Mostly this just changes ` to ' in static text.  Some exceptions:
* INSTALL.REPO: Use curved quotes, as the diagnostic in question
typically does that now.
* admin/quick-install-emacs (TRY, top level):
Use straight quoting in diagnostics.
* src/README: Fix working-directory confusion.

From a suggestion by Mitchel Humpherys in:
http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg00421.html
* admin/notes/git-workflow (Sending patches): New section.

* lisp/term/x-win.el: Convert to UTF-8.  This doesn't affect
runtime behavior, and the file is multilingual so compile-time
appearance shouldn't be an issue.
* admin/notes/unicode: Document this.

Update admin/notes/unicode, along with coding system cookies in
other files, so that the two match each other better.
* admin/notes/unicode: lisp/language/ethio-util.el and
lisp/language/ethiopic.el also use utf-8-emacs.
* admin/notes/hydra, doc/misc/dbus.texi, doc/misc/org.texi:
* doc/misc/remember.texi, etc/refcards/cs-dired-ref.tex:
* etc/refcards/cs-refcard.tex, etc/refcards/cs-survival.tex:
* etc/refcards/sk-dired-ref.tex, etc/refcards/sk-refcard.tex:
* etc/refcards/sk-survival.tex:
Add "coding: utf-8" so that this file is not mishandled in a
Latin-1 or Big-5 locale.
* lisp/international/robin.el, lisp/org/ox-ascii.el:
Specify utf-8, not utf-8-emacs, as these are plain UTF-8 files.
* lisp/language/ethio-util.el: Fix trailer.

* .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.
