-.\" === Define alternating font macros. ===
-.\"
-.\" Implementation notes:
-.\"
-.\" We always emit a dummy character \& before the first argument.  This
-.\" is necessary only when the calling man page is in compatibility
-.\" mode; it works around the surprising AT&T semantics of \f escapes at
-.\" the beginning of an input line.  See "Implementation differences" in
-.\" groff_diff(7) or the groff Texinfo manual.
-.\"
-.\" The italic correction escapes can be visually confusing.  We apply
-.\" the following rules, always on the same input line.
-.\"   (1) Before any italic argument, emit a left italic correction \,
-.\"       before switching to the italic style.
-.\"   (2) After any italic argument, emit an italic correction \/
-.\"       before switching to another style.
-.\" It is true that these macros cannot know what style is used in the
-.\" input stream before or after they are called.  We can make
-.\" assumptions based on pragmatics.  In most cases, the caller will not
-.\" precede a call to one of these macros with \c, or add it to the
-.\" final argument given to one of these calls; when \c is absent, what
-.\" is adjacent must be a word space or output line boundary, so italic
-.\" corrections don't matter.  If \c _is_ used by the caller, we can
-.\" assume that the adjacent glyphs before an IB or IR call, or the
-.\" following ones after a BI or RI call, will not be italic (and thus
-.\" will benefit from the italic correction we provide); otherwise the
-.\" caller would simply have added the relevant characters to the
-.\" arguments of the macro call.
