* man/help2man: Update to help2man-1.48.5, but merging in the
latest #!/usr/bin/env change. Bruno Haible reported that it
failed a new gnulib syntax-check due to an old FSF mailing
address in https://bugs.gnu.org/73139
Run "make update-copyright" and then...
* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* man/Makefile.am $(dist_man1_MANS): Adjust sed substitution
to also remove the space after "GNU". This avoids the single
leading space on each man page title line. I'm guessing that
interfered with indexing/searching, causing "man -k diff3" to
print this: diff3 (1) - (unknown subject).
Reported by Dan Jacobon in http://bugs.gnu.org/39769.
* man/Makefile.am (dist_man1_MANS): Elide "GNU " prefix
from the generated prog+one-line-summary, so that help2man
uses the program name rather than "GNU" as the nroff "name".
Reported by Dan Jacobson in http://bugs.gnu.org/38574.
Run "make update-copyright" and then...
* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
The PATH was set incorrectly, so that the diff used by
help2man was the one from $PATH, rather than the just-built
one.
* man/Makefile.am (bin_dir): New variable, to...
(dist_man1_MANS): ...prepend ../src to PATH, not just "..".
Also, add a test to ensure that each $(bin_dir)/$$base is
executable, so this doesn't happen again.
In http://debbugs.gnu.org/21023, Rodrigo Valiña
Gutiérrez reported that diff.1 from the diffutils-3.3 tarball
contained no description of the then-new --no-dereference option.
But do ensure -- in all other circumstances -- that the man/*.1
files are rebuilt whenever the version number changes.
* configure.ac (SRC_VERSION_C): Define.
* man/Makefile.am (dist_man1_MANS): Rename from $(man1_MANS),
so that we distribute those pesky man/*.1 files.
(EXTRA_DIST): Reflect name change.
(MAINTAINERCLEANFILES): Define this, not DISTCLEANFILES,
now that these generated files are distributed.
($(dist_man1_MANS)): Depend on $(SRC_VERSION_C), so we get the
full dependency when not building from a tarball.
* 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.
* man/cmp.x: New file.
* man/diff3.x: New file.
* man/sdiff.x: New file.
* man/diff.x: Add xrefs to the other three programs, and to patch.
* man/Makefile.am (EXTRA_DIST): List new files.
(cmp.1, diff3.1, sdiff.1): Depend on each .x file.
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 ($(dist_man1_MANS)): Remove now-unnecessary sed
filter.
* README: Update references to diffutils.texi etc. here, too.
* .gitignore: Update here, too.
Suggested by Karl Berry.
* man/diff.x: New file, to add "SEE ALSO" reference to wdiff(1).
* man/Makefile.am (diff.1): Depend on diff.x.
($(dist_man1_MANS)): Tell help2man to include diff.x.
(EXTRA_DIST): Add diff.x.
