* lisp/mh-e/mh-search.el (mh-index-new-folder)
* lisp/mh-e/mh-utils.el (mh-prompt-for-folder):
Check for existence of 'speedbar-buffer' rather than
'mh-speed-folder-map'. The latter can exist if
'mh-speed' has only been loaded but not displayed.
(cherry picked from commit e6a2901b1b)
This simplification is symmetrical to 01fb898420.
* src/editfns.c: (Finternal__labeled_widen): Add a call to
'Fwiden', and rename from 'internal--unlabel-restriction'.
(unwind_labeled_narrow_to_region): Use the renamed function, and
remove the call to 'Fwiden'.
(syms_of_editfns): Rename the symbol.
* lisp/subr.el (internal--without-restriction): Use the renamed
function.
(cherry picked from commit 9e9e11648d)
* src/editfns.c (labeled_narrow_to_region): Record point before,
instead of after, calling narrow-to-region; otherwise point may
already have been changed. Fixes bug#66764.
* doc/lispintro/emacs-lisp-intro.texi (How let Binds Variables):
Fix cross-reference. (Bug#68428)
* test/lisp/info-xref-tests.el (info-xref-test-write-file): Fix
test on MS-Windows when run from MSYS Bash.
* doc/emacs/buffers.texi (Misc Buffer): Add @kindex for 'C-x x r',
'C-x x u', 'C-x x i'.
* doc/emacs/display.texi (Line Truncation): Add @kindex for 'C-x x t'.
* doc/emacs/files.texi (Reverting): Add @kindex for 'C-x x g'.
* doc/emacs/windows.texi (Change Window): Use new keybinding 'C-x w 0'
instead of 'M-x delete-windows-on'.
* doc/misc/info.texi (Create Info buffer): Add @kindex for 'C-x x n'.
It looks like there are actually three kinds of no-op functions.
* doc/lispref/functions.texi (Calling Functions): Fix count and
plural of no-op functions.

(custom-icon-state-set-and-redraw, custom-icon-reset-standard)
(custom-icon-mark-to-reset-standard): New functions.
(custom-icon, custom-icon-extended-menu): Register and add them to the
menu. (Bug#66947)
* lisp/emacs-lisp/package.el (package-menu--version-predicate): Ignore
any errors raised by 'version-to-list', thus falling back to the
default version list. (Bug#68317)
(cherry picked from commit eb913c7501)
* doc/lispintro/emacs-lisp-intro.texi (Prevent confusion): Rework the
explanation to discuss how things work under lexical binding.
(How let Binds Variables): Describe the differences between lexical
and dynamic binding (including how to configure it).
(defvar): Mention that 'defvar' declares variables as always
dynamically-bound (bug#66756).
* lisp/mail/rmailsum.el (rmail-summary-by-thread): Call
'rmail-new-summary' from the original buffer, not from
'rmail-buffer' to avoid failing the logic in 'rmail-new-summary'
that decides whether to pop up a new window. Reported by Andrea
Monaco <andrea.monaco@autistici.org>.
* lisp/emacs-lisp/icons.el (icons--create): Handle the case when
ICON is a file that doesn't exists or is unreadable. Suggested by
David Ponce <da_vid@orange.fr>. (Bug#66846)
* doc/lispref/buffers.texi (Buffer List):
* doc/lispref/windows.texi (Choosing Window): Add caveats for
calling 'buffer-match-p' too early, when CONDITION is
'derived-mode' or 'major-mode'. (Bug#68081)
When 'isearch-wrap-pause' is 'no' or 'no-ding', let-bind 'isearch-cmds'
to avoid changing it by 'isearch-push-state' in 'isearch-repeat',
so that a later DEL (isearch-delete-char) doesn't stop at the
intermediate failing state (bug#68158).
