This prevents emacs-lisp-mode-hook from being run everytime an
autoload file is generated, which can account for a fraction of

on a broken MS-Windows shell.  Reported by Eli Zaretskii in:

Minor quoting etc. fixes to misc manuals

Fix some minor quoting and spacing issues.  Distinguish more
clearly among grave accent and apostrophe (which are ASCII) and
single quote (which is not).  Prefer the standard terms
"apostrophe" and "grave accent" to alternative names that can be
confusing.  Use apostrophes to single-quote ASCII text.
* doc/misc/remember.texi: Spell the mystic's pseudonym in UTF-8
rather than approximating it in ASCII with grave accent.

Have commit-msg report commit failure

* build-aux/git-hooks/commit-msg: If the commit is aborted,

by Eli Zaretskii in:

* doc/lispref/commands.texi, doc/lispref/control.texi:

* src/window.c (Frecenter): Use the same code for GUI and TTY
frames alike; use vmotion only for "initial" frames.  This is
because vmotion doesn't support visual-line-mode.  Rewrite the
'iarg >= 0' case to use move_it_* functions instead of using
vmotion, for the same reason.  Fix the clipping of the argument
value to support scroll-margin in all cases and avoid unwarranted
recentering.  Reported by Milan Stanojević <milanst@gmail.com> in
