* lisp/emacs-lisp/checkdoc.el (checkdoc-recursive-edit): Use command
substitution.
(checkdoc--help-buffer): New variable. Use it instead of hard-coded
string.
* lisp/help-fns.el (help-fns--analyze-function): Use it.
* lisp/help-fns.el (help-enable-symbol-autoload): New user option.
* doc/emacs/help.texi (Name Help): Document it.
* lisp/cedet/pulse.el (pulse-momentary-highlight-one-line): Make
POINT optional (bug#50642) so that the function can be used more
easily from some hook functions.
Clarify things which are only relevant to 'global-so-long-mode', and
not when the 'so-long' command, or one of its actions, is invoked
directly.
Use the new "customization group" hyperlink syntax.
Only quote 'so-long' as a symbol when it specifically refers to the
command (or will otherwise generate a hyperlink which is appropriate
to the context). When referring to the library more generally, leave
it unquoted.
Changes from commit 63f419f133 are
reverted or improved.
* lisp/emacs-lisp/generator.el (iter-defun):
* lisp/emacs-lisp/comp.el (comp-clean-up-stale-eln):
* lisp/emacs-lisp/bytecomp.el (byte-compile-lapcode):
* lisp/emacs-lisp/autoload.el (autoload-insert-section-header):
Include description of arguments in the doc string's first line.
`xref-find-references` was unable to find symbols like
`backquote-list*-macro`.
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-grep--quote-extended): New function.
(semantic-symref-perform-search): Call it.
* src/keymap.c (syms_of_keymap)
<describe-bindings-check-shadowing-in-ranges>: New variable.
(describe_vector): Check shadowing of consecutive keys only if
'describe-bindings-check-shadowing-in-ranges' is non-nil. Remove
redundant second loop when VECTOR is a char-table. Improve
comments. Patch by Stefan Kangas <stefan@marxist.se>. (Bug#45379)
* test/src/keymap-tests.el
(help--describe-vector/bug-9293-one-shadowed-in-range): Adapt the
test case for the new variable.
* lisp/emacs-lisp/checkdoc.el (checkdoc-this-string-valid-engine):
Search for the modifier key "s-", but not the modifier key "A-".
The latter is very uncommon and leads to false positives.
* src/fileio.c (expand-file-name): Check for null bytes for both
NAME and DEFAULT-DIRECTORY arguments. Also check for null bytes
in buffer-local default-directory, assuming it is used.
* src/coding.c (encode_file_name): Use CHECK_STRING_NULL_BYTES.
* src/lisp.h (CHECK_STRING_NULL_BYTES): Add function for checking
for null bytes in Lisp strings.
* test/src/fileio-tests.el (fileio-test--expand-file-name-null-bytes):
Add test for new changes to expand-file-name.
* etc/NEWS: Announce changes.
* lisp/emacs-lisp/checkdoc.el (checkdoc-message-text-engine):
Change 'y-or-n-p' check to accept prompt ending with both "? " or "?",
that is, it no longer needs the space. (Bug#50621)
(checkdoc--fix-y-or-n-p): New helper function.
* test/lisp/emacs-lisp/checkdoc-tests.el (checkdoc-tests-fix-y-or-n-p)
(checkdoc-tests-fix-y-or-n-p/no-change)
(checkdoc-tests-fix-y-or-n-p/with-space): New tests.
* lisp/international/fontset.el (setup-default-fontset): Move the
fontset addition for emoji script after that for various graphic-like
characters, since they overlap, and we want the emoji setting to win.
* lisp/term.el (term-emulate-terminal): Don't record the selection
of the window here, because we're not doing a user-level window
selection, but just selecting the window for internal purposes
(bug#41984).
* doc/emacs/programs.texi (Imenu): Document it.
* lisp/imenu.el (imenu-max-index-time): New user option.
(imenu-default-create-index-function, imenu--generic-function):
Use it (bug#18696).
* lisp/mh-e/mh-e.el (mh-variant-gnu-mh-info, mh-variant-nmh-info):
Run install-mh, not mhparam, to check whether an MH variant is
installed on the system. mhparam fails if no user profile is found,
so it is not a reliable check of the state of the system as a whole.
Tested with:
nmh 1.4, nmh 1.7.1, GNU Mailutils 2.2, GNU Mailutils 3.7, GNU Mailutils 3.13
* src/xterm.c (x_draw_stretch_glyph_string):
* src/w32term.c (w32_draw_stretch_glyph_string): Fix drawing
stretch glyphs when the window is hscrolled. (The original
pre-Jan-2021 code was almost correct, except that it used
'window_box_left_offset' instead of 'window_box_left', and didn't
restrict the background_width fixup to text-area.) (Bug#50564)
* admin/notes/unicode: Describe how to update emoji for new Unicode release.
* admin/unidata/Makefile.in: Pass emoji-data.txt to
blocks.awk script.
* admin/unidata/README: Add pointer to emoji-data.txt file.
* admin/unidata/blocks.awk: Parse emoji-data.txt, add emoji codepoints
to the 'emoji' script (except for the ASCII ones).
* admin/unidata/emoji-data.txt: New file.
* etc/NEWS: Describe new 'emoji' script.
* etc/TODO: Update item about 'emoji' script.
* lisp/international/fontset.el (script-representative-chars): Add
'emoji' script.
(setup-default-fontset): Add 'emoji' script. Use "Noto Color Emoji"
as default font for it.
For better compatibility with different systems.
Performance is unaffected, except in very pathological cases
(~100000 matches), and even then the overhead of 'sort' is comparable.
* lisp/progmodes/xref.el (xref-search-program-alist):
Drop the piping through 'sort'.
(xref-matches-in-files): Sort here instead.
Do that to both searchers' output as well now.
