If automatic character composition triggers GC, and
'garbage-collection-messages' are turned on, we could have the
bidi cache reset while processing RTL text, which would then
consistently crash.
* src/xdisp.c (display_echo_area_1): Protect the bidi cache
against changes inside 'try_window'.
* lisp/tab-bar.el (switch-to-buffer-other-tab): Use
'window-normalize-buffer-to-switch-to' on 'buffer-or-name',
like does 'pop-to-buffer' used by 'switch-to-buffer-other-frame',
instead of raising the error "Invalid buffer" on a non-existent buffer name.
* lisp/simple.el (next-error-no-navigation-try-current):
Extract from the case #2 in next-error-find-buffer (bug#40919).
(next-error-find-buffer-function): Use it as the default.
* src/xdisp.c (get_visually_first_element)
(Fbidi_find_overridden_directionality):
* src/cmds.c (Fend_of_line): Use FETCH_BYTE instead of FETCH_CHAR,
and byte position instead of character position, to access
individual bytes of buffer text. This avoids producing invalid
characters and accessing wrong buffer positions. (Bug#41520)
* doc/lispref/text.texi (Interpolated Strings): Fix typos. Don't
document modifier for default space padding as it's redundant and
inconsistent with the docstring and implementation of format-spec.
* lib-src/etags.c (pfnote): Instead of raising an assertion when
we get an empty tag name, return immediately. (Bug#41465)
* test/manual/etags/ETAGS.good_1:
* test/manual/etags/ETAGS.good_2:
* test/manual/etags/ETAGS.good_3:
* test/manual/etags/ETAGS.good_4:
* test/manual/etags/ETAGS.good_5:
* test/manual/etags/ETAGS.good_6: Adapt to latest changes in
etags.
* doc/lispref/display.texi (Fontsets): Improve the accuracy of a
cross-reference to "Character Properties".
* doc/emacs/mule.texi (Fontsets, Modifying Fontsets): Improve the
documentation of fontsets and how to modify them.
* lisp/version.el: Don’t put an RCS Id style string into the
executable via purecopy, as this does not work with the pdumper.
* src/emacs.c (RCS_Id): New constant, for 'ident'.
(cherry picked from commit 3d1bcfba5e)
* doc/lispref/control.texi (Processing of Errors): Improve indexing by
adding the word form "handle" in addition to "handling". With thanks
to Eli Zaretskii.
Inspired by patch proposed by Dmitry Gutov (Bug#40671#393)
and by further comments by him and by Michael Heerdegen
in the same bug report.
* doc/lispintro/emacs-lisp-intro.texi (setcar):
Don’t push mutability here.
* doc/lispref/eval.texi (Self-Evaluating Forms, Quoting)
(Backquote):
* doc/lispref/lists.texi (Modifying Lists):
* doc/lispref/objects.texi (Lisp Data Types, Mutability):
* doc/lispref/sequences.texi (Array Functions, Vectors):
* doc/lispref/strings.texi (String Basics, Modifying Strings):
Don’t use the word “constant” to describe all values that
a program should not change.
* doc/lispref/objects.texi (Mutability):
Rename from “Constants and Mutability”. All uses changed.
In a footnote, contrast the Emacs behavior with that of Common
Lisp, Python, etc. for clarity, and say the goal is to be nicer.
* doc/emacs/building.texi (Lisp Libraries): Describe how to
manually load packages in the init file. Mention the 'site-lisp'
subdirectory of the default 'load-path'.
* doc/emacs/package.texi (Packages): Describe manual installation
of ELisp packages. Suggested by Jean-Christophe Helary
<jean.christophe.helary@traduction-libre.org>.
Some themes (like dracula) make the region face inherit from some
other face. If the background color of the region was inherited,
`indicate-copied-region' did the switch-point-and-mark-twice dance
which is not visible in case the region is highlighted. It just
looked like Emacs would hang for a second after M-w.
* lisp/simple.el (indicate-copied-region): Consider face inheritance
when checking region face background.
While there, add a unit test to verify the behavior.
* doc/lispref/os.texi (Command-Line Arguments): Fix documentation: the
option string in 'command-switch-alist' does include leading hyphens.
Also mention that 'command-switch-alist' parsing ignores equals signs
in options.
* test/lisp/startup-tests.el
(startup-tests/command-switch-alist): New unit test.
* doc/emacs/calendar.texi (Holidays): Revert previous change, as
bahai.org spells it “Bahá’í” (with U+2019 RIGHT SINGLE QUOTATION
MARK) and that’s good enough for us.
* src/xdisp.c (syms_of_xdisp): Add reference to manual in
documentation strings for variables related to fill column indicators.
* lisp/display-fill-column-indicator.el (display-fill-column-indicator)
(display-fill-column-indicator-mode): Add reference to manual.
* lisp/menu-bar.el (menu-bar-showhide-tool-bar-menu): Fix typo
that makes the radio buttons pretend that the tool bar is always
shown on the left side of the frame.
* lisp/emacs-lisp/byte-run.el (with-suppressed-warnings): Refer to
'byte-compile-warnings' instead of 'byte-compile-warning-types', as
only the former variable documents the available warning types.
* lisp/hi-lock.el (hi-lock-mode, hi-lock-face-buffer)
(hi-lock-face-phrase-buffer, hi-lock-face-symbol-at-point):
Clarify when 'hi-lock-mode' will use Font Lock and when it will
use overlays. (Bug#41124)
