* lisp/simple.el (next-error-message-highlight): This function is
called directly, so clean up the code a bit (bug#32676).
(next-error-found): Pass in the error buffer.
* lisp/gnus/gnus-fun.el (gnus-convert-face-to-png): Do it.
* lisp/gnus/gnus-util.el (gnus-base64-repad): Allow not checking
anything, but just repadding.
Fix a few places I missed, where we incorrectly used lexical scoping on a var
that needed dynamic scoping.
These were detected thanks to a bit of footwork by Mattias Engdegård!
* lisp/calc/calc-ext.el (math-read-big-lines): Declare as dynbound.
(math-read-big-bigp): Bind it inside a `let`.
* lisp/calc/calc-graph.el (math-arglist): Declare as dynbound.
* lisp/calc/calc-map.el (math-arglist): Declare as dynbound.
* lisp/calc/calc-misc.el (math-trunc-prec): Declare as dynbound.
(math-trunc): Bind it inside a `let`.
(math-floor-prec): Declare as dynbound.
(math-floor): Bind it inside a `let`.
* lisp/calc/calc-nlfit.el (calc-curve-varnames, calc-curve-coefnames):
Declare as dynbound.
* lisp/calc/calc-sel.el (math-comp-sel-tag): Declare as dynbound.
* lisp/calc/calcsel2.el (calc-sel-reselect): Declare as dynbound.
* lisp/replace.el (query-replace-highlight-submatches): New defcustom.
(replace-submatches-overlays): New variable.
(replace-highlight): Use query-replace-highlight-submatches.
(replace-dehighlight): Use query-replace-highlight-submatches.
* doc/emacs/search.texi (Query Replace):
Add documentation for query-replace-highlight-submatches.
Suggested by Drew Adams <drew.adams@oracle.com> in bug#43702.
* lisp/progmodes/grep.el (grep-expand-template): Add new arg 'more-opts'.
(grep-use-directories-skip): New variable.
(lgrep): Set 'grep-use-directories-skip' to the result of 'grep-probe'.
Use "--directories=skip" when 'grep-use-directories-skip' is t.
* lisp/simple.el (next-error-message-highlight):
(next-error-message): New faces (bug#32676).
(next-error--message-highlight-overlay): New internal variable.
(next-error-message-highlight): New function.
(next-error-found): Call the function.
* doc/emacs/indent.texi (Indent Convenience): Mention it.
* doc/lispref/text.texi (Mode-Specific Indent): Document it.
* lisp/indent.el (tab-first-completion): New variable (bug#34787).
(indent-for-tab-command): Use it.
* lisp/dired-x.el (dired-x-guess-filename-at-point): Rename (bug#43961).
(dired-filename-at-point): Made into an obsolete alias, since the name
can be confused with the unrelated dired-file-name-at-point function.
* src/emacs.c (main): Mark the return from strerror as a constant,
since it shouldn't be changed (bug#43982).
* lib-src/movemail.c (pfatal_and_delete): Ditto.
Copyright-paperwork-exempt: yes
* lisp/emacs-lisp/package.el (package-install-button-action)
(package-delete-button-action): Run describe-package instead of
revert-buffer in order to use newer package-desc (bug#43983).
* lisp/gnus/nnimap.el (nnimap-parse-flags):
Remove old hack that deletes MODSEQ entries in the buffer, as
Emacs now has bignums and so won't misparse MODSEQs (Bug#38938).
* doc/lispref/numbers.texi (Comparison of Numbers):
Copy some useful text from eql help string.
* src/fns.c (Feql): In doc string, say that eql also compares
integers by value.
* lisp/outline.el (outline-mode-map): Fix wording of a comment.
* doc/emacs/text.texi (Outline Visibility): Fix wording and markup
of a recently added paragraph. Improve indexing.
* etc/NEWS: Fix whitespace of a recently added entry.
Setting the word size ("b w") to 0 removes the word size clipping for
all bit operations (effectively as if a word size of -∞ had been set).
Rotation is disallowed; logical and arithmetic shifts behave
identically.
After a suggestion by Vincent Belaïche.
* lisp/calc/calc-bin.el (calc-word-size, math-binary-arg)
(math-binary-modulo-args, calcFunc-lsh, calcFunc-ash, calcFunc-rot)
(math-clip, math-format-twos-complement): Allow a word size of 0,
meaning -∞.
* test/lisp/calc/calc-tests.el
(calc-tests--not, calc-tests--and, calc-tests--or, calc-tests--xor)
(calc-tests--diff): New functions.
(calc-tests--clip, calc-tests--rot, calc-shift-binary): Extend to
cover word size 0.
(calc-bit-ops): New test.
* doc/misc/calc.texi (Binary Functions): Update manual.
* etc/NEWS: Announce the change.
Make the '/' precedence higher than that of '+' and '-' again,
partially reverting fda9b316f8 (bug#43902).
* lisp/calc/calc-lang.el (tex): Change precedence of '/'.
* test/lisp/calc/calc-tests.el (calc-latex-input): New test.
* doc/lispref/internals.texi (Module Values): Document
make_unibyte_string (bug#34873).
* src/emacs-module.c (module_make_unibyte_string): New function.
(initialize_environment): Export it.
* src/module-env-25.h: Define it.
* test/data/emacs-module/mod-test.c (Fmod_test_return_unibyte):
Test it.
* test/src/emacs-module-tests.el (module/unibyte): Test it.
* etc/emacs.service (ExecStop): Partially revert previous patch
for bug#37847, since: "This appears to break packages that rely on
`invocation-name' to be executable."
* lisp/outline.el (outline--cycle-state, outline-has-subheading-p)
(outline-cycle, outline-cycle-buffer): New functions.
(outline-mode-map): Add key bindings for the two new commands.
(outline--cycle-buffer-state): New variable.
* doc/emacs/text.text (Outline Visibility): Add 'outline-cycle' and
'outline-cycle-buffer'.
* etc/NEWS (Outline): Record the change (bug#41130).
* lisp/subr.el (read-char-choice): Use `read-char-from-minibuffer'
here (bug#42708) so that we're not as modal (and users can copy
the help buffer, if they should so want).
* lisp/calendar/diary-lib.el (diary-fancy-display): Insert the
heading with the correct face, so that it doesn't have to be
re-matched later (which is generally impossible) (bug#13072).
(diary-fancy-date-pattern, diary-fancy-date-matcher): Make obsolete.
(diary-fancy-font-lock-keywords): Don't use.
(diary-fancy-font-lock-fontify-region-function): Don't use.
* lisp/cus-edit.el (custom-save-variables, custom-save-faces): These
functions sort a list, not buffer text, so they don't need
to use sort-fold-case at all. Remove the let-binding for
sort-fold-case (bug#43919).
* lisp/faces.el (header-line-highlight): Inherit from
mode-line-highlight instead of highlight (bug#43926). This is
consistent with header-line inheriting from mode-line.
* doc/man/ebrowse.1:
* doc/man/emacs.1.in:
* doc/man/emacsclient.1:
* doc/man/etags.1: Update date to match last significant change. Set
file local variable time-stamp-pattern. Fix title line to match the
recommendations in "man man-pages".
Ref: https://lists.gnu.org/r/emacs-devel/2020-09/msg01002.html
Also, use lexical-scoping. Remove redundant `:group` args.
(proced-process-alist, proced-header-line): Use `defvar-local`
(proced-header-line): Put :align-to on spaces to improve result with
variable-pitch header-line face.
(proced-filter, proced-format): Use a closure instead of `(lambda ...).
(hexl-ascii-region): Don't inherit from the `header-line`.
(hexl-font-lock-keywords): Fix text alignment.
(hexl-mode): Set `font-lock-extra-managed-props` accordingly.
Fix mistakes made when removing Cocoa code from nsfont.m.
* src/nsfont.m (nsfont_draw): Remove spurious #ifdef.
(ns_uni_to_glyphs): The #if/#endif was removed from this code, but the
code itself not removed. Remove it now.
