auto-revert-timer only if it is non-nil. This avoids errors
on first invocation of Auto-Revert mode.

environments provided by "listings" and "breqn" packages and the
macro "\ctable" from the package of the same name.
Update docstring.
More specifically, don't add a useless '(fn)' to the docstring for
functions which take no arguments.
This should fix the 'No docstring slot for pcase--make-docstring'
warning during bootstrap.
(cursor-sensor--detect): Also consult overlay properties when checking
to see if we just moved inside the same "element" as opposed to
changing from one to another of the same type.
* lisp/textmodes/ispell.el (ispell-set-spellchecker-params):
Set ispell-last-program-name only at the end, so as to produce
useful diagnostics when Hunspell dictionaries are not found.

* doc/lispref/searching.texi (Regular Expression Functions):
* lisp/emacs-lisp/regexp-opt.el (regexp-opt):
Rename newly added `noreorder' argument to `keep-order', to avoid a
negative in the name. Suggested by Phil Sainty (Bug#34641).
* lisp/window.el (window-combinations): New optional argument
IGNORE-FIXED.
(window--combination-resizable): New function.
(split-window): Fix handling of 'window-combination-resize'
in the presence of fixed-size windows.
It is not relevant since Gnus stopped being distributed separately.
* etc/GNUS-NEWS: Remove this generated file.
* etc/NEWS.26: Relocate an entry mistakenly added to GNUS-NEWS.
* doc/misc/gnus-coding.texi (Gnus Maintenance Guide):
No longer mention GNUS-NEWS.
* doc/misc/gnus-news.el: Remove.
* doc/misc/gnus-news.texi: Update a comment.
* lisp/Makefile.in (update-gnus-news): Remove this phony target.
* lisp/progmodes/verilog-mode.el (verilog-read-decls): Fix AUTO vectors with
double brackets, msg2839.
(verilog-read-auto-template-middle): Fix AUTO_TEMPLATE with regexp
capture group reference, but1379. Reported by David Rogoff.
* doc/lispref/frames.texi (Buffer Parameters): Describe how to
make a minibuffer-only child frame.
(Child Frames): Describe how minbuffer child frames are
deleted.
* src/frame.c (delete_frame): Handle deletion of minibuffer
child frames (Bug#33498). In the course, fix reassigning of
'default-minibuffer-frame' with minibuffer-only frames.
* lisp/frame.el (frame-notice-user-settings): Handle creation of
initial minibuffer-only child frame.
(make-frame): Handle creation of frame with a minibuffer-only
child frame.
This change was discussed in Bug#32991.
* admin/gitmerge.el (gitmerge-resolve): Bind 'diff-refine'
instead of 'diff-auto-refine-mode' to nil.
* doc/emacs/files.texi (Diff Mode): Explain 'diff-refine'
instead of 'diff-auto-refine-mode' in the documentation of
'diff-hunk-next' and 'diff-hunk-prev'. Mention in the
documentation of 'diff-refine-hunk' that refining is already
done by default.
* etc/NEWS (Diff mode): Explain renamed 'diff-refine' variable
and mention deprecation and disabling of
'diff-auto-refine-mode'.
* lisp/vc/diff-mode.el (diff-font-lock-refine): Rename to
'diff-refine' and allow choices nil, 'font-lock' and 'navigation'.
(diff-auto-refine-mode): Disable it by default, make it
obsolete and make it set 'diff-refine' appropriately to keep
backward compatibility.
(diff-hunk-next, diff-hunk-prev): Adapt to rename of
diff-auto-refine-mode and ensure that refining only happens
when calling these commands interactively.
(diff--font-lock-refined): Adapt to rename of
diff-font-lock-refine.
* lisp/vc/smerge-mode.el (smerge-next, smerge-prev): Check
that 'diff-refine' is set instead of checking
'diff-auto-refine-mode' when deciding whether to refine a
conflict.
* lisp/dnd.el (dnd-get-local-file-uri): Always return nil on
MS-Windows, as this method cannot possibly work there: URIs
that begin with the local system's name are UNCs, where the
//SERVER part cannot be removed. (Bug#34675)
When regexp-opt is called with an empty list of strings, return a regexp
that doesn't match anything instead of the empty string (Bug#20307).
* doc/lispref/searching.texi (Regular Expression Functions):
* etc/NEWS:
Document the new behaviour.
* lisp/emacs-lisp/regexp-opt.el (regexp-opt):
Return a never-match regexp for empty inputs.
The rx `or' form may reorder its arguments in an unpredictable way,
contrary to user expectation, since it sometimes uses `regexp-opt'.
Add a NOREORDER option to `regexp-opt' for preventing it from
producing a reordered regexp (Bug#34641).
* doc/lispref/searching.texi (Regular Expression Functions):
* etc/NEWS (Lisp Changes in Emacs 27.1):
Describe the new regexp-opt NOREORDER argument.
* lisp/emacs-lisp/regexp-opt.el (regexp-opt): Add NOREORDER.
Make no attempt at regexp improvement if the set of strings contains
a prefix of another string.
(regexp-opt--contains-prefix): New.
* lisp/emacs-lisp/rx.el (rx-or): Call regexp-opt with NOREORDER.
* test/lisp/emacs-lisp/rx-tests.el: Test rx `or' form match order.
* doc/lispref/nonascii.texi (Default Coding Systems): Clarify
that the functions in 'auto-coding-functions' are called both
for decoding and for encoding.
* lisp/international/mule.el (auto-coding-functions): Doc fix.
* lisp/international/mule.el (sgml-xml-auto-coding-function)
(sgml-html-meta-auto-coding-function): Don't use
'buffer-file-coding-system' if the buffer is unibyte.
