* build-aux/git-hooks/commit-msg: Set LC_ALL=C, before running Awk
in unibyte environments. (Suggested by Paul Eggert
<eggert@cs.ucla.edu>.) Use a more accurate approximation to
[:print:], based on UTF-8 sequences of the unprintable characters.

* build-aux/git-hooks/commit-msg (cent_sign_utf8_format)
(cent_sign, print_at_sign, at_sign): Revert previous change.
(print_at_sign): Prepend "BEGIN".
(at_sign): Redirect from /dev/null to be safer with pre-POSIX awk.
* .gitignore: Add 'ChangeLog'.
* build-aux/gitlog-to-changelog: New file, from Gnulib.
* build-aux/gitlog-to-emacslog: New file.
* CONTRIBUTE: Document the revised workflow.
* Makefile.in (clean): Remove *.tmp and etc/*.tmp*
instead of just special cases.
(CHANGELOG_HISTORY_INDEX_MAX, CHANGELOG_N, gen_origin): New vars.
(ChangeLog, unchanged-history-files, change-history)
(change-history-commit): New rules.
* admin/admin.el (make-manuals-dist--1):
Don't worry about doc/ChangeLog.
* admin/authors.el: Add a FIXME.
* admin/make-tarball.txt:
* lisp/calendar/icalendar.el:
* lisp/gnus/deuglify.el:
* lisp/obsolete/gulp.el:
* lwlib/README:
Adjust to renamed ChangeLog history files.
* admin/merge-gnulib (GNULIB_MODULES): Add gitlog-to-changelog.
* admin/notes/repo: Call it 'master' a la Git, not 'trunk' a la Bzr.
Remove obsolete discussion of merging ChangeLog files.
New section "Maintaining ChangeLog history".
* build-aux/git-hooks/pre-commit:
Reject attempts to commit files named 'ChangeLog'.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* make-dist: Make and distribute top-level ChangeLog if there's a
.git directory. Distribute the new ChangeLog history files
instead of scattered ChangeLog files. Distribute the new files
gitlog-to-changelog and gitlog-to-emacslog.
Fixes: bug#19113
Problem reported by Ted Zlatanov in:
http://lists.gnu.org/archive/html/emacs-devel/2014-12/msg01093.html
* build-aux/git-hooks/commit-msg (space, non_space, non_print):
New vars. Use them as approximations to POSIX bracket expressions,
on implementations like mawk that do not support POSIX regexps.
Problem reported by Michal Nazarewicz in Bug#19337.
* build-aux/git-hooks/commit-msg: Add "commit message" to
diagnostics. Distinguish better between tabs and other
unprintable chars in diagnostics. Don't complain if a prefix
"fixup! " or "squash! " makes a summary line too long.
This fixes a bug reported by Jan Djärv in:
http://lists.gnu.org/archive/html/emacs-devel/2014-12/msg00704.html
along with some other issues I noticed while testing with FreeBSD.
* build-aux/git-hooks/commit-msg: Prefer gawk if available.
Prefer en_US.UTF-8 to en_US.utf8, as it's more portable.
Work around bug in FreeBSD 9 awk, where /[[:cntrl:]]/ matches
ordinary text characters.
Be less tricky about quoting "'" in a shell script.
* autogen.sh: Install Git hooks, if using Git.
* build-aux/git-hooks/commit-msg, build-aux/git-hooks/pre-commit:
New files, which are Git hooks that check for portable file names, and
do some simple checks for commit message format.
