+ Fix domain handling in argp
+
+ man-db sets its default text domain to "man-db", and keeps all Gnulib's
+ strings in a separate "man-db-gnulib" domain, using 'gnulib-tool
+ --po-domain=man-db' which results in
+ -DDEFAULT_TEXT_DOMAIN=\"man-db-gnulib\". (I checked this general
+ approach with Bruno a while back and he said it was fine.)
+
+ However, Gnulib's argp implementation has three bugs which cause this
+ not to work properly:
+
+ * It hardcodes "libc" as a domain in two places. This is obviously
+ wrong in Gnulib.
+
+ * It uses argp_domain as both the domain used to translate its own
+ strings (i.e. string literals in lib/argp-*.c) and the domain used
+ to translate strings provided by the user, which normally have to
+ use gettext_noop so that they can be used as 'struct argp_option'
+ initialisers. This is dreadfully inconvenient because you have to
+ copy strings about all over the place and keep your POT file up to
+ date as the argp implementation changes. If argp is in libc then
+ this is obviously impossible.
+
+ Instead, argp should use DEFAULT_TEXT_DOMAIN to translate its own
+ string literals (falling back to the default program domain if that
+ is not set), and should reserve argp_domain for translating strings
+ that appear in that argp structure.
+
+ * In a number of places, argp uses the domain of the root argp
+ structure when translating text from a child argp structure. This is
+ the direct cause of Robert's bug, because the standard --help and
+ --version options are implemented as a child argp structure with its
+ own domain.
+
+ My patch changes this to use argp_domain from the child instead.
+ However, on reflection, I'm not certain that this is correct;
+ arguably it needs to walk up the tree until it finds a domain to
+ use. This depends on whether you think that argp_domain == NULL
+ means "use default program domain" or "use same domain as parent
+ argp structure".
