01-30  Werner LEMBERG  <wl@gnu.org>
+
+	* NEWS, MORE.STUFF: Updated.
+
+2000-01-30  Cary D. Renzema  <caryr@dollar.mxim.com>
+
+	Add the `srand' command to pic.
+
+	* pic/lex.cc, pic/pic.y: Implement it.
+	* pic/pic.man: Document it.
+	* pic/pic.cc, pic/pic.tab.h: Regenerated (with yacc).
+
+2000-01-30  Werner LEMBERG  <wl@gnu.org>
+
+	Add a new request `.psbb'.  This does exactly what the external
+	program psbb did.  It scans a PostScript image file for a
+	%%BoundingBox comment and extracts the bounding box values (in
+	PostScript units) which	are then stored in the four new (read-only)
+	number registers `llx', `lly', `urx', and `ury'.
+
+	This will allow the usage of the .PSPIC macro without worrying
+	about unsafe behaviour of groff, i.e., it will work without the
+	`-U' switch of groff.
+
+	* troff/input.cc: Implement it.
+	* tmac/tmac.pspic: Use it.
+	* troff/troff.man, grops/grops.man, NEWS: Document it.
+	* psbb/*, Makefile.in: Remove it since it is no longer needed.
+
+	This is bloody C code simply adapted from psbb.c!  Any improvements
+	welcome.
+
+2000-01-29  Werner LEMBERG  <wl@gnu.org>
+
+	* man/groff_font.man: Minor clarifications.
+
+	* NEWS: Updated.
+
+2000-01-28  Werner LEMBERG  <wl@gnu.org>
+
+	* afmtodit/afmtodit.pl: Use new `--' comment delimiter.

+2000-01-28  Gaius Mulley  <gaius@glam.ac.uk>
+
+	* man/groff_font.man: Brought up to date regarding tcommand

+
+2000-01-28  Werner LEMBERG  <wl@gnu.org>
+

+2000-01-27  Gaius Mulley  <gaius@glam.ac.uk>
+
+	Completed the pass_filenames implementation in troff.
+
+	* libdriver/input.cc: Will read the new `F' tcommand.
+	* troff/node.cc, troff/node.h: Will issue the new `F' tcommand.
+	* troff/input.cc: Use it.
+
+2000-01-26  Werner LEMBERG  <wl@gnu.org>
+
+	* troff/env.cc (set_font): Fix the behaviour of \fP.  The previous
+	font will now be updated even if an invalid font is selected.
+
+2000-01-24  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/homepage.ms: Updated for new tmac.arkup.
+
+	* tmac/tmac.html: Disable line breaks after hyphen-like characters.
+
+	* tmac/tmac.arkup: Cleanup.
+
+	Added `\&' to .HTML macro to `leave vertical mode', so to say.
+
+	Removed obsolete .LINK macro completely.
+
+	The macros .URL, .FTP, and .MAILTO now accept a third argument which
+	will be immediately appended to the second argument (to be used with
+	punctuation, for example).
+
+	Disabled .CDFTP macro temporarily for security reasons.
+
+	* tmac/groff_markup.man: Complete revision for latest changes in
+	tmac.arkup -- note that it does not yet format correctly with

+
+	* tmac/groff_tmac.man: Fix typo.
+
+2001-02-16  Werner LEMBERG  <wl@gnu.org>
+
+	Fixing a bug which prevented proper end-of-sentence recognition
+	between an `unformatted' box and the following text.  As a
+	consequence, vertical line distances are no longer preserved in
+	boxes after a call to `.unformat' -- because boxes aren't
+	line-oriented (contrary to diversions), this doesn't make sense
+	anyway.
+
+	* src/roff/troff/node.cc (*node::set_unformat_flag): Add return
+	value.
+	(vertical_size_node::set_unformat_flag): New method.

+	documentation of `asciify' and `unformat' requests.
+
+2001-02-13  Werner LEMBERG  <wl@gnu.org>
+
+	Redesigned the `unformat' request.  It is no longer connected with
+	`asciify' but rather uses new `reread()' methods if the `unformat'
+	flag is set.  Additionally, the handling of space characters after
+	unformatting has been fixed so that they retain their width.
+
+	* src/roff/troff/node.h (width_list): New structure to store
+	original widths of spaces.
+	(node): Added `unformat' member.
+	Replaced `num_spaces' variable with `orig_width' list.
+	* src/roff/troff/node.cc (*node::asciify,
+	asciify_reverse_node_list): Removed `unformat_only' flag and related
+	code.
+	(word_space_node::asciify, word_space_node::word_space_node): Use
+	`orig_width'.
+	(word_space_node::~word_space_node): New destructor.
+	(word_space_node::copy): Updated to handle `orig_width'.
+	(hmotion_node::copy, unbreakable_space_node::copy): Updated.
+	(*node::merge_space): Update `orig_width' list if necessary.
+	(*node::set_unformat_flag): New methods to set the `unformat' flag.
+	* src/roff/troff/enc.cc (environment::space_newline): Use
+	`width_list'.
+	(environment::space): Added method to handle space width and
+	sentence space width as parameters.  Use `width_list'.
+	(environment::make_tab_node): Updated.
+	* src/roff/troff/env.h: Updated.
+	* src/roff/troff/input.cc (word_space_node::reread,
+	unbreakable_space_node::reread, hmotion_node::reread): New methods
+	to handle nodes specially if `unformat' flag is set.
+	(do_asciify_macro): Renamed back to ...
+	(asciify_macro): This.
+	(unformat_macro): New implementation to simply set the `unformat'
+	flag.
+
+	* MORE.STUFF: Added more info about deroff.
+
+2001-02-08  Werner LEMBERG  <wl@gnu.org>
+
+	* src/roff/troff/node.h (unbreakable_space_node, hmotion_node,
+	space_char_hmotion_node, overstrike_node): Add `get_hyphen_list()'
+	and `add_self()' methods to avoid hyphenation.  For example, the
+	hyphen list for `foo\0\0bar' was `foobar', causing insertion of a
+	soft hyphen after `foo'.  Now the hyphen list is correctly
+	`foo<ignore><ignore>bar'.
+
+2001-02-05  Yoshiteru Kageyama  <yt-kage@cb3.so-net.ne.jp>
+
+	* tmac/groff_tmac.man: Fix `BIR' macro.
+
+2001-02-04  Werner LEMBERG  <wl@gnu.org>
+
+	A new escape sequence `\:', inserting a zero-width break point.

+	Implement it.
+	* src/roff/troff/node.h (node): Add `is_escape_colon()' virtual
+	method.
+	(space_node): Add `was_escape_colon' member.  Add `is_escape_colon()'
+	and `asciify()' methods.
+	* src/roff/troff/node.cc (space_node::space_node): Updated.
+	(space_node::asciify): Handle `was_escape_colon'.
+	* NEWS, src/roff/troff/troff.man, man/groff.man: Document it.
+
+	Handle `\~' similar to other comparable requests.
+
+	* src/roff/troff/input.cc (process_input_stack): Remove now obsolete
+	label.
+	(token::next): Move creation of an unbreakable_space_node to...
+	(token::add_to_node_list): Here.
+
+	Fix a bug which sometimes prevented hyphenation of words connected
+	with `\~' or `\ ' (and other escape sequences handled as
+	TOKEN_NODE).  This also fixes a hyphenation problem with boxes
+	(after a call to the `unformat' request).
+
+	* src/roff/troff/env.h (environment::possibly_break_line,
+	environment::hyphenate_line): Introducing `start_here' parameter.
+	* src/roff/troff/env.cc (environment::space_newline,
+	environment::space): Use it.
+	(environment::possibly_break_line, environment::hyphenate_line):
+	Implement it.
+	* src/roff/troff/input.cc (process_input_stack): Use it.
+	* src/roff/troff/node.h (unbreakable_space_node, hmotion_node,
+	space_char_hmotion_node, overstrike_node): Add
+	`get_hyphenation_type()' method.
+	* src/roff/troff/node.cc (break_char_node::asciify): Don't asciify
+	if `unformat_only' is active.
+
+2001-01-30  Werner LEMBERG  <wl@gnu.org>
+
+	Implemented new read-only number register `.linetabs' which
+	returns 1 if in line-tabs mode, 0 otherwise.
+
+	* src/roff/troff/env.h (environment): Add get_line_tabs() member.
+	* src/roff/troff/env.cc (get_line_tabs): New function.
+	(init_env_requests): Use it.
+	* NEWS, src/roff/troff/troff.man, man/groff.man: Document it.
+
+	* VERSION, REVISION: Changing to 1.17.0.
+
+2001-01-28  Werner LEMBERG  <wl@gnu.org>
+
+	Fixed a bug which prevented hyphenation of words which are finished
+	with `\)'.
+
+	* src/roff/troff/token.h (token): Add enum type
+	`TOKEN_TRANSPARENT_DUMMY' and method `transparent_dummy()'.
+	* src/roff/troff/input.cc (token::next, token::description,
+	get_line_arg, token::add_to_node_list, token::process): Use it.
+
+2001-01-27  Werner LEMBERG  <wl@gnu.org>

+	* src/roff/troff/div.cc (do_divert): Use it.

+
+2001-01-25  Werner LEMBERG  <wl@gnu.org>
+
+	Adding the `linetabs' request.  If set, tab distances are not
+	computed relative to the input line but relative to the output line.
+
+	* src/roff/troff/env.h (environment): New member `line_tabs'.
+	* src/roff/troff/env.cc (line_tabs_request): Implement request.
+	(environment::environment, environment::copy): Updated.
+	(environment::distance_to_next_tab): Use `line_tabs'.
+	(init_env_requests): Register request.
+	* src/roff/troff/troff.man, man/groff.man, NEWS: Document it.  Other
+	fixes.
+
+2001-01-24  Werner LEMBERG  <wl@gnu.org>
+
+	Introducing a new read-only register `.int' which is set to a
+	positive value if the last output line is interrupted (i.e., if it
+	contains `\c').
+
+	* src/roff/troff/env.cc (init_env_requests): Add it.
+	* NEWS, src/roff/troff/troff.man, man/groff.man: Document it.

+	`asciify' request.

+	* env.cc (environment::make_tab_node): Set it.
+	* node.cc (hmotion_node::copy, hmotion_node::asciify): Use it.
+
+	Added new request `unformat' which will, contrary to `asciify',
+	preserve font information after unformatting (i.e., only nodes
+	dealing with horizontal space are converted back to input
+	characters).
+
+	* input.cc (asciify_macro): Renamed to ...
+	(do_asciify_macro): this, having a new parameter `unformat_only'.
+	(asciify_macro, unformat_macro): New; using do_asciify_macro.

+
+	First cut of the new html device driver.  Changes to pre-html and
+	the new grohtml are too numerous to be documented here.
+
+	Stuff related to `html' has been renamed to `html-old' and `html2'
+	stuff has been renamed to `html' (including directories).  The new
+	html device driver is therefore invoked as `-Thtml'.
+
+	Added new `\O' escape to suppress output (needed by html driver).
+
+	Added functions and code to pass info about input-level commands
+	(`.in', `.fl', etc.) to html driver.
+
+	Three new functions (.html-begin, .html-end, and .html-image) for
+	better html handling: `html-begin' will execute the remaining line
+	if at the outermost nesting level, increasing an internal counter.
+	`html-end' does the same but decreases the internal counter.
+	`html_image' puts its arguments into a special node (suppress_node)
+	to define an image region.
+
+	The `output' request has been removed.
+
+	* tmac/html-tags.tmac: Removed.

+	
+2000-10-14  Werner LEMBERG  <wl@gnu.org>

+	src/preproc/html2/pre-html.cc, src/preproc/html2/pushbackbuffer.cc,
+	src/roff/groff/pipeline.c: Removing `#ifndef errno' to avoid
+	compilation errors with some compilers.  It seems that this code
+	is no longer necessary -- if yes, it is easy to add some #ifdef's
+	for that particular old-fashioned compiler.
+
+	* MORE.STUFF: Added info about Meta-tbl.
+
+	* doc/groff.texinfo: Added more info about `.if "..."..."'.
+
+2000-10-07  Werner LEMBERG  <wl@gnu.org>

+	the delimiters is a valid numeric expression, return the character
+	`1', and `0' otherwise.  This is an analogon to \A.
+
+	* src/roff/troff/input.cc (do_expr_test): Implement it.
+	(token::next): Use it.
+	* src/roff/troff/troff.man, NEWS, man/groff.man: Document it.
+
+	* tmac/tmac.trace: Made independent from escape character.
+
+2000-10-06  Werner LEMBERG  <wl@gnu.org>
+
+	Adding a new request .dei: define indirect.  The first and second
+	parameter of .dei are taken from string registers instead directly;
+	this very special request is needed to make tmac.trace independent
+	from the escape character (which might even be disabled).
+
+	* src/roff/troff/input.cc (do_define_macro): Implement it.
+	(define_macro_indirect): New function.
+	(init_input_requests): Use it.

+	Implement it.
+	(init_input_requests): Use it.
+
+	* src/roff/troff/troff.man, NEWS, man/groff.man: Updated.
+
+2000-09-22  Ricardo Soares Guimar�es  <ricardo@conectiva.com.br>

+	to grops, selecting a different prologue file (minor modifications
+	by WL).
+
+	* src/devices/grops/psrm.cc (resource_manager::output_prolog),
+	src/devices/grops/ps.cc (main): Implement it.
+	* src/devices/grops/grops.man, NEWS: Document it.

+	strings.h from the former to the latter.
+	* src/devices/grolbp/lpb.cc, src/include/lib.h: Move strncasecmp()
+	stuff from the former to the latter.
+
+2000-09-11  Werner LEMBERG  <wl@gnu.org>
+
+	Implementing two new requests .tm1 and .tmc: The former is similar
+	to .tm but can output leading spaces; its syntax is similar to
+	defining a string, i.e., a `"' can be used to mark the beginning of
+	the string to be written to stderr: `.tm1 " test'.  The latter is
+	similar to .tm1 but doesn't write out a final newline character.
+
+	* src/roff/troff/input.cc (terminal1, terminal_continue,
+	do_terminal): New functions.
+	(init_input_requests): Use them.
+	* src/roff/troff/troff.man, NEWS, man/groff.man: Updated.

+
+	* tmac/groff_mdoc.man: Fixing typo.
+
+2000-09-02  Werner LEMBERG  <wl@gnu.org>
+
+	Implementing a .nop request which does nothing.
+
+	* src/roff/troff/input.cc (nop_request): New function.
+	(init_input_requests): Use it.
+	* src/roff/troff/troff.man, NEWS, man/groff.man: Updated.
+
+2000-09-01  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/groff.texinfo: Added some comments.

+	* doc/groff.texinfo: Fix comment how to compile the DVI file.
+
+2000-08-25  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* font/devps/generate/Makefile (SHELL): Define explicitly to
+	"/bin/sh", for non-Unix platforms.
+	(extraclean): Use a more portable "" quoting instead of a
+	backslash (which doesn't work on DOS/Windows).
+	
+	* font/devlj4/generate/Makefile (extraclean): Ditto.
+
+	* font/devdvi/generate/Makefile (extraclean): Ditto.
+
+2000-08-25  Werner LEMBERG  <wl@gnu.org>
+
+	* NEWS, doc/groff.texinfo, tmac/groff_tmac.man, man/roff.man,

+
+	* test-groff: Updated.
+
+2000-08-24  Gaius Mulley  <gaius@glam.ac.uk>
+
+	Added the new troff command .output <arg> to suppress output (while
+	still obeying motion) and also the opminx, opminy, opmaxx, opmaxy
+	registers (for passing the output dimensions to the output device).
+
+	* src/roff/troff/div.cc (top_level_diversion::output): Use `width'
+	parameter.

+	real_output_file::really_off): New functions.
+	(real_output_file:public output_file): New variable `output_on'.
+	(real_output_file::begin_page, real_output_file::copy_file,
+	real_output_file::transparent_char, real_output_file::print_line):
+	Use it.
+	(real_output_file::print_line): Use check_output_limits.
+	* src/roff/troff/reg.h, src/roff/troff/request.h,

+	* src/devices/grolbp/lbp.cc: Same workaround for sinix as for AIX.
+
+2000-08-22  Werner LEMBERG  <wl@gnu.org>

+	groff-getopt.h.
+
+2000-08-18  Werner LEMBERG  <wl@gnu.org>
+
+	* configure.in: Don't provide an empty value for SH_SCRIPT_SED_CMD
+	since some non-GNU sed programs can't handle null regexps.

+
+2000-08-06  Paul Eggert  <eggert@twinsun.com>

+
+2002-10-07  Werner LEMBERG  <wl@gnu.org>
+
+	* tmac/doc-common (Ss): Add final `.ns' (similar to `.Sh') to
+	suppress additional whitespace after the header.
+
+	* tmac/doc-ditroff, tmac/doc-nroff (Am): New string to be in sync
+	with NetBSD.
+
+	* src/preproc/grn/grn.man, tmac/groff_mdoc.man, NEWS: Updated.
+
+2002-10-07  Ruslan Ermilov  <ru@FreeBSD.org>
+
+	* tmac/doc-common(doc-volume-operating-system-ateol): New flag.
+	(Dt): Use it to improve language localization (especially Russian
+	and French).

+
+2002-10-02  Werner LEMBERG  <wl@gnu.org>
+
+	Redesigning color support in troff.  Colors are no longer
+	represented as separate nodes but are now part of glyph nodes and
+	friends.  This fixes the current formatting misbehaviour due to the
+	changes introduced on 2002-09-20.  Some extra code is necessary for
+	proper grotty support: Without adding color variables to
+	space-related nodes, the background color would be changed too late.
+
+	* src/roff/troff/node.h, src/roff/troff/node.cc:
+	s/current_pagecolor/current_fill_color/.
+	s/current_glyphcolor/current_glyph_color/.

+	and `set_line_thickness, depending on the current font size.
+
+2002-09-21  Werner LEMBERG  <wl@gnu.org>
+
+	Some Debian patches.
+
+	* src/roff/groff/pipeline.h (MAX_COMMANDS): Increase to 12.

+	correctly.
+
+2002-09-17  Werner LEMBERG  <wl@gnu.org>

+
+	* src/preproc/eqn/box.cc (output_string): Don't use \\*[...].
+	* src/preproc/eqn/main.cc (do_file, inline_equation): Call

+	register now already contains proper switches from and to
+	compatibility mode.
+
+	* man/groff_char.man: Add Euro symbol.
+	* man/groff_diff.man: Improve documentation of `.am1' and `.as1'.

+
+2002-02-03  Werner LEMBERG  <wl@gnu.org>

+	are equivalent to `ds' and `as' with the difference that
+	compatibility mode is saved on entry, switched off during string
+	expansion, and restored on exit.  The latter is the pendant to `dei'
+	for `am'.
+
+	(do_define_string): Use `define_mode' and `calling mode'.
+	Insert COMPATIBLE_SAVE and COMPATIBLE_RESTORE at the beginning and

+
+	* src/preproc/eqn/box.cc (box::top_level, box::extra_space): Use
+	`as1' for assigning LINE_STRING (this is `10' usually).  Sun's
+	mm macro package accesses this string register directly.
+	* src/preproc/eqn/main.cc (inline_equation): Use `as1'.
+
+	* tmac/trace.tmac: Trace calls to `am' also.  Make it work in
+	compatibility mode.

+	out the unused `{' and `}' commands.  Undefined by default.
+	(IntArray): Make `data' private.
+	(IntArray::operator[], IntArray::get_data, IntArray::len): Use these
+	new methods instead.
+	(skip_line_D, skip_to_end_of_line): New functions.
+	(get_D_fixed_args): Use `skip_line_D'.
+	Changed to handle dummy odd arguments by ...
+	(get_D_fixed_args_odd_dummy): This new function.

+	  Adapt programs to the new libdriver/input.cc.
+
+	  Color spaces are no longer converted to RGB but transferred as-is
+	  in the troff intermediate output format.

+	  Handle default color gracefully.  troff now supports a `default'
+	  color (which can't be changed).
+

+
+	Implementing color support in troff, pic, grops, and grohtml.  These
+	changes are based on a major patch provided by Gaius Mulley
+	<gaius@glam.ac.uk>.
+
+	New request: `defcolor', supporting rgb, cmy, cmyk, and gray
+	definitions with both hex values and fractions.
+
+	New escapes: \m and \M for drawing and background color,
+	respectively.  This corresponds to the troff output commands `m'
+	and `DF'.
+
+	groff and troff accept command line switch `-c' to disable color
+	output (which is automatically disabled in compatibility mode).
+
+	New scaling indicator `f' for fractions (1f = 65536u).
+
+	New conditional operator `m' to test for defined colors with `if'
+	and `ie'.
+
+	New keywords `color' (or `colour', `colored', `coloured'), `outline'
+	(or `outlined'), and `shaded' added to pic.
+
+	* src/include/color.h: New file.
+	* src/include/driver.h: Include it.

+
+2005-06-22  Werner LEMBERG  <wl@gnu.org>
+
+	Another round in fixing getopt problems.  Hopefully the last one!
+	This time we use the getopt stuff from gnulib and define a prefix
+	unconditionally so that there are no collisions with any other
+	getopt implementations.  This is a slight waste of space in case
+	we already use a GNU getopt implementation, but on
+	the other hand it really simplifies life.
+
+	* src/include/getopt.h: Use gnulib version.
+
+	* src/include/getopt_int.h: Use gnulib version.
+
+	* src/include/groff-getopt.h: Removed.  Obsolete now.
+
+	* src/include/lib.h: Regarding getopt, don't handle any platform
+	specially; just include getopt.h.
+	(__GETOPT_PREFIX): Define (before getopt.h).
+
+	* src/include/Makefile.sub (HDRS): Updated.
+
+	* src/libs/libgroff/getopt1.c, src/libs/libgroff/getopt.c: Use
+	gnulib version.
+
+	* src/libs/libgroff/Makefile.sub (EXTRA_CFLAGS): Set
+	__GETOPT_PREFIX.
+
+	* src/utils/pfbtops/pfbtops.c, src/utils/xtotroff/xtotroff.c
+	(__GETOPT_PREFIX): Define (before getopt.h).
+
+2005-06-21  Werner LEMBERG  <wl@gnu.org>
+
+	* src/include/lib.h: Provide a fix for Mac OS X to not include
+	groff-getopt.h.
+
+2005-06-20  Denis M. Wilson  <dmw@oxytropis.plus.com>
+
+	* font/devps/prologue.ps (EP): Don't use `bind'.  Reason: Using
+	`bind' to define a procedure which contains `showpage' means that an
+	invocation of `showpage' may execute wrongly (the exact effect
+	depending on the interpreter).  Not usually a problem except under
+	transformations, such as combining pages.
+	(PEND): Don't call `clear'.  Reason: Using `clear' in the definition
+	of /PEND means that stack underflow will occur if the stack is
+	deliberately non-empty before document inclusion.  If included
+	files are found to be generally badly behaved, we could replace the
+	`clear' with `mark' in /PBEGIN and `cleartomark' in /PEND (I've
+	never found this necessary).
+
+2005-06-20  J�rgen Grahn  <jgrahn@algonet.se>
+
+	* src/preproc/soelim/soelim.cpp (do_file): Append trailing zero
+	earlier to get correct error message.
+
+2005-06-16  Bernd Warken <groff-bernd.warken-72@web.de>
+	* src/roff/nroff/nroff.sh: Add support for iso-8859-15.
+
+2005-06-15  Werner LEMBERG  <wl@gnu.org>
+
+	Another try to update getopt files.  This time we add a dummy
+	gettext.h file to satisfy the dependency.
+
+	* src/include/getopt.h, src/libs/libgroff/getopt.c,
+	src/libs/libgroff/getopt1.c: Updated from GNU libc CVS.
+
+	* src/include/getopt_int.h: New file (from GNU libc CVS).
+
+	* src/include/gettext.h: Dummy file which just defines a gettext()
+	macro.
+
+	* src/include/groff-getopt.h: Updated.
+
+	* src/include/Makefile.sub (HDRS): Add getopt_int.h and gettext.h.
+
+
+	* src/libs/libdriver/input.cpp (IntArray): Remove superfluous
+	`const' keywords in return value.

+	(pushBackBuffer::skipToNewline): Remove redundant variable `ch'.
+
+	* src/preproc/tbl/main.cpp (process_table): Remove redundant
+	variable `c'.
+
+
+	Fix more friend name injection problems since modern C++ compilers
+	fail otherwise.  We simply provide (global) declarations for all
+	functions declared as friends.  This is not really necessary but
+	doesn't harm.
+
+	* src/preproc/eqn/lex.cpp: Provide declarations for get_char,
+	peek_char, and get_location.
+
+	* src/preproc/refer/ref.h: Provide declarations for
+	compare_reference, same_reference, same_year, same_date,

+	* src/roff/troff/div.h: Provide declarations for do_divert and
+	page_offset.
+
+	* src/roff/troff/env.h: Provide declarations for title_length,
+	space_size, fill, no_fill, adjust, no_adjust, center, right_justify,
+	vertical_spacing, post_vertical_spacing, line_spacing, line_length,
+	indent, temporary_indent, do_underline, do_input_trap, set_tabs,
+	margin_character, no_number, number_lines, leader_character,
+	tab_character, hyphenate_request, no_hyphenate,
+	hyphen_line_max_request, hyphenation_space_request,
+	hyphenation_margin_request, line_width, tabs_save, tabs_restore,
+	line_tabs_request, widow_control_request, and do_divert.
+
+	* src/roff/troff/input.cpp: Provide declaration for chop_macro.
+
+	* src/roff/troff/node.cpp: Provide declarations for class
+	tfont_spec.

+
+	These patches modify the indentation implementation to use `<p
+	style=margin-left: n%>'.  Many thanks to Peter and Larry for
+	suggesting this solution.  Grohtml only uses tables for `.IP' and
+	related tags when the first operand has a short width.
+
+	Similarly, they modify all vertical space code.  By default, grohtml
+	sets up a style sheet which uses no vertical space between `table',
+	`pre', and `p' tags.  It forces spaces when it needs them using
+	`style="margin-top: 1em"'.

+	Registers): Document changes from 2004-09-19.
+
+2004-09-23  Werner LEMBERG  <wl@gnu.org>

+
+2004-09-19  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	This change implements the following features:
+
+	PORPHANS
+	  New numeric register: Defines number of lines following LP, PP,
+	  QP, IP or XP, which must be kept together, before any automatic
+	  page break.  If insufficient space remains on the current page, a
+	  page break is forced before the new paragraph begins.
+
+	HORPHANS
+	  New numeric register: Sets number of lines of following paragraph
+	  which must be kept with a heading, defined by NH or SH, before any
+	  automatic page break.  If insufficient space remains on the
+	  current page, a page break is forced before the heading.
+
+	GROWPS
+	  (Thanks to Joerg van den Hoff, for this idea).
+
+	  New numeric register: Sets the first level of heading (set with
+	  NH), which will keep the same point size as body text; e.g. if
+	  GROWPS is set to 3, .NH 3, .NH 4, ... will produce headings at the
+	  point size specified by \n[PS], but .NH 2 and .NH 1 will have
+	  progressively larger point sizes, determined by \n[PSINCR] (see
+	  below).
+
+	PSINCR
+	  New numeric register: Sets the point size increment for each level
+	  of heading, (set with NH), below the threshold level set by
+	  GROWPS; e.g. if \n[PS] = 10, \n[GROWPS] = 3 and \n[PSINCR] = 2.0p,
+	  then .NH 1 will produce 14pt headings, .NH 2 will produce 12pt,
+	  and all other levels will remain at 10pt, (because \n[PS] = 10).
+
+	SH
+	  Existing macro now accepts a numeric argument, to make heading
+	  size match that of NH with same argument value, when the
+	  GROWPS/PSINCR feature is enabled.
+
+	SN-DOT
+	  New string, set by NH macro, replaces the existing (undocumented)
+	  use of SN, to represent the assigned section number.
+
+	SN-NO-DOT
+	  New string, set by NH macro, represents the assigned section
+	  number, but omits the terminal period (periods at intermediate
+	  levels are retained).
+
+	SN
+	  String set by NH macro, originally undocumented, now implemented
+	  as an alias for SN-DOT (which reproduces original behaviour).
+
+	* tmac/s.tmac (PORPHANS): New register.
+	(par*start): Use it.
+	(HORPHANS, GROWPS, PSINCR): New registers.
+	(SH-NO-TAG, @SH): Use them.

+	is extremely time-consuming to produce, given that HP's metric
+	files are very rudimentary.

+
+2008-09-29  Werner LEMBERG  <wl@gnu.org>

+	  .cp 1
+	  .do xx
+
+	prints 1 instead of 0.

+2008-05-02  Larry Jones  <lawrence.jones@siemens.com>
+
+	* contrib/chem/Makefile.sub (README, examples/README): In makefiles,
+	the `$<' macro is only guaranteed to be defined in inference rules,

+	defined for both kinds of rules) is a suitable replacement.

+	Add better support for `.TAG #<label>' in non-HTML documents: In

+	In case of a backwards reference use the page number instead.  The
+	reference gets stored in a string `TAG_<label>' and can be
+	overridden while calling `.TAG' with its new optional argument --
+	this is useful for a second-pass system which resolves forward
+	references.
+
+	* tmac/www.tmac (www:url_check_tag): New function.

+
+	* man/groff_out.man: First step in macro simplification; eliminate

+
+
+	Add support for MathML output to eqn.
+
+	The strategy used is very simple and relies on the fact that the box
+	models of eqn and Presentation MathML differ in only trivial ways.
+	It leaves the grammar and existing internal object structures
+	unchanged.  A new global, `output_format', is defined as an
+	enumerated type with values {troff, mathml}.  Most of the functions
+	and methods that emit actual output acquire a top-level conditional,
+	dispatching on this global, which has one arm for troff mode and one
+	for MathML mode.  In most cases the MathML arm is drastically
+	simpler.
+
+	(This strategy could be easily generalized to support other output
+	formats.  TeX is a possibility that leaps to mind.)
+
+	The only even moderately tricky changes are in the lexer.  Some of
+	the predefined macros used constructs like `up', `down', `fwd',
+	`back', and `vcenter' that have no equivalents in MathML.  I
+	attacked this problem in these ways:
+
+	1. I eliminated three uses of `back' to compose characters in favor
+	   of using equivalent groff specials `\(<<', `\(>>', and `\(<>'
+	   that did not exist when these macros were written.  (This will be
+	   a quality improvement for troff users.)
+
+	2. I eliminated one use of `vcenter' by using \\(md.  (Likewise...)
+
+	3. I then split the table of pre-definitions in three; one large
+	   common table and two small troff-specific and MathML-specific
+	   tables.  Use of troff-only operations (up, down, back, fwd,
+	   vcenter) is now confined to the former.  The latter now uses
+	   `size big' and drops out the explicit positioning operations,
+	   counting on MathML processors to do them.
+
+	POTENTIAL TROUBLE SPOTS:
+
+	Here are notes for reviewers on places I'm not 100% sure I've done
+	the right thing:
+
+	* In the process of preparing the troff table, I translated three
+	  definitions (dot_def, dotdot_def, and utilde def) that previously
+	  used explicit \v escapes to use `up' and `down' instead.  I
+	  modeled the new definitions on the way `vec' and `dyad' work, but
+	  it's possible I got something subtle wrong.
+
+	* I'm not certain the MathML implementation of font_box::output() is
+	  right, because I don't quite get what the switcheroo between
+	  `current_roman_font' and `old_roman_font' is supposed to
+	  accomplish.  It does seem to generare good MathML, though.
+
+	Finally, I made one purely cosmetic change in `text.cpp'; I replaced
+	with an enum some magic numbers for spacing types that I thought
+	were too ugly to live.
+
+	REMAINING ISSUES:
+
+	The entirety of eqn is translated when `-TMathML' is specified,
+	with the following exceptions...
+
+	Limitations that cannot be fixed include non-support for special,
+	up/down/fwd/back, and vcenter.
+
+	Limitations that might be fixable include non-support for mark and
+	lineup.  I will investigate further, but if these can be implemented
+	at all it's going to be in a very complicated and nasty way.
+
+	The way character boxes are output means that each digit of a
+	multi-digit number gets its own <mn></mn> tag pair in the MathHTML.
+	While this is not technically wrong for Presentation MathML, it is
+	ugly and inefficient.  Fixing this will require implementing a
+	little state machine in the `text.cpp' output method.

+	(do_file): Emit error message in case of unsupported encoding.
+
+2005-12-31  Werner LEMBERG  <wl@gnu.org>

+2005-12-02  Werner LEMBERG  <wl@gnu.org>
+
+	* src/devices/grops/ps.cpp (ps_printer::get_subfont): Use correct

+Version 1.21 released
+=====================
+
+	* NEWS, REVISION, VERSION, doc/groff.texinfo, doc/webpage.ms:
+	Updated.
+	* aclocal.m4, configure: Regenerated.
+
+2010-12-31  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/webpage.ms: Updated.
+
+2010-12-31  Werner LEMBERG  <wl@gnu.org>
+
+	* configure: Regenerate with autoconf 2.67.
+
+2010-12-31  Werner LEMBERG  <wl@gnu.org>
+
+	Update various scripts.
+
+	* config.guess, config.sub: Update from `config' repository.
+	* install-sh, mkinstalldirs: Update from `gnulib' repository.
+
+2010-12-31  Werner LEMBERG  <wl@gnu.org>
+
+	Update texinfo.tex.
+
+	* doc/texinfo.tex: Update from `texinfo' repository.
+
+2010-12-30  Werner LEMBERG  <wl@gnu.org>
+
+	Call texi2dvi with correct makeinfo binary.
+
+	* doc/Makefile.in (.texinfo.dvi, .texinfo.pdf): Use $(MAKEINFO).
+
+2010-12-30  Werner LEMBERG  <wl@gnu.org>
+
+	Documentation updates.
+
+	* NEWS, PROBLEMS, MANIFEST: Update.
+
+2010-12-26  Werner LEMBERG  <wl@gnu.org>
+
+	Speed up troff.
+
+	* src/include/ptable.h (PTABLE): Make hash tables much more sparse
+	by changing the ratio `FULL_NUM/FULL_DEN' from 2/3 to 1/4.  This
+	increases the allocated memory by about 200kByte (which is nothing
+	today) but assures that there aren't extremely long searches for a
+	free hash slot in case that the hash function doesn't return a free
+	one.  Due to the nature of the entries in uniuni.cpp, the used hash
+	function in ptable.cpp is not optimal, but using a sparse array
+	compensates this.
+
+2010-12-20  Werner LEMBERG  <wl@gnu.org>
+
+	Replace patch from 2010-12-18 with a much faster implementation.
+
+	* src/roff/troff/node.h (node): Add virtual function
+	`get_break_code'.
+
+	* src/roff/troff/node.cpp (inter_char_space_node): Remove class
+	completely.
+	(glyph_node::merge_glyph_node): Restore previous version.
+
+	(break_char_node): Add `prev_break_code' field and update
+	constructors.
+	(node::get_break_code, break_char_node::get_break_code): Implement.
+
+	(node::add_char): Pass remaining cflags values.
+
+	(break_char_node::add_self): Use the logic of the now deleted
+	`inter_char_space_node::add_self' function to insert a space node if
+	necessary.
+
+2010-12-20  Daiki Ueno  <ueno@unixuser.org>
+
+	A new try to not changing srcdir if building in separate builddir.
+
+	Makefile.in ($GNULIBDIRS): Disable calls to autoconf and friends.
+
+2010-12-20  Werner LEMBERG  <wl@gnu.org>
+
+	Speed up access to cflags values.
+
+	We now recompute the cflags values for all charinfo objects if
+	`.class' has been called.
+
+	* src/roff/troff/charinfo.h: Add external references to `class_flag'
+	and `get_flags'.
+	(charinfo): `get_flags' no longer has a return value.
+	(charinfo::overlaps_horizontally, charinfo::overlaps_vertically,
+	charinfo::can_break_before, charinfo::can_break_after,
+	charinfo::can_break_after, charinfo::ends_sentence,
+	charinfo::transparent,, charinfo:ignore_hcodes,
+	charinfo::prohibit_break_before, charinfo::prohibit_break_after,
+	charinfo::inter_char_space): Call global `get_flags' only if
+	necessary.
+	(charinfo::add_to_class): Set `class_flag'.
+
+	* src/roff/troff/input.cpp (class_flag): New global flag.
+	(charinfo::charinfo): Call `get_flags' member function.
+	(get_flags): New global function which iterates over all entries in
+	the charinfo dictionary.
+	(charinfo::get_flags): Set `flags' directly.
+
+2010-12-19  Werner LEMBERG  <wl@gnu.org>
+
+	Protect `.class' against cyclic nesting.
+
+	* src/roff/troff/charinfo.h (charinfo::contains): Add optional
+	boolean argument.
+	* src/roff/troff/input.cpp (define_class, charinfo::contains): Check
+	for cyclic nesting.
+
+2010-12-18  Werner LEMBERG  <wl@gnu.org>
+
+	Improve CJK support with new values for `.cflags'.
+
+	This patch introduces three new values to `.cflags':
+
+	  don't break before character: 128
+	  don't break after character:  256
+	  allow inter-character break:  512
+
+	They are handled differently if compared to other cflags values:
+
+	  (1) hcode values are completely ignored
+	  (2) similar to kern values, and contrary to the other cflags
+	      values, troff looks at pairs of characters to decide whether a
+	      break gets inserted
+
+	A yet-to-be-written patch should add inter-character spacing if
+	those flags are active; currently, only zero-width breakpoints are
+	inserted.
+
+	* src/roff/troff/charinfo.h (charinfo): Change type of `flags' to
+	`int'.  Update callers accordingly.
+	New enum values `DONT_BREAK_BEFORE', `DONT_BREAK_AFTER', and
+	`INTER_CHAR_SPACE'.
+	New member functions `prohibit_break_before',
+	`prohibit_break_after', and `inter_char_space'.
+	* src/roff/troff/input.cpp: Updated.
+
+	* src/roff/troff/node.cpp (inter_char_space_node): New class similar
+	to kern_pair_node, collecting charinfo entities with the
+	abovementioned cflags values.
+	(break_char_type): Add new enum values.
+	(glyph_node::merge_glyph_node): Handle abovementioned cflags values
+	and emit an `inter_char_space_node' if necessary.
+
+	* tmac/ja.tmac: Use new cflags values.
+
+	* doc/groff.texinfo, NEWS, man/groff_diff.man: Document new values.
+
+2010-12-18  Werner LEMBERG  <wl@gnu.org>
+
+	Remove compiler warning.
+
+	* src/libs/libgroff/relocate.cpp (msw2posixpath): Remove redundant
+	dereferencing.
+
+2010-12-16  Daiki Ueno  <ueno@unixuser.org>
+
+	Don't change srcdir if building in a separate builddir.
+
+	* Makefile.in ($GNULIBDIRS): Copy configuring stuff of gnulib if
+	necessary.
+
+2010-12-15  Werner LEMBERG  <wl@gnu.org>
+
+	Fix compilation problem.
+
+	This issue happens with gcc 4.2.4.
+
+	* src/roff/troff/node.cpp (node::~node): Move to...
+	* src/roff/troff/node.h: Here.  This ensures that the inline
+	member function is publicly visible.
+
+2010-12-15  Werner LEMBERG  <wl@gnu.org>
+
+	Remove unused code.
+
+	* src/roff/troff/node.cpp, src/roff/troff/node.h
+	(space_node::space_node): Remove unused constructor.
+
+2010-12-15  Werner LEMBERG  <wl@gnu.org>
+
+	Use enum to increase readability.
+
+	* src/roff/troff/node.cpp (break_char_type): New enum.
+	(break_char_node::add_self, node::add_char): Use it.
+
+2010-12-13  Daiki Ueno  <ueno@unixuser.org>
+	    Werner LEMBERG  <wl@gnu.org>
+
+	Add wide character support to grotty.
+
+	This is a huge patch, mainly by adding the gnulib infrastructure in
+	a separate directory tree (in `src/libs/gnulib/lib') for its
+	`wcwidth' module.  However, the actual changes to native groff
+	source files are just a few lines.
+
+	* Makefile.comm (INCLUDES): Updated.
+	(LIBGNU): Define.
+
+	* Makefile.in (NOMAKEDIRS): Updated.
+	(GNULLIBDIRS): Define.
+	(DISTDIRS): Add GNULLIBDIRS.

+	* src/devices/grotty/Makefile.sub (XLIBS): Add LIBGNU.
+	* src/devices/grotty/tty.cpp (main): Set LC_CTYPE.
+
+	* src/libs/gnulib/*: New files.  The import was done as follows:
+
+	  . Call
+
+	      gnulib-tool --create-testdir \
+	                  --dir=src/libs/gnulib \
+	                  wcwidth
+
+	    to get a testbed.
+
+	  . Manually move directories src/libs/gl{lib,m4} to
+	    src/libs/{lib,m4}, and do s/gllib/lib/ and s/glm4/m4/ everywhere
+	    to `convert' the gnulib testbed to a standard gnulib
+	    configuration as maintained by gnulib-tool.
+
+	  . Call
+
+	      gnulib-tool --add-import \
+	                  --dir=src/libs/gnulib \
+	                  wcwidth
+
+	    to update everything.
+
+2010-12-13  Werner LEMBERG  <wl@gnu.org>
+
+	`.class' must not emit empty lines.
+
+	* src/roff/troff/input.cpp (define_class): Add missing `skip_line'
+	calls.
+

+	    Colin Watson  <cjwatson@debian.org>
+
+	Add Japanese localization.
+
+	* tmac/ja.tmac: New file.

+
+2010-12-06  Colin Watson  <cjwatson@debian.org>
+	    Daiki Ueno  <ueno@unixuser.org>
+
+	Implement support for character classes.
+
+	This patch uses standard C++ headers, contrary to the rest of groff.
+	Ideally, everything in groff should be updated to do the same.
+
+	* src/include/font.h (glyph_to_unicode): New function.
+
+	* src/libs/libgroff/font.cpp (glyph_to_unicode): Implement it.
+	(font::contains, font::get_code): Use it.
+
+	* src/roff/troff/charinfo.h: Include <vector> and <utility>.
+	(charinfo): New members `ranges' and `nested_classes'.
+	New member functions `get_unicode_code' and `get_flags'.
+	New member functions `add_to_class', `is_class', and `contains'.
+	(charinfo::overlaps_horizontally, charinfo::overlaps_vertically,
+	charinfo::can_break_before, charinfo::can_break_after,
+	charinfo::can_break_after, charinfo::ends_sentence,
+	charinfo::transparent,, charinfo:ignore_hcodes): Use `get_flags',
+	which handles character classes also.
+
+	* src/roff/troff/input.cpp (char_class_dictionary): New global

+
+	The original code appears to have been intended to deal with the
+	situation when radius is orders of magnitude less than `d'.  The

+=======================
+
+2018-12-18 Bertrand Garrigues <bertrand.garrigues@laposte.net>
+
+	Fix 'dvi' and 'pdf' texinfo doc generation.
+
+	GNU make has a built-in variable 'TEXI2DVI' but it is not the case
+	of all 'make' implementations, which causes 'make doc' to fail
+	with an unclear message although 'texi2dvi' is available.  Also,
+	'texi2dvi' is invoked inconditionnally.
+
+	* m4/groff.m4 (GROFF_TEXI2DVI): new macro to detect properly the
+	presence of 'texi2dvi'.
+
+	* configure.ac: use 'GROFF_TEXI2DVI' and define automake conditional
+	'HAVE_TEXI2DVI'.
+
+	* doc/doc.am:
+	- Define TEXI2DVI to 'texi2dvi'.
+	- Print an error message if 'texi2dvi' is not available.
+
+2018-12-14  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* doc/groff.texi: Drop documentation of "man" macro package from
+	  our Texinfo manual.  The mdoc, me, mm, and mom packages all
+	  maintain their documentation externally to this manual as
+	  well.  Exception: portions not about man proper--which are not
+	  duplicated from groff_man(7)--on use of man.local (including
+	  examples of Ultrix-compatible macros) are retained.
+
+2018-12-08 Bertrand Garrigues <bertrand.garrigues@laposte.net>
+
+	Install texinfo doc on 'make install-pdf' and 'make install-html'
+
+	* doc/doc.am:
+	- Use automake 'install-pdf-local' and 'install-html-local' rules
+	to install groff.pdf and groff.html
+	- New rules 'uninstall_pdf' and 'uninstall_html'.
+	- Use $(RM) instead of 'rm'.
+	- Don't try to build doc if 'BUILD_INFODOC' is not set.
+	* INSTALL.REPO: document texinfo build and installation.
+
+2018-12-10 Ingo Schwarze <schwarze@openbsd.org>
+
+	* Makefile.am: Remove the unused variables PREFIXMAN5 and PREFIXMAN7.
+
+	They caused installation failures on Solaris 9.
+
+2018-12-08 Bertrand Garrigues <bertrand.garrigues@laposte.net>
+
+	Remove gnulib's hypot module.
+
+	The removal of 'GROFF_NEED_DECLARATION([hypot])' in 'configure.ac'
+	was correct as the test was buggy, but there is no need to use
+	gnulib's hypot module as previously we did not need to provide a
+	replacement function.
+
+	* bootstrap.conf: do it.
+
+2018-12-08  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	Problem running gropdf on big endian (Sparc)
+
+	* src/devices/gropdf/gropdf.pl: Prior to perl v5.9 the 'L<'
+	template for 'unpack' was unavailable. Solaris 10 uses v5.8.4
+	so safer to use the template 'V' rather than 'L<'.
+
+2018-12-08 Bertrand Garrigues <bertrand.garrigues@laposte.net>
+
+	Use gnulib's 'hypot' module.
+
+	In 'configure.ac', the macro call
+	'GROFF_NEED_DECLARATION([hypot])' checks whether the function
+	'hypot' is correctly declared in 'math.h', but the test is buggy
+	and may yields false results.
+
+	* bootstrap.conf: add 'hypot' module.
+
+	* configure.ac: Remove GROFF_NEED_DECLARATION([hypot]).
+
+	* src/libs/libgroff/hypot.cpp: remove declaration of hypot.
+
+2018-12-07  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	Problem running gropdf on big endian (Sparc)
+
+	* src/devices/gropdf/gropdf.pl: When loading a binary (.pfb)
+	font for embedding always use little endian to unpack chunk
+	headers.
+
+2018-12-05  Bertrand Garrigues <bertrand.garrigues@laposte.net>
+
+	Skip mom tests if needed config is missing.
+
+	* contrib/mom/examples/test-mom.sh.in: exit 77 if URW fonts are
+	not available.
+
+	* contrib/mom/mom.am: distribute inconditionnally test-mom.in.
+
+	* m4/groff.m4 (GROFF_URW_FONTS): check if 'awk' and 'gs' are
+	available, and replace non-portable 'grep' command by awk script.
+
+2018-12-01  Colin Watson  <cjwatson@debian.org>
+

+
+	* bootstrap.conf: Bump Autoconf dependency to 2.68.  We need it
+	to support our bug-reporting URL, which contains a "?".
+	Strictly, Autoconf 2.65 is fine, but 2.66 and 2.67 broke this.

+
+2018-11-12  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* makevarescape.sed:
+	  - Escape plain spaces and double-quotes (ASCII 32 and 34) so
+	    that bad things don't happen if they are embedded in a Make
+	    variable expanded in a man page @THUS@ _and_ given as an
+	    argument to a macro that distinguishes its parameters, such
+	    as .IR.
+	  - Add discretionary breaks after groups of slashes not
+	    preceded by a space; e.g., transform "/usr/bin/groff" into
+	    "/usr/\:bin/\:groff".  Will also work on URLs
+	    {"https://\:example.com/\:page.html"} in case we need that.

+
+	Stop spelling "Unix" as "UNIX".
+
+	Per AT&T Bell Labs veterans Doug McIlroy and Meg McRoberts,
+	spelling "Unix" in full caps was a contrivance insisted upon by
+	AT&T lawyers, and not a practice used in the Unix manuals
+	themselves or the Bell Labs Technical Journal.  See
+	  https://lists.gnu.org/archive/html/groff/2015-01/msg00026.html
+	and
+	  https://lists.gnu.org/archive/html/groff/2015-01/msg00029.html
+	for support.
+
+	There are instances I did _not_ change; they may require further
+	review.
+		ChangeLog.*
+		NEWS
+			One reference relevant to mdoc; see below.
+		doc/meintro{,_fr}.me
+			These documents also give the small caps
+			treatment to groff, troff, and nroff, suggesting
+			a separate changeset.
+		src/preproc/pic/pic.ypp
+			Contains a comment referring to "Compaq Tru64
+			UNIX"; not worth the candle IMO.
+		tmac/s.tmac:
+			{ms macro package} Leaving UX macro definition
+			alone until/unless it can be established that
+			this doesn't change the rendering of historical
+			documents in an objectionable way.
+		tmac/doc-syms-u:
+		tmac/doc-old.tmac-u:
+		tmac/doc-common-u:
+		tmac/groff_mdoc.7.man:

+
+	man pages: Escape interpolated Make variables.
+
+	* makevarescape.sed: Transform - to \-, ~ to \(ti, and so forth,
+	{with an extra layer of backslashes--see below} so that Makefile
+	variables containing ASCII characters that do not represent
+	themselves literally in *roff (see groff_char(7)) are correctly
+	interpolated into man page text.
+
+	* Makefile.am (.man): Transform Makefile variables with the
+	above script when interpolating them into man page text.
+
+	Note that while the script, combined with this target, will
+	transform ` to \(ga, including grave accents in Makefile
+	variables is likely to fail when the shell lexes the argument to
+	echo within the old-style command substitution ``.  Testing
+	shows that grave accents should work[1] if POSIX-style command
+	substitution $() is done instead.  However, $() is less
+	portable.  (Triple-escaping grave accents \\\` inside the
+	interpolated Makefile variable will work, but is not attempted
+	at present.)
+
+	Note also that the amount of backslash-escaping in the sed
+	script is excessive (and incorrect) for normal purposes, but
+	required here because a command substitution is being nested
+	inside yet another invocation of sed.
+
+	{1} For this target; no assurances about the good behavior of
+	unusual characters in Makefile variables in other aspects of the
+	groff build are offered.

+	Fixes <https://savannah.gnu.org/bugs/index.php?55004>.
+
+2018-11-06  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/utils/lookbib/lookbib.cpp: Doesn't make much sense to mark
+	Version_string as a C extern if you're just going to hide it in
+	a throwaway scope again.  Remove braces, exposing it.
+
+	"lookbib -v" now reports a version number, instead of "(null)".

+2018-11-06  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* src/libs/libgroff/error.cpp (do_error_with_file_and_line):
+	If:
+	  a program name is known;
+	but
+	  no file is being processed or the line number is negative,
+	then there was no space between the program name (with colon),
+	and the succeeding diagnostic message.
+
+	Example: lookbib:fatal error: no databases

+
+	Make strip.sed operate only if given permission.
+
+	* tmac/strip.sed: Do nothing whatsoever to any input file that
+	lacks a line matching "%beginstrip%".  This implements a
+	contract between the macro file writer and the stripper script
+	{roff input is not parseable with crude weaponry like regular
+	expressions}.  In practice, most of the changes performed by the
+	script were already in a block enforcing this.  My changes:
+	- Stop unconditionally inserting a roff comment noting the
+	  reader of stripping at line 2.  Instead, replace the line
+	  matching "%beginstrip%" with this comment if and only if it
+	  is present.
+	- Stop deleting lines containing only the empty request if
+	  they occur before "%beginstrip%".
+	- Tweak the wording of the roff comment.
+	- Remove comment within the sed script; see
+	  https://lists.gnu.org/archive/html/groff/2017-11/msg00057.html
+	  and the sed section of "Limitations of Usual Tools" in the
+	  GNU Autoconf Manual.

+
+	* tmac/an-old.tmac: When emitting diagnostics, report the name

+	Gislason for part of the patch.
+
+	Fixes <https://savannah.gnu.org/bugs/?54175> and continues the

+
+	* doc/meintro_fr.me: Add encoding hint to top of file so preconv
+	works correctly even if the build environment's encoding is not
+	UTF-8.  Adapted from Bjarni Ingi Gislason's patch.  Also add
+	long-form Emacs coding declaration at end of file.  Vim's
+	auto-detection seems to be fine, so did not update its modeline.

+
+2018-11-04  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* tmac/groff_man.7.man: Reorganize and largely rewrite to more
+	precisely document the macro package's behavior and to be more
+	helpful and accessible to man page writers who may never read
+	any other groff documentation.
+
+2018-10-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	Clarify meaning of \p escape.  Also make more explicit that line

+
+	Remove #! lines from non-executable files
+
+	These are always invoked by the build system (either in-tree or via
+	the installed Makefiles) using the necessary program, so the #!
+	lines were unnecessary.  They were harmless except that they caused
+	Debian's `lintian` tool to complain about installed non-executable
+	scripts.
+
+	* font/devlj4/generate/special.awk: Remove #! line.

+
+	doc: stop generating W3C validation icons
+
+	Debian's `lintian' tool says:
+
+	  These badges may be displayed to tell readers that care has been
+	  taken to make a page compliant with W3C standards.  Unfortunately,
+	  downloading the image from www.w3.org might expose the reader's IP
+	  address to potential tracking.
+
+	I think the risk is a small one, but I also don't think the badges
+	are especially valuable, so it doesn't seem like much to ask to just
+	drop them at least for groff's own documentation.
+
+	* doc/doc.am (.ms.html, doc/pic.html): Remove `-P-V' option.
+
+2018-03-01  Deri James  <deri@chuzzlewit.myzen.co.uk>

+
+	Use gnulib script 'git-version-gen' to define groff's version
+
+	* bootstrap.conf: add 'git-version-gen' script.
+
+	* configure.ac: suppress 'GROFF_VERSION_STRING' and replace it by
+	the script.  If the current commit corresponds to a tag, then the
+	version is simply the tag name.  Otherwise the version has the

+
+	[mdoc]: rewrite the implementation of the .Lk macro
+
+	* tmac/doc.tmac-u (Lk): Rewrite.
+
+	The old implementation was written before the big mdoc
+	rewrite for groff-1.17.  In contrast to most other macros,
+	it was never updated to use the new techniques.
+	This new implementation makes .Lk callable, makes trailing
+	punctuation work in the normal way, and makes the style of
+	the implementation consistent with other macros.
+
+	It also removes the feature of automatically switching
+	between in-line and displayed rendering depending on the
+	length of the link because that was inconsistent across
+	output modes and counter-intuitive, resulting in ugly
+	output for many existing real-world manual pages.
+	It now always renders in-line.  Use .D1 Lk where desired.
+
+	Merging http://savannah.gnu.org/bugs/?52849
+	OK wl@gnu, jmc@openbsd, bentley@openbsd
+
+2017-12-14  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	man pages: Comment compatibility-mode switching.
+
+	The '.do' and '.cp' requests (both groffisms) are some of the
+	more obscure features of groff's own man page corpus.
+	Consequently, they get cargo-culted around, within and outside
+	groff.  Thanks to Werner Lemberg for the discussion, which
+	revealed (to me) that groff ships with compatibility mode on by
+	default on Solaris 10 and 11.

+
+	* src/preproc/soelim/soelim.1.man: Make .mso request only after

+
+2017-11-19  G. Branden Robinson <g.branden.robinson@gmail.com>
+

+	mdoc %T: use typographic quotes
+
+	* tmac/doc.tmac-u: Changed \*[q] to \*[Lq] and \*[Rq]
+
+	Citing Anthony J. Bentley:
+
+	The below patch causes -mdoc to generate typographic quotes
+	around a %T (reference title) instead of straight quotes.
+
+	I also submitted similar diffs to mandoc and heirloom troff
+	(which haven't been committed yet).  It would be nice for
+	the major implementations not to differ here, and the change
+	is trivial. 
+
+	It's worth noting that groff's refer(1) already uses typographic
+	quotes around %T with my -ms documents.

+
+	If an mdoc(7) .Bl -tag macro lacks the -width argument, the

+	macro.  Neither the Heirloom nor the mandoc(1) implementation

+
+	Apart from doubts whether lists with variable indentation are
+	typographically sound in the first place, support for variable
+	widths in groff is so restricted that it's practically
+	useless.  For each .It, the width will be the default width of

+	.No if .It is not followed by a macro.

+
+	* tmac/s.tmac: Bugfix of previous commit simplified (and

+
+2016-02-02  Carsten Kunze  <carsten.kunze@arcor.de>
+

+
+	Compatibility Mode rendering of groff manual pages
+
+	* m4/groff.m4 (GROFF_WITH_COMPATIBILITY_WRAPPERS): New macro to
+	implement 'configure' option
+	'--with-compatibility-wrappers=<value>'.  With this option the
+	user can control how groff compatibility wrappers for
+	vendor-provided non-GNU macro sets are installed.
+
+	* configure.ac: Use new macro GROFF_WITH_COMPATIBILITY_WRAPPERS.
+
+	* Makefile.am: Define tmac_*_prefix if 'compatibility_wrappers' is
+	set to 'yes'.
+
+	* tmac/tmac.am: Use 'compatibility_wrappers' to control the

+
+	- If set to `no', the groff-provided macro set are installed in

+	name.
+
+	- If set to `yes', the groff-provided macro set are installed in

+	$(tmac_prefix) (which is usually `g') and the generated
+	compatibility wrappers are installed in

+
+	Fix Savannah bug #44768 (Solaris 10 compatibility issues).
+
+	* m4/groff.m4 (GROFF_DIFF_D): new macro to check if `diff' has
+	option -D, and search for `gdiff' if not (new variable DIFF_PROG
+	will contain the `diff' program to be used).
+
+	* m4/groff.m4 (GROFF_HAVE_TEST_EF_OPTION): new macro to check if
+	`test' supports the option -ef (created new variable
+	HAVE_TEST_EF_OPTION).
+
+	* m4/groff.m4 (GROFF_BASH): new macro to search for `bash' (new
+	variable BASH_PROG will contain the full path to `bash' or
+	`/bin/sh' if `bash' was not found).
+
+	* configure.ac: use the 3 new macros defined in m4/groff.m4.
+
+	* contrib/gdiffmk/gdiffmk.am: set HAVE_TEST_EF_OPTION, BASH_PROG,
+	DIFF_PROG in the generated script `gdiffmk'.
+
+	* contrib/gdiffmk/gdiffmk.sh:
+	- Fix incorrect space after '!' in sed script regex.
+	- `test -ef' is not portable: If `bash' is not available and the
+	shell does not support `test -ef', the option to pass a third
+	argument as the output file is disabled.
+	- Report an error if `diff' does not support -D option.
+	- GNU diff and Solaris diff support -D, but #ifndef / #endif are
+	treated differently (GNU adds a '!' in the #endif): modify the
+	regexs in the sed script accordingly.

+
+2015-01-30  Bertrand Garrigues  <bertrand.garrigues@laposte.net>
+
+	Automake migration and Gnulib integration.
+
+	Gnulib:
+	- Added gnulib as a git submodule.
+	- Integrated bootstrap scripts from gnulib.
+	- Gnulib m4 directory is now in `gnulib_m4', while Gnulib's .c
+	files are located in `lib'.  `gnulib_m4' and `lib' are generated
+	and distributed.
+
+	Automake:
+	- Removed Makefiles from the old build system.
+	- Converted Makefile.in into Makefile.am.
+	- Converted Makefile.sub files in all directories to a .am file.
+	- Removed configure, src/include/config.hin (now generated).
+	- Removed various helper scripts (config.guess, config.rpath...),
+	now installed by bootstrap in `build-aux'.
+	- Moved aclocal.m4 to acinclude.m4 (aclocal.m4 is now generated).
+	- Makefile in non-recursive style.
+	- Updated INSTALL.REPO (INSTALL is now a symlink to
+	gnulib/doc/INSTALL, original INSTALL file moved to INSTALL.extra)
+	- Added (empty) THANKS, AUTHORS files.
+	- Added a document on the usage of automake in groff in
+	doc/automake.pdf.
+
+	Additional features:
+	- Out-of-source build is supported.
+	- Parallel build is possible (make -j).
+	- Automatic targets from Automake: `make dist', `make distcheck'.
+	- 'make check' is available for automatic testing, gdiffmk's test
+	was plugged to this target.
+	- Auto-detect if make has builtin variable `RM'.

+
+2014-11-29  Werner LEMBERG  <wl@gnu.org>
+
+	Fix previous commit.
+
+	We forgot to test whether the patch works if compiling from
+	scratch...
+
+	Problem reported by Bertrand Garrigues
+	<bertrand.garrigues@laposte.net>.
+
+	* src/include/lib.h (interpret_lf_args, normalize_for_lf): Move
+	declarations to...
+	* src/include/lf.h: This new file.
+
+	* src/libs/libgroff/lf.cpp, src/preproc/pic/pic.h,
+	src/preproc/preconv/preconv.cpp, src/preproc/refer/refer.h,
+	src/preproc/soelim/soelim.cpp, src/preproc/tbl/table.h: Include
+	`lf.h'.
+	Make `lib.h' the first included header file.
+
+	* src/preproc/eqn/eqn.h: Don't include `stringclass.h'.
+	* src/preproc/eqn/main.cpp: Include `stringclass.h' and `lf.h'.
+

+
+2014-11-10  Eli Zaretskii  <eliz@gnu.org>

+
+	My commit '3fe78135c9fe666dadffde2a822b0535d8db6feb' introduced
+	problem in subroutine `TextWid'.  Octal char `\nnn' returns width of
+	4 char string rather than width of single character.
+
+	* src/devices/gropdf/gropdf.pl: Change `TextWid' to recognise octal
+	escaped characters (\nnn).
+
+2014-11-07  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	See bug #43555.
+

+
+2014-11-04  Werner LEMBERG  <wl@gnu.org>
+
+	* src/libs/gnulib/*: Regenerate autotool files.
+
+2014-11-04  Werner LEMBERG  <wl@gnu.org>
+
+Version 1.22.3 released
+=======================
+
+	* NEWS, README, doc/webpage.ms: Updated.
+
+	* doc/texinfo.tex: Updated from `texinfo' repository.
+
+2014-10-29  Bertrand Garrigues  <bertrand.garrigues@laposte.net>
+
+	* Makefile.in (OTHERDIRS): Mention `afmtodit' first.
+
+	Otherwise, some fonts in `devpdf' (`U-*') are not built.
+
+2014-10-26  Eli Zaretskii  <eliz@gnu.org>
+	    Werner LEMBERG  <wl@gnu.org>
+
+	Add Windows `.cmd' wrapper files.
+
+	* arch/mingw/*: New files, provided by Eli.
+
+	* Makefile.in (make_winscripts, make_install_winscripts,
+	make_uninstall_winscripts): New target variables.
+	(MDEFINES): Add them.
+	(OTHERDIRS): Add `arch/mingw'.
+
+	* m4/groff.m4 (GROFF_CMD_FILES): New macro
+	* configure.ac: Call it.
+	* configure: Regenerated.
+
+2014-10-23  Bertrand Garrigues  <bertrand.garrigues@laposte.net>
+
+	Fix `install' and `uninstall' issues.
+
+	* contrib/chem/Makefile.sub (install_data): Fix build with option
+	--with-doc=no passed to configure (target `install_examples'
+	should not be executed).
+
+	* contrib/chem/Makefile.sub (uninstall_sub):  `uninstall' failed
+	if directories to be removed were not present.
+
+	* contrib/gpinyin/Makefile.sub (uninstall_sub): Ditto.
+
+	* contrib/hdtbl/Makefile.sub (GENFILES): generated files should
+	depend on the creation of the `examples' directory.
+
+2014-10-23  Daiki Ueno  <ueno@gnu.org>
+
+	* m4/iconv.m4: Really avoid false detection of non-working iconv.
+
+2014-10-21  Daiki Ueno  <ueno@gnu.org>
+
+	iconv: avoid false detection of non-working iconv
+
+	The INBUF/OUTBUF arguments of iconv can be either 'const char **'
+	or 'char **'.  If CC is g++, the difference causes a compile error
+	and thus leads to a false detection of non-working iconv.
+	Reported by Eli Zaretskii and Werner LEMBERG in:
+	<https://lists.gnu.org/archive/html/bug-gnulib/2014-10/msg00023.html>.
+
+	* m4/iconv.m4 (AM_ICONV_LINK): Try all possible argument types of
+	iconv.  Bump serial number.
+
+2014-10-20  Werner LEMBERG  <wl@gnu.org>
+
+	* src/libs/gnulib/lib/wctype.in.h: Include `config.h'.
+
+	Problem reported by Eli Zaretskii <eliz@gnu.org>.
+
+	This is a temporary hack to make groff compile with MinGW.  After
+	the switch to an automake infrastructure, together with proper use
+	of `gnulib', we can safely replace the patched file with a standard
+	version.
+
+2014-10-19  Doug McIlroy  <doug@cs.dartmouth.edu>
+
+	Fix Savannah bug #42151.
+
+	* src/preproc/eqn/lex.cpp (file_input::read_line): Handle CR/LF.
+	* src/preproc/pic/pic.cpp (file_input::read_line): Ditto.
+
+2014-10-18  Werner LEMBERG  <wl@gnu.org>
+
+	[mdoc] Add Darwin version string for OS X 10.10.
+
+	* tmac/doc-common (doc-operating-system-Darwin-14.0.0): New string.
+
+	* tmac/groff_mdoc.man: Updated.
+
+2014-10-15  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/webpage.ms: Remove obsolete references to tarballs and diffs.
+
+	Reported by Dave Kemper <saint.snit@gmail.com>.
+
+2014-10-15  Colin Watson  <cjwatson@debian.org>
+
+	Always distribute the parts of groff that require X11.
+
+	* Makefile.in (ALLLIBDIRS): Clone from `LIBDIRS', but include
+	src/devices/libxutil unconditionally.
+	(ALLPROGDIRS): Clone from `PROGDIRS', but include
+	src/devices/xditview and src/utils/xtotroff unconditionally.
+	(DISTDIRS): Use `ALLLIBDIRS' and `ALLPROGDIRS' rather than `LIBDIRS'
+	and `PROGDIRS'.
+
+2014-10-14  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Minor update to NEWS for pdfroff.
+
+	* NEWS (pdfroff): Note use of PHASE register, and not pdf:href.map,
+	to choose when to emit toc_relocation control record.
+
+2014-10-13  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	For pdfroff, deduce "--no-toc-relocation" from input stream.
+
+	* NEWS: Add notification; document the effect of changes, as recorded
+	in contrib/pdfmark/ChangeLog.
+
+2014-10-12  Ingo Schwarze  <schwarze@openbsd.org>
+
+	[mdoc] Support `Mdocdate' CVS keyword substitution.
+	This fixes Savannah bug #42968.
+
+	This feature is used for OpenBSD manuals.
+
+	* tmac/doc-common (Dd): Handle `$Mdocdate:' argument.
+
+	* tmac/groff_mdoc.man: Document it.
+
+2014-10-12  Ingo Schwarze  <schwarze@openbsd.org>
+
+	[mdoc] Add `.At III' and `.St -iso8601'.
+	This fixes Savannah bug #42971.
+
+	* tmac/doc-syms: Add corresponding version strings.
+
+	* tmac/groff_mdoc.man: Synchronize.
+
+2014-10-12  Ingo Schwarze  <schwarze@openbsd.org>
+
+	[mdoc] Update operating system release numbers.
+	This fixes Savannah bug #42969.
+
+	* tmac/doc-common: Update NetBSD, OpenBSD, FreeBSD, and DragonFly
+	version strings.
+
+	* tmac/groff_mdoc.man: Synchronize.
+
+2014-10-12  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/Makefile.in: Use `LC_ALL' in addition to `LANG'.
+	Suggested by Steffen.
+
+2014-10-12  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/groff.texinfo: Make PDF version compilable with makeinfo 5.x.
+
+	makeinfo 5.x handles macro expansion better, which changes the way
+	how an \LE macro (for a less-than sign) has to be defined.  However,
+	since we can't be sure that the latest version of `texinfo.tex' gets
+	used with makeinfo 5.x only, we would have to support both 4.x and
+	5.x.  No idea whether this is possible at all...  For this reason,
+	we now simply use @value directly instead of wrapping it into a
+	macro, avoiding any issues.
+
+2014-10-12  Werner LEMBERG  <wl@gnu.org>
+
+	[doc] Protect against picky `sed' programs.
+	Problem reported by Axel Kielhorn <tex@axelkielhorn.de>.
+
+	* doc/Makefile.in (GROFF_BIN_PATH, GROFF): Add `LANG=' to avoid
+	interpretation of non-ASCII characters by sed.
+
+2014-10-12  Michail Vidiassov  <master@iaas.msu.ru>
+
+	* tmac/doc-common: Add new Darwin versions.
+
+2014-10-12  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/groff.texinfo: s/which/that/ where appropriate.
+
+2014-10-12  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/groff.texinfo: Various minor fixes.
+
+	Most of those glitches have been found by comparing the info output
+	from makeinfo 4.13 and the current SVN development version (of
+	makeinfo).
+
+2014-10-12  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/groff.texinfo: Improve indexing.
+
+	Change @DefXXXItem and @DefXXXListEnd macros to not insert an index
+	entry.  New macro variants with a trailing `x' (like `@DefreqItemx')
+	can override this.
+
+	Update macro calls where necessary.
+
+2014-10-12  Werner LEMBERG  <wl@gnu.org>
+
+	[doc] Improve call to generation of `groff.pdf'.
+	Problem reported by Axel Kielhorn <tex@axelkielhorn.de>.
+
+	Since `groff.texinfo' contains latin-1 characters, some sed
+	implementations (like the one used on Mac OS 10.8) fail if called
+	with the wrong locale.  Basically, this is a `texi2dvi' bug, but we
+	can set `LANG' by ourselves to improve the situation.
+
+	* doc/Makefile.in (.texinfo.dvi, .texinfo.pdf): Set `LANG'
+	environment variable to empty string.
+
+2014-10-12  Werner LEMBERG  <wl@gnu.org>
+
+	[doc] Correctly handle `MAKEINFO' environment variable.
+	Bug introduced in commit from 2014-03-29.
+
+	* m4/groff.m4 (GROFF_MAKEINFO): Don't set MAKEINFO to empty string
+	before actually testing it.
+
+	* configure: Regenerated.
+
+2014-10-11  Bertrand Garrigues  <bertrand.garrigues@laposte.net>
+
+	Fix an issue on `make dist'.
+
+	In order to make the tarball, `make dist' copies src/libs/gnulib
+	directories into the `tmp' directory without the `.deps'
+	directories, causing the failure of `make distclean' in
+	tmp/src/libs/gnulib.  Forcing a call to `config.status' recreates
+	the `.deps' directories.
+
+	* Makefile.in (dist): For gnulib, call `config.status' before `make
+	distclean'.
+
+2014-10-11  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* src/roff/grog/*.pl: Remove call from `IPC', use normal system
+	`instead'.
+
+2014-10-11  Guillem Jover  <guillem@hadrons.org>
+
+	Add support for various BSD versions.
+
+	* tmac/doc-common: Add new FreeBSD and DragonFly versions.
+
+2014-10-11  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Refactor .psbb request handling code.
+
+	* src/roff/troff/input.cpp (do_ps_file): Reimplement it, using...
+	(psbb_locator): ...this new locally declared and implemented class;
+	its constructor replaces all `do_ps_file()' capability, delegating
+	to other class methods, as appropriate.
+	(assign_registers): Encapsulate it, as a `psbb_locator' method.
+	(ps_get_line): Likewise, also renaming it to become...
+	(get_line): ...this class method; its internally defined `lastc'
+	static variable also becomes a non-static class member variable.
+	(PSBB_RANGE_IS_BAD, PSBB_RANGE_IS_SET, PSBB_RANGE_AT_END): New
+	manifest constants; define them.  They are now used by...
+	(parse_bounding_box): ...this function, now also encapsulated as
+	a `psbb_locator' class method, to convey parsing status.
+	(bounding_box): Struct obsoleted by `psbb_locator'; delete it.
+	(ps_bbox_request): Delegate to `psbb_locator'.
+
+2014-10-11  Werner LEMBERG  <wl@gnu.org>
+
+	Various clean-ups.
+
+	* NEWS: More updates.
+
+	* REVISION: Set to 3.

+2014-10-11  Werner LEMBERG  <wl@gnu.org>
+
+	* NEWS, MANIFEST: Updated.
+
+2014-10-11  Werner LEMBERG  <wl@gnu.org>
+
+	* Makefile.in (OTHERDIRS, NOMAKEDIRS): Remove `ideal' references.
+
+2014-10-10  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* contrib/gideal: Temporarily remove this directory, because the
+	documentation and the preprocessor are not yet finished for
+	groff-1.2.23.
+
+2014-10-10  Werner LEMBERG  <wl@gnu.org>
+
+	* Makefile.in (dist): Clean up `src/libs/gnulib'.
+
+2014-10-10  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/webpage.ms: Updates.
+
+	The README and NEWS sections are not yet synchronized, though.
+
+2014-10-09  Ingo Schwarze  <schwarze@openbsd.org>
+
+	* Makefile.in: Let `clean' and `distclean' descend into gnulib.
+
+	This fixes Savannah bug #42970.
+
+2014-10-02  Bertrand Garrigues  <bertrand.garrigues@laposte.net>
+
+	Set default X11 resources dir to `$prefix/lib/X11/app-defaults'.
+
+	Previously, X11 resources for gxditview were installed in
+	`/usr/X11/lib/X11/app-defaults', no matter which prefix was set.
+
+	Now, gxditview resources are installed in
+	`appresdir=$prefix/lib/X11/app-defaults'.  If `appresdir' is not a
+	standard X11 resource directory, the environment variable
+	`XFILESEARCHPATH' should be set to this path.
+
+	The behaviour of `--with-appresdir' is unchanged: This option can
+	still be used to set `appresdir', and its value will not be modified
+	by the prefix.
+
+	* m4/groff.m4 (GROFF_APPRESDIR_DEFAULT): Implement new behaviour.
+	Fix detection app-defaults location on the system.
+	(GROFF_APPRESDIR_CHECK): Updated.
+
+	* configure.ac: Improve output of configuration.
+	* configure: Regenerated.
+
+	* NEWS: Mention it.
+
+2014-09-27  Werner LEMBERG  <wl@gnu.org>
+
+	Set `transparent' flag for `\[cq].
+	Problem reported by Dave Kemper <saint.snit@gmail.com>.
+
+	* src/roff/troff/input.cpp (init_charset_table): Do it.
+
+	* doc/groff.texinfo (Sentences, Using Symbols), man/groff_diff.man:
+	Document it.
+
+2014-09-25  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* src/roff/grog/*.pl: Program more reasonable subs (functions).
+	Repair details in many places.
+
+2014-09-24  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Refactor psbb line input function; avoid a buffer overrun.
+
+	* src/roff/troff/input.cpp (ps_get_line): Declare it as `static'.
+	Refactor, to avoid the overhead of character look-ahead and push-back
+	on CR stream input.  Add new `dscopt' parameter, in place of internal
+	`err' variable; update all call references, passing value of...
+	(DSC_LINE_MAX_ENFORCE): ...this new manifest constant; define it.
+	(DSC_LINE_MAX_IGNORED): Likewise; currently unused, but intended for
+	future use as an alternative to `DSC_LINE_MAX_ENFORCE'.
+	(DSC_LINE_MAX_CHECKED): New manifest constant; used internally only.
+	(PS_LINE_MAX): Manifest constant, renamed for notional consistency...
+	(DSC_LINE_MAX): ...to this; defined value remains as 255.
+	(do_ps_file): Increase stack allocation for `buf' char array; former
+	allocation of PS_LINE_MAX (now DSC_LINE_MAX) bytes exposed a potential
+	buffer overrun, after reading DSC_LINE_MAX bytes; two additional bytes
+	are required, to accommodate a terminating LF and NUL.  Add `dscopt'
+	parameter, with value `DSC_LINE_MAX_ENFORCE', in each of three calls
+	to `ps_get_line()'.
+
+2014-09-20  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* src/roff/groff/Makefile.sub: Remove too much deleting while
+	running `make'.
+
+2014-09-20  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* `Makefile.sub' in the whole groff source tree: Add $(RM) and
+	change all `rm -f'.  Add directory test before `rmdir'.
+
+2014-09-20  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* Man-pages (*.man) in the whole groff source tree: Improve
+	documents by adding \[co], \[cq], \[aq] instead of ` or ' and use
+	also \[co] as long as it makes sense.  Remove \[en] in the years
+	date in order to allow the automatic license year increasing.
+

+
+	* */Makefile.*: Path quoting fixes, whitespace, formatting.

+
+2014-04-03  Steffen Nurpmeso  <sdaoden@yandex.com>
+
+	* Makefile.comm (extraclean): Don't delete `old'.
+
+	The rule calling `rm -f' was originally thought to remove private,
+	temporary files.  However, we now have a subdirectory called `old'
+	in `fonts/devps' that may not be removed, and trying so now causes
+	an error because we no longer ignore the returned error code of

+
+	See

+
+	for more.
+
+	* tmac/an-old.tmac (set-an-margin): Whenever (re)setting
+	`\n[an-level]' to 1 (which happens when encountering `.TH', `.SH',
+	and `.SS') make sure to also (re)set `\n[an-saved-margin1]' and
+	`\n[an-saved-prevailing-indent1]' to a sane value such that an
+	immediate `.RE' cannot wreak havoc.
+	(TH, SH, SS): Updated.
+
+2014-03-11  Ingo Schwarze  <schwarze@openbsd.org> (tiny change)
+
+	* Makefile.in: Do not forget to install gropdf manuals.
+
+	This got broken in 290eaaac6cfc33856cd683838accc72ccf3e5a84:
+	src/devices/gropdf was split out of OTHERDIRS into SHPROGDIRS, and
+	consequently, Makefile.man was no longer used there.  Note that
+	Makefile.dev is *not* needed, even though it's below /devices/.
+
+2014-03-11  Ingo Schwarze  <schwarze@openbsd.org> (tiny change)
+
+	* src/roff/groff/Makefile.sub: POSIX conformance.
+
+	- POSIX says that the meaning of the make(1) `$<' macro shall be
+	   unspecified except in inference rules.  Consequently, use `$?'
+	   for portability.
+
+	   That's safe because the rules have only one prerequisite and
+	   are not `.PHONY', so `$?' will always expand to one item.
+
+	- While here, clean up two instances of superfluous use of cat(1).
+
+2014-03-11  Ingo Schwarze  <schwarze@openbsd.org> (tiny change)
+
+	* Makefile.in (dist): Improve.
+
+	- Bugfix: Do not error out if one of the DISTDIRS
+	   contains a subdirectory.
+	- Make debugging easier by splitting the huge "cd tmp; ...; ..."
+	   command sequence into several independent shell commands,
+	   such that one can see which command actually fails.
+
+2014-03-06  Deri James  <deri@chuzzlewit.myzen.co.uk>

+2014-02-26  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* src/roff/grog/grog.pl: Add detection of `gperl' to `grog'.
+
+2014-02-25  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* contrib/gperl: New preprocessor for Perl parts in groff files.
+
+2014-02-15  Ingo Schwarze  <schwarze@openbsd.org>
+
+	* tmac/groff_mdoc.man: Improve the manual page template.
+
+	 - Add the EXIT STATUS section.  It is widely used in at least
+	   NetBSD, FreeBSD, OpenBSD, and DragonFly manuals.
+	 - Recommend the DIAGNOSTICS section for section 4 manuals.  Such
+	   usage is very widespread, in particular for kernel printf
+	   messages emitted by device drivers.
+	 - Do not recommend the DIAGNOSTICS section for command return
+	   values to the shell any longer.  While such usage historically
+	   existed, it does not seem common nowadays, and in any case, using
+	   the now well-established EXIT STATUS section seems preferable to
+	   me.
+	 - Mention the possibility to use ERRORS for section 4 manuals.
+	   While most section 4 manuals have a DIAGNOSTICS section, only
+	   some will need an ERRORS section, but these cases aren't exactly
+	   rare, either.  Quite some device driver manuals explain how to
+	   use the device using system calls like ioctl(2), open(2), read(2)
+	   or write(2), in which case the ERRORS section is the natural
+	   place to explain which errno values the driver may set during
+	   such system calls.
+	 - Mentioning signal handling as a content of the ERRORS section
+	   seems redundant, it is already covered by talking about the
+	   errno.  The case of errno == EINTR should be handled just like
+	   all other errno cases.  For an example showing that there is no
+	   need to single out error handling in any way, please look at a
+	   typical read(2) manual page.
+	 - Mention the CAVEATS section.  It first appeared in the 4.2BSD
+	   execve(2) manual in 1983, was already used by several manuals by
+	   the time of 4.4BSD-Lite2 in 1995, and is in whidespread use
+	   today, not just in BSD base system manuals, but for example in
+	   Perl manuals as well.

+2014-02-14  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* src/roff/grog/grog.pl: Add detection of glilypond-parts in groff

+
+2014-02-12  Bernd Warken  <groff-bernd.warken-72@web.de>

+	Useful changes will be re-committed in smaller, logical chunks.
+
+2014-01-05  Bernd Warken  <groff-bernd.warken-72@web.de>
+

+
+2014-01-04  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* groff/tmac/an-ext.tmac: add new request .FONT for using

+
+2014-01-02  Deri James  <deri@chuzzlewit.myzen.co.uk>

+
+2013-12-06  Mike Frysinger  <vapier@gentoo.org>
+
+	Fix parallel build with gropdf and mom examples.
+
+	The `contrib/mom/examples/' directory uses the helper script from
+	`src/devices/gropdf/'.  Currently though, parallel builds might fail
+	like so:
+
+	  ...
+	  make[2]: Entering directory `.../groff-1.22.2/contrib/mom'
+	  <groff command> examples/letter.mom >examples/letter.pdf
+	  <groff command> examples/mom-pdf.mom >examples/mom-pdf.pdf
+	  /bin/sh: .../groff-1.22.2/src/devices/gropdf/pdfmom: No such file or directory
+	  make[2]: *** [examples/letter.pdf] Error 127
+	  /bin/sh: .../groff-1.22.2/src/devices/gropdf/pdfmom: No such file or directory
+	  make[2]: *** [examples/mom-pdf.pdf] Error 127
+	  make[2]: Leaving directory `.../groff-1.22.2/contrib/mom'
+	  make[1]: *** [contrib/mom] Error 2
+	  ...
+	  make[2]: Entering directory `.../groff-1.22.2/src/devices/gropdf'
+	  sed -f .../groff-1.22.2/arch/misc/shdeps.sed \
+	      -e "s|@VERSION@|1.22.2|" \
+	      -e "s|@PERLPATH@|/usr/bin/perl|" ./pdfmom.pl >pdfmom
+
+	The top level makefile tries to account for this in general with
+	OTHERDIRS, but looks like `src/devices/gropdf/' was added to this
+	variable (which holds `contrib/mom/' too) because gropdf installs a
+	shell script, and the other prog vars require it to be a dir of
+	things to compile.
+

+	`groff_options.info' be installed into the `groff libdir'.
+
+2013-04-16  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* INSTALL.gen: Replace this file by the daily `git' version of
+	`automake' `INSTALL' file.
+
+	* INSTALL.autotools: Remove file.
+
+	* INSTALL.CVS: New file, moved from `INSTALL.autotools'.
+
+	* m4/ax_prog_perl_version.m4: New file, taken from package
+	`autoconf-archive-2013.04.06'.
+
+	* m4/groff.m4: Remove unnecessary blank line.
+
+	* Makefile.in: Add `$(PERLVERSION)'.
+
+	* aclocal.m4: Run `autoreconf -I m4' (this includes
+	`aclocal -I m4').  This creates a suitable `aclocal.m4'.  Remove
+	generated subdirectory `autom4te.cache'.
+
+	* src/roff/grog/Makefile.sub: Correct `sed' command.  Use `tabs'
+	that are needed by `GNU make'.
+
+2013-04-16  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* Makefile.sub: Add `m4/ax_compare_version.m4'.
+
+	* aclocal.m4: Run the latest `aclocal -I m4' which generates a
+	suitable content in that file.
+
+	* INSTALL.autotools: Information of the usage of `GNU autotools'
+	with `groff'.
+
+	* INSTALL.gen: Move `autotool' parts to file `INSTALL.autotools'.
+
+2013-04-15  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* m4/groff.m4: Replace tabs by spaces.  Use a double line between
+	AC_DEFUNs.
+
+2013-04-15  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	In the whole `groff' system, rename autoconf variable `$PERLPATH'
+	to `$PERL', which has the same content.  But `$PERL' suits to
+	`AX_PROG_PERL_VERSION' in m4 macro `GROFF_PERL' in `m4/groff.m4'.
+
+	* src/utils/afmtodit/Makefile.sub,

+	* Makefile.in: Replace `$PERLPATH' by `$PERL'.
+
+	* m4/ax_compare_version.m4: New file, copied from daily version of
+	`GNU autoconf-archive'.
+
+	`autoconf' was not yet run, a newer version is needed.
+
+2013-04-15  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* README, INSTALL, INSTALL.gen, MANIFEST: Add documentation in the
+	top directory about some parts of `autotools' and `glilypond'.
+
+2013-04-15  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* configure.ac: Add information of the macro `GROFF_PERL'.
+
+	* Makefile.in: Add definitions of the macro variables and their
+	`@...@' counterparts.
+
+	Run `autoreconf -I m4'.
+
+2013-04-15  Bernd Warken  <groff-bernd.warken-72@web.de>
+2013-04-15  Werner LEMBERG  <wl@gnu.org>
+2013-04-15  Ralph Corderoy  <ralph@inputplus.co.uk>
+
+	Add Perl test to configuration.  During the run of `configure' the
+	program is broken with error when there is no `Perl' or the `perl'
+	program is too old.
+
+	* m4/groff.m4: Add macro `GROFF_PERL' that tests the availability
+	of the `perl' program and tests whether this has a version of at
+	most `v5.6.1'.  Define variables $PERL and $PERLPATH for the full
+	name of the `perl' program and $PERLVERSION as the lest version.
+
+2013-04-13  Keith Marshall  <keithmarshall@users.sourceforge.net>
+
+	Avoid consideration of autotool cache for CVS inclusion.
+
+	* .cvsignore (autom4te.cache): Add reference.
+
+2013-04-13  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* `autotools': During the run of `autoconf' and `autoreconf' a
+	subdirectory `autom4te.cache' was created.  I first added this to
+	groff CVS and removed it again after an email-discussion.
+
+2013-04-12  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* `grog': Remove the shell version of `grog'.  Now there is only
+	Perl version.
+
+	* src/roff/grog/perl.sh: Remove this file.
+
+	* src/roff/grog/Makefile.sub: This file handles the removement of
+	the shell version.
+
+	* src/roff/grog/perl_test.pl: New file for testing the available
+	Perl version in the system to be installed into.  This file will
+	be installed into the grog lib-directory.
+
+2013-04-12  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* `grog': In the following, the file `grog.pl' will be split.  For
+	the coming files, a lib-directory is needed for storage.
+
+	* m4/groff.m4, configure.ac: Add libdir information for `grog'.
+
+	* Makefile.in: Add @grog_dir@.
+
+	Run `autoconf'.
+
+	`grog' has now a lib-directory at `$prefix/lib/groff/grog'.
+
+2013-04-11  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* contrib/groffer/: There is a free `git' package containing all
+	old `groffer' versions `v0.*' and `v1.*'.  The new versions
+	`groffer 2.*' will actually not be included.  This package can be
+	got at:
+
+	$ git clone git@github.com:RUNOFF/groffer.git
+
+2013-04-11  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* contrib/glilypond/: There is a free `git' package containing all
+	old versions of the former name `groff_lilypond v0.*'.  They work
+	with `lilypond' parts in `roff' files, but were not installed.
+	This package can be got at:
+
+	$ git clone git@github.com:RUNOFF/groff_lilypond.git
+
+	The new versions `glilypond v1.*' are not included there.
+
+2013-04-11  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* man/roff.man: For roff(7), add information about the free git
+	package RUNOFF.git with documentation about historical RUNOFF and
+	the available files written in the classical RUNOFF language..
+
+2013-03-29  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	Rename `groff_lilypond' to `glilypond'.  So remove the former
+	source directory `<groff_src_dir>/contrib/lilypond' and newly
+	install `<groff_src_dir>/contrib/glilypond', which now has many
+	files.  The new version starts at `v1.0'.
+
+	* m4/groff.m4, configure.ac: Add libdir information for
+	`glilypond'.
+
+	* Makefile.in: Add `<groff_src_dir>/contrib/glilypond'.
+
+	Run `autoconf'.
+
+	`glilypond' can now be installed to the system.
+
+2013-03-17  Ingo Schwarze  <schwarze@openbsd.org>
+
+	* font/devpdf/Makefile.sub: Build system fixes.
+
+	(GROFF_FONT_FILES): Avoid installing Makefile.sub.orig when it's
+	around.
+	(install): Create $(DESTDIR)$(fontsubdir)/util when missing.
+
+2013-03-05  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/groff.texinfo: Improve documentation of `\s'.
+
+	Reported by Jim Avera <james_avera@yahoo.com>.
+
+2013-02-16  Werner LEMBERG  <wl@gnu.org>
+

+
+2013-02-13  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/groff.texinfo: Fix if-else example.
+
+	Reported by Jim Avera <james_avera@yahoo.com>.
+
+2013-02-10  Werner LEMBERG  <wl@gnu.org>
+
+	[grops] Make binary `%%BeginData' work; support `fontset' resource.
+
+	* src/devices/grops/psrm.cpp (resource_table): Add `fontset'.
+
+	(resource_manager::read_resource_arg): Do a case insensitive
+	comparison.  The PostScript Reference Manual gives the following
+	example for a CFF resource (example 5.7):
+
+	%!PS-Adobe-3.0 Resource-FontSet
+	%%DocumentNeedResources: ProcSet (FontSetInit)
+	%%Title: (FontSet/CFFRoman27)
+	%%Version: 1.000
+	%%EndComments
+	%%IncludeResource: ProcSet (FontSetInit)
+	%%BeginResource: FontSet (CFFRoman27)
+	/FontSetInit /ProcSet findresource begin
+	%%BeginData: 622532 Binary Bytes
+	/CFFRoman27 622503 StartData
+	... 622,503 bytes of binary data ...
+	%%EndData
+	%%EndResource
+	%%EOF
+
+	Note the `ProcSet' and `FontSet' keywords.  While the old DSC
+	(Document Structure Convention) documentation doesn't cover
+	`FontSet' at all (the DSC documentation predates the invention of
+	CFF), it describes only `procset' (all letters downcase), and it
+	also says that the DSC parser works in a case sensitive manner.
+
+	In other words, `ProcSet' is not valid according to the DSC
+	documentation, only `procset' is.  So much about today's validity
+	of DSC...  This patch adapts grops's code to the PostScript
+	reality.
+
+	(resource_manager::do_begin_data): Fix typo (present since the
+	beginning) which prevented correct handling of binary data.
+
+	* src/devices/grops/ps.h (resource_type): Add RESOURCE_FONTSET.
+
+2013-02-10  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* contrib/lilypond: New files for adding lilypond parts into groff
+	files.
+
+2013-02-07  Werner LEMBERG  <wl@gnu.org>
+
+Version 1.22.2 released
+=======================
+
+	* NEWS, REVISION, doc/groff.texinfo, doc/webpage.ms: Updated.
+
+	* configure: Regenerated.
+
+	* doc/texinfo.tex: Updated from `texinfo' repository.

+
+2013-02-07  Werner LEMBERG  <wl@gnu.org>
+
+	* src/libs/gnulib/*: Update `gnulib' files.
+
+2013-02-02  Gilles Espinasse  <g.esp@free.fr>
+
+	[grohtml] Don't ignore return value of `dup'.
+
+	* src/preproc/html/pushback.cpp (pushBackBuffer::pushBackBuffer,
+	pushBackBuffer::~pushBackBuffer): Abort if `dup' fails.
+
+2013-01-30  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* tmac/groff_man.man: Fix wrong connection for tbl(1).
+
+2013-01-29  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/groff.texinfo: Fix documentation of .LP macro in ms.
+	Problem reported by Omari Norman <omari@smileystation.com>.
+
+2013-01-29  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/Makefile.sub (uninstall_sub): Handle `gnu.eps'.
+
+2013-01-29  Werner LEMBERG  <wl@gnu.org>
+
+	Building clean-ups.
+
+	* Makefile.in: Use $(top_srcdir) where appropriate.
+	* Makefile.sub (M4MACROS): Add `fcntl-o.m4' and `localcharset.m4'.
+
+	* font/devpdf/Makefile.sub (UTILFILES): Removed, unused.
+	(MOSTLYCLEANADD): Add `BuildFoundries'.
+	* src/devices/gropdf/Makefile.sub (MOSTLYCLEANADD): Add `pdfmom'.
+
+2013-01-24  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* Add a shell command to 'MANIFEST' that displays all man source
+	files and their section.
+
+2013-01-22  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* Add email address in all files having the name.
+
+2013-01-14  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	* src/devices/gropdf/gropdf.pl (do_x, do_p, do_s, Set_LWidth): The
+	grops driver defaults to round linecaps and linejoins, gropdf
+	incorrectly used butt caps and miter joins.
+
+	(Since the MOM package expects to use butt caps and miter joins
+	(emitting the necessary postscript code to change the caps and
+	joins), gropdf now parses the same postscript commands.)
+
+	* src/devices/gropdf/gropdf.man: Document the handling of linecaps
+	and linejoins.
+
+	* tmac/pdf.tmac (pdfbookmark): Fix bug where the current
+	PDFOUTLINE.FOLDLEVEL may not be honoured if warnings of the type
+
+	macro warning: adjusted level n bookmark; should be <= n
+
+	Added copyright and mention debt owed to Keith Marshall for
+	original `pdfmark.tmac', upon which `pdf.tmac' is largely based.
+
+	* font/devpdf/Foundry.in, font/devpdf/util/BuildFoundries.pl
+	(LocateFile): The font for EURO had the wrong entry in the
+	`download' file (it pointed to The font in the build directory,
+	which is wrong).  It has always been permissible to include a
+	path along with the font name in the Foundry file, but until now
+	the font had to exist to be valid.  It is now permitted to start
+	the path with an asterisk which tells BuildFoundry to use the
+	path/filename in the download file without checking if the font
+	exists.  This allows the font to be found in `../devps' even
+	though it is not there during the build (if source and build are
+	different), but will be there after the install.
+
+2013-01-13  Werner LEMBERG  <wl@gnu.org>
+
+	[eqn] Fix display of matrices in nroff output.
+
+	Problem reported by Andy Spencer <andy753421@gmail.com>.
+

+	matrix_box::compute_metrics): Fix rounding.
+
+2013-01-07  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	* tmac/europs.tmac: Protect against missing fonts.
+
+2013-01-07  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	* font/devpdf/util/BuildFoundries.pl (LoadFoundry): Improve
+	warning.
+
+2013-01-07  Werner LEMBERG  <wl@gnu.org>
+
+	[tbl] Allow characters #, `, and ' as eqn delimiters.
+
+	While problems ` and ' have been unintentionally introduced rather
+	recently, the limitation regarding # was there from the beginning.
+
+	At the same time, fix a small bug causing `.lf' requests not
+	starting a line.
+
+	* src/preproc/tbl/table.cpp (table::init_output)
+	(table::compute_expand_width, table::compute_separation_factor)
+	(table::define_bottom_macro, table::do_bottom): Temporarily switch
+	off eqn delimiters, wrapping the code into a `.ig' block.  This
+	uses the new functionality just added to eqn.
+
+	* src/preproc/eqn/eqn.man, src/preproc/tbl/tbl.man: Updated.
+
+2013-01-06  Werner LEMBERG  <wl@gnu.org>
+
+	[eqn] Add `delim on'.
+
+	* src/preproc/eqn/lex.cpp (start_delim_saved, end_delim_saved):
+	New global variables.
+	(do_delim): Handle `delim on' to restore previous start and end
+	delimiters.
+
+	* src/preproc/eqn/eqn.man, NEWS: Document it.
+
+2013-01-02  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	[gropdf] Various minor fixes.
+
+	* src/devices/gropdf/gropdf (do_x) <'X'> <'pdfpic'>: Using
+
+	\X'pdf: pdfpic'
+
+	with a zero width now works correctly.
+
+	(LoadPDF): Scale width in proportion to given height.
+
+	(do_s): In some circumstances a font size change is emitted before
+	current font is established.  Fix handles this situation.
+

+
+Version 1.22.1 released
+=======================
+
+	Due to CVE-2012-3386, ftp.gnu.org rejected uploading of version
+	1.22 -- in other words, 1.22 has never been released.
+
+	* NEWS, REVISION, doc/groff.texinfo, doc/webpage.ms: Updated.
+
+	* Makefile.in (NOMAKEDIRS): Updated.
+
+2012-12-30  Werner LEMBERG  <wl@gnu.org>
+
+	* src/libs/gnulib/*: Update `gnulib' files.
+
+	Because we currently don't support `gnulib-tool' directly but add
+	everything to the CVS repository, and many internal details of the
+	gnulib setup has changed, it is necessary to do redo the import.
+
+	. Temporarily rename `src/libs/gnulib' to `src/libs/gnulib.old'.
+
+	. Call
+
+	    gnulib-tool --create-testdir \
+	                --dir=src/libs/gnulib \
+	                wcwidth
+
+	. Manually move directories `src/libs/gnulib/gl{lib,m4}' to
+	`src/libs/gnulib/{lib,m4}', and do `s/gllib/lib/' and `s/glm4/m4/'
+	in all files to `convert' the gnulib testbed to a standard gnulib
+	configuration as maintained by gnulib-tool.  Additionally, remove
+	the directory `src/libs/gnulib/gltests' and the references to
+	`gltests' in all files.
+
+	(All of this could be done with a script, but I hope that this is
+	eventually replaced with migrating groff as a whole to gnulib and
+	its setup).
+
+	. Call
+
+	    gnulib-tool --add-import \
+	                --dir=src/libs/gnulib \
+	                wcwidth
+
+	to update everything.
+
+	. Merge the changed, new, and deleted files into `gnulib.old',
+	delete `gnulib', rename `gnulib.old' to `gnulib', then commit.
+
+2012-12-28  Werner LEMBERG  <wl@gnu.org>
+
+	[doc] More documentation generation rules.
+
+	* doc/Makefile.in (.texinfo.txt): New rule.
+	(.texinfo.html): Use `LANG='.
+	(split-html): New target.
+
+2012-12-28  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/fixinfo.sh: Make it work with makinfo 4.13 also.
+
+2012-12-28  Werner LEMBERG  <wl@gnu.org>
+
+	Split ChangeLog.
+
+	* ChangeLog: Split off older entries into...
+	* ChangeLog.121: this new file.

+
+	* src/devices/gropdf/pdfmom.pl: Support use of GROFF_BIN_PATH.
+
+2012-09-11  Ralph Corderoy  <ralph@inputplus.co.uk>

+
+2012-08-31  Deri James  <deri@chuzzlewit.myzen.co.uk>

+
+	TBLization, as discussed on the list.  There's a rewrite of
+	this file in planning, but this gets the content clean for now.
+
+	* tmac/groff_mdoc.man: In this file.
+
+2012-08-09  Werner LEMBERG  <wl@gnu.org>
+
+	Provide proper Unicode mapping from and to dotless j.
+
+	* src/libs/libgroff/glyphuni.cpp (glyph_to_unicode_list),
+	src/libs/libgroff/uniglyph.cpp (unicode_to_glyph_list): Add it.
+
+2012-08-08  Eric S. Raymond  <esr@thyrsus.com>
+
+	Added Unicode code point for dotless j.
+
+	* man/groff_char.man: In this file.
+
+2012-08-08  Werner LEMBERG  <wl@gnu.org>
+
+	* man/groff_char.man: Clean-ups.
+
+2012-08-08  Eric S. Raymond  <esr@thyrsus.com>
+
+	Elimination of nasty presentation-level macro tangles makes
+	structural translation to XML possible.
+
+	* man/groff_char.man: Clean up the mess, use real TBL tables.
+
+2012-07-23  Eric S. Raymond  <esr@thyrsus.com>
+
+	More elimination of low-level troff hackery in the documentation
+	so it can be lifted to structural markup.
+
+	* tmac/groff_me.man: Use TBL rather than wacky diversions and .ti
+	requests.
+
+2012-07-24  Werner LEMBERG  <wl@gnu.org>
+
+	Fix appearance of groff.texinfo's HTML output.
+
+	Cartouches within an `example' environment don't work.
+
+	* doc/groff.texinfo (CartoucheExample, endCartoucheExample): New
+	macros.  Use them where appropriate.
+
+2012-07-17  Ingo Schwarze  <schwarze@usta.de>
+
+	[mdoc] Make `Fl' correctly restore fonts.
+
+	* tmac/doc.tmac (doc-flag-recursion): Do it.
+
+2012-07-07  Eric S. Raymond  <esr@thyrsus.com>
+
+	* src/preproc/eqn/eqn.man, src/preproc/grn/grnn.man,

+	src/devices/grops/grops.man, src/utils/lkbib/lkbib.man,
+	src/utils/indxbib/indxbib.man, src/utils/tfmtodit/tfmtodit.man,
+	src/utils/xtotroff/xtotroff.man:
+	Remove running text in the synopses of various manual pages,
+	as it badly screws up attempts to mechanically parse them.
+
+	* contrib/mom/groff_mom.man: Use .URL rather than .UR/.UE, as this
+	is now preferred for manual pages.
+
+2012-07-03  Werner LEMBERG  <wl@gnu.org>
+
+	Fix Unicode mapping of Greek stroked and curly phi.
+
+	Problem reported by Alkis Georgopoulos <alkisg@gmail.com>;
+	see
+
+	https://bugs.launchpad.net/ubuntu/+source/groff/+bug/1008115
+
+	* src/libs/libgroff/uniglyph.cpp (unicode_to_glyph_list): Flip
+	values of U+03C6 and U+03D5.
+
+2012-06-13  Deri James  <deri@chuzzlewit.demon.co.uk>
+
+	* src/devices/gropdf/gropdf.pl: When using variable page
+	sizes (with \X'papersize ...') ensure final page is correct
+	size.
+
+2012-05-24  Werner LEMBERG  <wl@gnu.org>
+
+	* src/roff/grog/grog.pl (process): Fix .so handling.
+
+	This does the same as the previous commit.
+
+2012-05-24  Denis M. Wilson  <dmw@oxytropis.plus.com>
+
+	* src/roff/grog/grog.sh: Fix .so handling.
+
+	See
+
+	http://lists.gnu.org/archive/html/bug-groff/2012-05/msg00000.html
+
+	for the report and the bug fix.
+
+2012-05-24  Ivan Shmakov  <oneingray@gmail.com>
+
+	Add some generic fallback characters.
+
+	* tmac/fallbacks.tmac: New file.
+	* tmac/troffrc: Include it.
+	* tmac/Makefile.sub (NORMALFILES): Include it.
+
+2012-05-20  Deri James  <deri@chuzzlewit.demon.co.uk>
+
+	* doc/groff.texinfo: Add extra info about `.asciify'.
+	Document new gropdf options -u and -s.
+
+	* src/devices/gropdf/gropdf.man: Remove references to Type 42
+	fonts, they do not work in PDFs.
+
+	Document new option -s which adds `statistics' line to end of PDF
+	file showing number of pages in document.  This has always been
+	the default behaviour (to add this line), all other software seems
+	to ignore it as intended, but `gs' sometimes complains, so the
+	default is now to omit the statistics.
+
+	Document new option -u[cmapfilename] to allow a user ToUnicode
+	CMap instead of gropdf's default.  If no `cmapfilename' given then
+	do not include any ToUnicode CMap.
+
+	* src/devices/gropdf/gropdf.pl <top>: Allow `bundled' flags on
+	command line (i.e. -de = -d -e).
+
+	Use $RT_SEP as multi path separator, not hard coded `:'.  Update
+	all users.
+
+	New flags -u and -s.  Once a custom papersize has been set as
+	\X'papersize x,y' make it sticky so all following pages use custom
+	size.  When importing pdf with \X'pdf: pdfpic ...' do not compress
+	objects which are already compressed! This caused problems with
+	PDFs created with ImageMagick, now fixed.
+
+	(IsText, PutLine, do_t): The troff `u' command can contain a
+	kerning adjustment number, this was not being handled, now fixed.
+
+	(do_c): The troff `c' command was not being handled correctly, now
+	fixed.
+	(FindChar, RemapChr, do_N): Handle fonts with more than 255 glyphs.
+	($ucmap): Define CMap ToUnicode to convert ligatures
+	(fl,fi,ff,ffl,ffi) back to individual characters, useful for
+	cut'n'paste and text searching.
+	(LoadFont): Handle it.
+	(ToPoints, GetPoints): Handle `z' unit.
+	(do_x, FixPDFColour, PutHotSpot): Allow Annotation colour to be
+	groff colour, i.e. 0-65535 *3, or #rrggbb, or #rrrrbbbbgggg.
+	(do_p):The papersize width/length in switch -p were reversed,
+	corrected.
+
+	* src/devices/gropdf/Makefile.sub (gropdf): Use $RT_SEP.
+	Use $fontpath rather than $fontdir (this ensures site-font is
+	included in searches).
+
+	* tmac/pdf.tmac (PDFBOOKMARK.VIEW, PDFHREF.VIEW, PDFPAGE.Y): Fix
+	strings.
+	(pdfbookmark): Correct handling of bookmark levels.
+	Convert \[em] to hyphen in bookmarks
+
+	Rather use -N than -T for "named" bookmarks (-T already used for
+	"tag" in pdfmark.tmac)
+
+	(.pdfclean): New macro which attempts to asciify bookmark text.
+	(.pdfpagename): New wrapper macro for \X'pdf: pagename'.
+	(.pdfswitchtopage): New wrapper macro for \X'pdf: switchtopage'.
+
+2012-03-10  Werner LEMBERG  <wl@gnu.org>
+
+	Fix compiler warnings.
+
+	* src/preproc/html/pre-html.cpp (alterDeviceTo): Avoid ambiguous
+	if-else clause.
+
+	* src/preproc/grn/main.cpp (sccsid): Comment out.
+
+	* src/roff/troff/number.cpp (parse_expr) <case '*'>: Add cast.
+
+	* src/devices/xditview/Makefile.sub (EXTRA_CFLAGS): Add `-Dlint'
+	so that unused static ID arrays don't cause a warning.
+
+	(Some) problems reported by Bjarni Ingi Gislason
+	<bjarniig@rhi.hi.is>.
+
+2012-03-05  Werner LEMBERG  <wl@gnu.org>

+	[an-old] Fix warnings.
+
+	* tmac/an-old.tmac (an-init): Insert missing braces.
+
+2012-02-26  Werner LEMBERG  <wl@gnu.org>
+
+	Update configuration files from `gnulib' and `config' repositories.
+
+	This also fixes a problem with `iconv' on Solaris 10, as reported
+	in
+
+	http://lists.gnu.org/archive/html/bug-groff/2012-02/msg00007.html
+
+	* configure.ac: Call `gl_LOCALCHARSET.
+	Call `AM_ICONV' as C++.
+
+	* config.guess, config.rpath, config.sub, install-sh, mkinstalldir:
+	Updated.
+
+	* m4/codeset.m4, m4/glib21.m4, m4/iconv.m4, m4/lib-ld.m4,
+	m4/lib-link.m4, m4/lib-prefix.m4: Updated.
+	* m4/fcntl-o.m4, m4/localcharset.m4: New files.
+
+	* Makefile.in: Updated.
+
+	* src/include/localcharset.h, src/libs/libgroff/config.charset,
+	src/libs/libgroff/localcharset.c: Updated.
+
+	* aclocal.m4, configure, src/include/config.hin: Regenerated.
+
+2012-02-20  Werner LEMBERG  <wl@gnu.org>
+
+	Update `gnulib' files.
+
+	The invocation was
+
+	gnulib-tool --add-import \
+	              --dir=src/libs/gnulib \
+	              wcwidth
+
+	Additionally, src/libs/gnulib/configure.ac was adjusted from a
+	`test' run as described in the change from 2010-12-13.
+
+	* src/libs/gnulib/*: Updated.
+
+2012-02-15  Deri James  <deri@chuzzlewit.demon.co.uk>
+
+	[gropdf] Fixes and omissions.
+
+	* src/devices/gropdf/gropdf.pl (<top>, do_u): Add facility to
+	handle track kerning (.tkf).
+
+	(do_x, do_p, do_t): If pages are reordered using `pagename' and
+	`switchtopage' keep track of outline bookmarks.
+	(do_x): Handle multiple files on gropdf command line, stitch
+	multiple groff_out files together.  In the main read loop any argc
+	values not consumed by options are taken as input files and
+	processed in order.  What prevented it working properly before is
+	the way an `x i' (initialize) record has been handled.  It now
+	processes the initialization code only in the first file.
+
+	(PutHotSpot): Allow user to control size of hotspot bounding box
+	on clickable links by setting PDFHREF.LEADING
+
+	* tmac/pdf.tmac (PDFHREF.LEADING): Adjust value.
+	(pdf*href): Pass value of PDFHREF.LEADING to gropdf.

+
+2012-02-08  Werner LEMBERG  <wl@gnu.org>

+
+	Fix handling of MAKEFLAGS variable.
+
+	* Makefile.in (MAKE_K_FLAGS): Improved definition,

+
+2012-01-03  Ingo Schwarze  <schwarze@usta.de>
+
+	Improve parallel builds.
+
+	Some hdtbl and mom examples want PostScript formatting which
+	requires the `DESC' file to be ready; however, the top-level
+	`Makefile.in' doesn't currently enforce the proper order of
+	building of `font/dev' before `contrib/hdtbl', `contrib/mom', and
+	so on.
+
+	Given that `font/dev' and the contrib examples are in different
+	child processes of the recursive make system, it doesn't seem
+	possible to solve this using clean Makefile dependencies.  We now
+	enforce the order by splitting the shell command invoking
+	recursive make in the top level `Makefile.in'.
+
+	* Makefile.in (ALLDIRS): Remove `OTHERDIRS'.
+	(dodirs): Updated.
+	(`$(TARGETS)'): Handle `OTHERDIRS' separately.
+
+2012-01-03  Kristaps Dzonsons  <kristaps@bsd.lv>
+
+	[mdoc] Add `-isoC-2011'.
+

+
+2011-08-14  Deri James  <deri@chuzzlewit.demon.co.uk>
+
+	[gropdf] More minor fixes.
+
+	* font/devpdf/Makefile.sub (MOSTLYCLEANADD): Don't attempt to
+	install 'util/BuildFoundries', only used in 'make'.
+
+	* src/devices/gropdf/gropdf.pl (<top>, GetType1): Make STDOUT and
+	any font files read to be accessed in binary rather than text mode.
+	Prevents errors when running on systems set up for UTF-8.
+
+2011-08-10  Deri James  <deri@chuzzlewit.demon.co.uk>
+
+	[gropdf] Minor updates and fixes.

+	Support alternative font file names (separated with `!').
+
+	* font/devpdf/Makefile.sub: Fixes to work with a separate build

+	Font files are now build at `make' time; this makes `test-groff'
+	work with -Tpdf.

+	* font/devpdf/util/Makefile.sub: Removed.
+
+	* Makefile.in (DEVDIRS, OTHERDIRS, EXTRADIRS): Handle devpdf

+
+2011-03-29  Christian Weisgerber  <naddy@mips.inka.de>
+
+	Fix build with non-GNU make.
+
+	* Makefile.in ($TARGETS): We must not pass `$MDEFINES' recursively
+	down to the sub-makes started in src/libs/gnulib, because that
+	directory has its own values for `$top_srcdir' etc., and
+	overriding those from the command line will cause the build to
+	fail.  Currently, `$MAKEOVERRIDES' will prevent the recursive
+	passing of those overrides with GNU make, but not with other
+	make(1) implementations.  It looks like all targets that require
+	`$MDEFINES' set them explicitly anyway, so we shouldn't need to
+	set `$MDEFINES' on the top level.
