* lisp/subr.el (replace-string-in-region, replace-regexp-in-region):
Narrow to region before iterating over matches, instead of giving a
bound to the search functions.
* test/lisp/subr-tests.el (test-replace-string-in-region): Add
regression tests (bug#57733).
* lisp/whitespace.el (whitespace--empty-at-bob-matcher,
whitespace--empty-at-eob-matcher, whitespace--update-bob-eob,
whitespace-color-off, whitespace-color-on,
whitespace-empty-at-bob-regexp, whitespace-empty-at-eob-regexp,
whitespace-looking-back, whitespace-post-command-hook): Redo the
`empty' line highlighting logic to ensure that a buffer change causes
all affected `empty' lines to become (un)highlighted (bug#37467).
Also, for improved UX, don't highlight BoB empty lines at or below
point (not just when point is at 1), or EoB empty lines at or above
point (not just when point is `eobp').
(whitespace-bob-marker, whitespace-eob-marker): Clarify documentation.
* test/lisp/whitespace-tests.el (whitespace--with-test-buffer,
whitespace--fu, whitespace-tests--empty-bob,
whitespace-tests--empty-eob): Add tests.
* lisp/whitespace.el (whitespace-empty-at-bob-regexp): Include any
last line trailing whitespace in the BoB empty line match to ensure
that those characters get highlighted.
* lisp/emacs-lisp/ert-x.el (ert-with-test-buffer-selected): New
convenience macro that extends `ert-with-test-buffer' by displaying
the test buffer in a temporary selected window. This makes it easier
to simulate user input in the body via `execute-kbd-macro'.
* test/lisp/emacs-lisp/ert-x-tests.el
(ert-test-test-buffer-selected/*): Add tests.
* src/xterm.c (xm_get_drag_window_1): Add comment explaining
side effect of x_special_window_exists_p.
(handle_one_xevent): Clear Motif drag window upon DestroyNotify.
In addition to debugging, it also reduces syncs necessary to
communicate via the Motif protocol after a defective/old client
sets the drag window without setting the disconnect mode.
* src/xterm.c (x_dnd_send_enter, x_dnd_send_position)
(x_dnd_send_leave, x_dnd_send_drop, x_dnd_do_drop): New
parameter `toplevel'. Use it as the window in sent client
messages.
(x_dnd_cancel_dnd_early, x_dnd_cleanup_drag_and_drop)
(x_dnd_process_quit, x_dnd_update_state, handle_one_xevent)
(x_connection_closed): Give the right toplevel to the client
message sending functions.
* doc/lispref/minibuf.texi (Text from Minibuffer): Mention it.
* lisp/minibuffer.el (format-prompt): Run through
`substitute-command-keys' (bug#51040).
* doc/lispref/help.texi (Keys in Documentation): Remove duplicate
entry for 'text-quoting-style'. Document the function with the same
name instead.
* src/doc.c (Ftext_quoting_style): Doc fix: clarify the return values.
(syms_of_doc) <Vtext_quoting_style>: Doc fix: clarify that you should
not read the value of this variable directly; use Ftext_quoting_style
instead (bug#51040).
* lib-src/emacsclient.c (main): Use right length modifier when
printing uintmax_t.
* src/alloc.c (check_pure_size): Use right length modifier when
printing ptrdiff_t.
* lisp/vc/vc-git.el
(vc-git-annotate-switches-safe-p): New predicate function.
(vc-git-annotate-switches): Use above new predicate function to
check if it's :safe.
This code fix is by Stefan Monnier (Bug#57699).
* src/process.c (init_process_emacs) [HAVE_GLIB && !WINDOWSNT]:
Adjust to Glib 2.73.2 behavior change on Linux kernel 5.3+.
* lisp/comint.el
(comint-indent-input-line):
(comint-indent-input-line-default):
(comint-indent-input-region):
(comint-indent-input-region-default): New functions that implement a
general mechanism for input indentation through an indirect buffer in
comint derived major modes.
* lisp/shell.el (shell-mode): Set up input indentation according to
sh-mode (bug#51940).
* lisp/shell.el (shell-mode): Enable highlighting of non-existent
commands if requested.
(shell-highlight-undef-aliases):
(shell-highlight-undef-remote-file-name-inhibit-cache): New user
options.
(shell-highlight-undef-mode): New minor mode.
(shell-highlight-undef-defined-face):
(shell-highlight-undef-undefined-face):
(shell-highlight-undef-alias-face): New faces.
(shell-highlight-undef--exec-cache):
(shell-highlight-undef--face):
(shell-highlight-undef-keywords):
(shell-highlight-undef-regexp):
(shell-highlight-undef--executable-find):
(shell-highlight-undef-matcher):
(shell-highlight-undef--indirect):
(shell-highlight--setup):
(shell-highlight-undef-reset-mode): New functions and buffer local
variables (bug#51940).
* lisp/ielm.el (ielm-comint-fl-enable): New user option to control
input fontification.
(ielm-indirect-setup-hook): New hook.
(inferior-emacs-lisp-mode): Set up and enable input fontification.
* lisp/comint.el
(comint-indent-input-line):
(comint-indent-input-line-default):
(comint-indent-input-region):
(comint-indent-input-region-default): New functions that implement a
general mechanism for input indentation through an indirect buffer in
comint derived major modes.
* lisp/shell.el (shell-mode): Set up input indentation according to
sh-mode (bug#51940).
* lisp/comint.el
(comint-indent-input-line):
(comint-indent-input-line-default):
(comint-indent-input-region):
(comint-indent-input-region-default): New functions that implement a
general mechanism for input indentation through an indirect buffer in
comint derived major modes.
* lisp/shell.el (shell-mode): Set up input indentation according to
sh-mode (bug#51940).
* lisp/comint.el
(comint-indent-input-line):
(comint-indent-input-line-default):
(comint-indent-input-region):
(comint-indent-input-region-default): New functions that implement a
general mechanism for input indentation through an indirect buffer in
comint derived major modes.
* lisp/shell.el (shell-mode): Set up input indentation according to
sh-mode (bug#51940).
* lisp/emacs-lisp/backtrace.el (backtrace-mode-map): Don't bind
the "s" command, because it's meaningless outside modes that have
set the backtrace-goto-source-functions variable (and only edebug
does that) (bug#57674).
* lisp/emacs-lisp/edebug.el (edebug-pop-to-backtrace): Use it.
(edebug-backtrace-mode-map, edebug-backtrace-mode): New mode.
