* 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/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.
* doc/lispref/frames.texi (Finding All Frames): Clarify what it
means to "consider".
* src/frame.c (Fnext_frame): Rewrite doc string to say what the
parameters actually mean (bug#13339).
* doc/emacs/files.texi (Auto Save Files): Document it.
* lisp/cus-start.el (standard): Add customize form.
* lisp/files.el (delete-auto-save-files): Move definition to C
(since it's used in the C layer).
* src/buffer.c (Fkill_buffer): Use the new variable (and remove
the old code that apparently didn't trigger for
kill-buffer/delete-auto-save-files.
(syms_of_buffer): Add new variable
kill-buffer-delete-auto-save-files and move definition of
delete-auto-save-files here (bug#21612).
* lisp/net/tramp-sh.el (tramp-sh-handle-copy-directory): Fix the case
NEWNAME is a directory name with a trailing slash.
* lisp/net/tramp-smb.el (tramp-smb-handle-copy-directory):
Implement `copy-directory-create-symlink'. (Bug#10897)
* test/lisp/net/tramp-tests.el
(tramp--test-ignore-make-symbolic-link-error): Move up.
(tramp-test15-copy-directory): Extend test.
