Subject: [PATCH 1/4] doc: rename diff.texi to diffutils.texi

This makes the .texi basename the same as the package name,
which is consistent with most other GNU packages.
* doc/diffutils.texi: Rename from...
* doc/diff.texi: ...removed.
* doc/Makefile.am (info_TEXINFOS): Reflect name change.
(diffutils_TEXINFOS): Likewise.
* cfg.mk (gendocs_options_): Remove this customization.  It is no
longer needed, now that the .texi name matches that of the package.
* man/Makefile.am ($(dist_man1_MANS)): Remove now-unnecessary sed
filter.
* README: Update references to diffutils.texi etc. here, too.
* .gitignore: Update here, too.
Suggested by Karl Berry.

Subject: [PATCH 3/4] build: ccache works better without embedded version
 strings

* src/Makefile.am: Generate version.c and version.h and put the
new symbol in a tiny library to be used by each program.
(LDADD): Add the new library.
* src/cmp.c (main): Use Version, not PACKAGE_VERSION, so the .o
file does not change with each commit-derived version increment.
* src/diff.c (main): Likewise.
* src/diff3.c (main): Likewise.
* src/sdiff.c (main): Likewise.
* src/system.h: Include "version.h".
* .gitignore: Add version.[ch]

Subject: [PATCH 4/4] doc: do not distribute generated man/*.1 man files

* man/help2man: New file.
* man/Makefile.am: Use $(srcdir)/help2man.
Convert $(dist_man1_MANS) to $(man1_MANS), to tell automake
not to distribute the generated man/*.1 files.  Now they're
generated at build-from-tarball time.
($(man1_MANS)): Depend on version.c, so that man pages are
regenerated whenever the version string changes.
