* doc/emacs/fixit.texi (Spelling): Replace mentions of
flyspell-use-mouse-3-for-menu with context-menu-mode.
* lisp/mouse.el (context-menu-map): Use the function from the
text property context-menu-function at mouse click event.
* lisp/textmodes/flyspell.el (flyspell--set-use-mouse-3-for-menu):
Remove function.
(flyspell-use-mouse-3-for-menu): Remove defcustom added recently in 28.1.
(flyspell-context-menu): New function.
(flyspell-mode): Don't call flyspell--set-use-mouse-3-for-menu.
(flyspell-mode-on): Replace flyspell-use-mouse-3-for-menu
with context-menu-mode.
(make-flyspell-overlay): When context-menu-mode is non-nil,
put overlay context-menu-function with flyspell-context-menu
instead of using keymap flyspell-mouse-map.
* lisp/userlock.el (userlock--check-content-unchanged): Make the
assertion more robust -- we may be called here from a different
contexts if `query-about-changed-file' is nil.
* lisp/calendar/timeclock.el (timeclock--previous-workday): New
variable.
(timeclock-find-discrep): Use it to flush values when
timeclock-workday changes (bug#50216).
(timeclock-mode-line-display): Mention `timeclock-workday' setting
in doc string.
* lisp/progmodes/compile.el (compilation-find-file): Avoid
`expand-file-name' when computing the file names, because that will
reliably give the wrong result when there's symlinks and ".."
involved (bug#8035).
* lisp/dired.el (dired-chmod-program): Make into a defvar and make
obsolete (bug#50190).
* lisp/net/ange-ftp.el (ange-ftp-process-file): Remove usage of
dired-chmod-program.
* doc/misc/message.texi (Message Headers): Clarify that it comes from
the Latin "res" meaning "in the matter of" rather than "in response
to" as claimed previously (see RFC-2822).
* lisp/finder.el (finder-compile-keywords): Now that 'version' is
set for more files, it is no longer necessary to check that we have
a version when picking the file from which to take the description.
Doing so caused built-in packages (where the version is known) to have
their package description taken from the last .el file that matched the
file name pattern, usually the last source file in the sub-directory.
This bug was introduced in July 2019 and first released in Emacs 27.1.
Thanks to Michael Albinus for reviewing this patch.
* lisp/emacs-lisp/tabulated-list.el (tabulated-list-print): Ensure
that we delete remaining lines if the list has gotten shorter
(bug#50194).
Copyright-paperwork-exempt: yes
* doc/emacs/misc.texi (Shell Mode): Document it.
* lisp/comint.el (comint-osc-handlers, comint-osc--marker): New
variables.
(comint-osc-process-output): New function.
(comint-osc-hyperlink-map): New map.
(comint-osc-hyperlink-handler): New function.
* lisp/textmodes/conf-mode.el (conf-mode):
* lisp/textmodes/tex-mode.el (tex--redirect-to-submode): The
previous hack to these redirections would disable all local
variables. Try to work around this a bit more.
* doc/lispref/modes.texi (Other Font Lock Variables):
* lisp/jit-lock.el (jit-lock-functions, jit-lock-register):
Document the return value of the fontification functions.
* doc/lispref/searching.texi (Extending Rx): Add example illustrating
how to define a user-defined Rx form that performs computation,
from a discussion with Michael Herdeegen (bug#50136).
* lisp/emacs-lisp/rx.el (rx): Clarify evaluation time for `eval`.
* doc/emacs/frames.texi (Menu Mouse Clicks): Mention S-F10
to pop up the context menu.
* src/callint.c (Fcall_interactively):
Use inhibit_mouse_event_check for the case 'e'.
(inhibit-mouse-event-check): New variable.
https://lists.gnu.org/archive/html/emacs-devel/2021-08/msg00733.html
* lisp/progmodes/cperl-mode.el (cperl-mode): Use
`cperl-font-lock-syntactic-face-function'.
(cperl-commentify): Add a docstring, eliminate unused formal
parameter `noface'.
(cperl-is-here-doc-p): New function to detect whether "<<" starts
a here-document, factored out from `cperl-find-pods-heres'.
(cperl-here-doc-functions): New variable: List of functions which
allow here-documents as parameters, for use in
`cperl-is-here-doc-p'.
(cperl-process-here-doc): New function, factored out from
`cperl-find-pods-heres'. Fixed to keep correct fontification
after non-interactive (elisp) changes (Bug#14343, Bug#28962).
(cperl-find-pods-heres): Extend the doc-string to describe all
parameters. Don't remove text properties in recursive calls on
the same line. Call `cperl-process-here-doc' when appropriate.
(cperl-font-lock-syntactic-face-function): New function to
highlight c-style comments as here-documents (adapted from
perl-mode.el).
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-test-identify-heredoc): New test for the new function
`cperl-is-here-doc-p'.
(cperl-test-identify-no-heredoc): New test for the new function
`cperl-is-here-doc-p', testing constructs which start with "<<"
but are no here-documents.
(cperl-test-here-doc-missing-end): New test to verify correct
detection of a missing here-document delimiter.
(cperl-test-bug-14343): New test to verify that inserting text
into a here-document with elisp does not break fontification.
