This fixes bug#72695.
* lisp/progmodes/cc-align.el (c-lineup-topmost-intro-cont): Do
not indent further a line following a closing brace of a
requires clause.
* lisp/progmodes/cc-engine.el (c-forward-keyword-clause):
Separate the handling of "any-paren-kwds" into
"type-paren-kwds" and "nontype-paren-kwds", simplifying the
handling of the latter.
(c-forward-primary-expression): Recognize (...) followed by {
as a primary expression.
(c-looking-at-or-maybe-in-bracelist): No longer recognize an
enum list as a brace list. Remove the handling of enum lists.
(c-looking-at-c++-lambda-expression)
(c-backward-over-lambda-expression): New functions.
(c-c++-vsemi-p): Don't recognize the end of requires clauses as
virtual semicolons.
(c-guess-basic-syntax): CASE 5U - new cond arm to recognize
being after a requires clause. These lines now get syntax
topmost-intro-cont rather than topmost-intro, and their anchor
positions are now on the topmost-intro line rather than the
previous topmost-intro-cont.
Throughout the file: simplify handling of
c-fun-name-substitute-key, where there is no need to check for
a following _ character, and introduce c-requires-clause-key
for greater accuracy in parsing, even though both of these are
just "requires".
* lisp/progmodes/cc-fonts.el (c-get-fontification-context):
Tidy up the handling of c-fun-name-substitue-key, as in
cc-engine.el.
* lisp/progmodes/cc-langs.el (c-lambda-spec-kwds)
(c-lambda-spec-key): New lang vars.
(c-fun-name-substitute-key): Now an adorned expression.
(c-requires-clause-kwds, c-requires-clause-key): New lang vars.
If point was after a file or hunk header, the diff-file-prev and
diff-hunk-prev commands would move to the start of that header.
But if point was *within* the header, they would not move, and
would report "No previous file" or "No previous hunk". This
differs from the behavior of most other movement commands,
e.g. backward-sexp or backward-sentence.
This commit fixes diff-file-prev and diff-hunk-prev, as well as
other easy-mmode-define-navigation BASE-prev commands. Now
these commands move to the start of the containing "thing" just
like other movement commands.
* lisp/emacs-lisp/easy-mmode.el (easy-mmode--prev):
Move to start of current match first. (bug#73172)
* etc/NEWS: Document the behavior change.
The functions defined by easy-mmode-define-navigation are useful
even if the easy-mmode-define-navigation macro is not used.
Let's take a step towards exposing them by moving them out as
helpers.
This also makes the macro much easier to modify and work on.
* lisp/emacs-lisp/easy-mmode.el (easy-mmode--prev)
(easy-mmode--next): Add (bug#73172).
(easy-mmode-define-navigation): Use easy-mmode--prev and
easy-mmode--next.
* lisp/vc/diff-mode.el (diff-revert-and-kill-hunk): New
command (bug#73407).
(diff-ask-before-revert-and-kill-hunk): New user option.
(diff-apply-buffer): New optional BEG, END and REVERSE
arguments. Return nil if buffers were saved, or the number of
failed applications.
(diff-mode-map): Bind the new command to C-c M-r.
(diff-mode-menu): New entry for the new command.
* doc/emacs/files.texi (Diff Mode):
* etc/NEWS: Document the change.
Add '(car pattern)' as the LIGHTER argument of 'highlight-regexp'.
This fixes the case when in a file buffer with fundamental-mode:
`C-s M-s ' the M-s h r RET`, revert the buffer with 'C-x x g',
get the prompt for unhighlight with 'M-s h u'. This showed
a raw regexp instead of the human-readable lighter (bug#57534).
This will allow enums to be indented as in the GNU coding
standards without affecting brace lists.

(c-lineup-arglist-intro-after-paren)
(c-lineup-arglist-close-under-paren)
(c-lineup-whitesmith-in-block)

indicate they can be used for enum-* syntactic symbols too.
* lisp/progmodes/cc-engine.el (c-looking-at-decl-block)
(c-backward-typed-enum-colon, c-backward-over-enum-header):
Rename c-after-brace-list-key to c-after-enum-list-key and
c-brace-list-key to c-enum-list-key.
(c-at-enum-brace): New function.
(c-inside-bracelist-p): Don't check for enums any more.

use enum-* syntactic symbols rather than brace-list-* ones
where appropriate.
(c-used-syntactic-symbols): New dynamic variable.
(c-evaluate-offset): Add handling for a different syntactic
symbol as the cdr of a c-offsets-alist element.
* lisp/progmodes/cc-fonts.el (c-get-fontification-context):
Add a call to c-at-enum-brace since c-inside-bracelist-p no
longer handles enums.
(c-font-lock-enum-body, c-font-lock-enum-tail): Condense calls
to c-backward-over-enum-header to c-at-enum-brace.
(c-basic-matchers-after): Replace a c-brace-list-decl-kwds with
c-enum-list-kwds.
* lisp/progmodes/cc-langs.el (c-enum-list-kwds)
(c-enum-list-key): New names for c-brace-list-decl-kwds and
c-brace-list-key.
(c-after-enum-list-kwds, c-after-enum-list-key): New names for
c-after-brace-list-decl-kwds and c-after-brace-list-key.
(c-enum-list-key, c-after-enum-list-key): Add code to
use a value of an old name, should a derived mode still use
that.

syntactic symbol" into an error message text.
* lisp/progmodes/cc-vars.el (c-valid-offset): Allow for a
syntactic symbol as the parameter.
(c-offsets-alist): Add new syntactic symbols enum-open,
enum-close, enum-intro, and enum-entry.
* doc/misc/cc-mode.texi (Syntactic Symbols): Add a note that
anchor points are briefly documented in cc-vars.el. Correct
the suffix "-block-intro" to "-intro". Remove "an enum or"
from the descriptions of the brace-list-* syntactic symbols.
Add in new descriptions for the enum-* syntactic symbols.
(Brace List Symbols): Remove references to enums. Add a note
that enums are no longer brace-lists.
(Enum Symbols): A new subsection documenting the new enum-*
syntactic symbols.
(c-offsets-alist): Document the new possibility, syntactic
symbol, for the cdr of an alist entry.
(Brace/Paren Line-Up, List Line-Up): Note that the new enum
syntactic symbols can be handled by these lineup functions.
The current behavior is inconsistent with that of the normal backquote
macro, so to avoid surprises, warn about the use of nested backquotes.
* lisp/emacs-lisp/pcase.el (pcase--expand-\`): Warn about nested backquotes.
* lisp/emacs-lisp/testcover.el (testcover-analyze-coverage)
(testcover-analyze-coverage-wrapped-form): Avoid nested backquotes
Pass all dropped files to 'dnd-handle-multiple-urls' in
one call instead on doing multiple calls (Bug#73258).
* lisp/term/w32-win.el (w32-dropped-file-to-url): New function to
convert file name to a url for dnd.
(w32-handle-dropped-file): Changed to use 'w32-dropped-file-to-url'.
(w32-drag-n-drop): Changed to pass all files to
'dnd-handle-multiple-urls'/
1: Fix the typing of a space on the { line in an enum
specification which is the first item in a buffer. This
defontified the enum's identifiers.
2: Fix the typing of a space on the line of the enum's last
identifier. This defontified that identifier for
jit-lock-context-time.
* lisp/progmodes/cc-engine.el (c-forward-declarator): Cease
rejecting the identifier if there are no further tokens before
LIMIT.
* lisp/progmodes/cc-mode.el (c-fl-decl-start): Accept a
backward search as succeeding if it hits point-min.
* lisp/midnight.el (midnight-mode): Call 'midnight-delay-set' again
when the mode is activated.
(midnight-delay-set): Only start the timer if the mode is turned
on. (Bug#73291)
* etc/NEWS: Document the change in behaviour.
* lisp/progmodes/python.el
(python-font-lock-keywords-maximum-decoration)
(python--treesit-exceptions): Add all built-in exceptions in Python 3.13
as keywords. Missing from the list was "BaseExceptionGroup",
"EncodingWarning", "ModuleNotFoundError", and "PythonFinalizationError".
