* lisp/whitespace.el (whitespace-style):
(whitespace-style-value-list):
(whitespace-toggle-option-alist):
(global-whitespace-toggle-options):
(whitespace-help-text):
(whitespace-interactive-char):
(whitespace-style-face-p):
(whitespace-color-on):
(whitespace-lines-regexp): New whitespace style `lines-char', which
highlights only the first character over the whitespace-line-column
limit (bug#55980).
* lisp/x-dnd.el (x-dnd-types-alist, x-dnd-known-types): Add
DndTypeFile and DndTypeText.
(x-dnd-init-frame): Add _DND_PROTOCOL.
(x-dnd-handle-drag-n-drop-event): Handle _DND_PROTOCOL events.
(x-dnd-handle-old-kde): Drop event if proto is too new.
(x-dnd-offix-id-to-name): New list.
(x-dnd-handle-offix-file, x-dnd-handle-offix): New functions.
* src/xterm.c (x_atom_refs): Add DndProtocol and _DND_PROTOCOL.
(x_coords_from_dnd_message): Handle the old KDE protocol.
* src/xterm.h (struct x_display_info): New atoms.
* src/xterm.c (struct xm_drag_motion_reply): New struct.
(xm_read_drag_motion_reply): New function.
(x_coords_from_dnd_message): Handle those messages as well.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker)
(byte-optimize-let-form, byte-optimize-letX):
* lisp/emacs-lisp/bytecomp.el (byte-compile-unwind-protect):
Simplify source optimisation and codegen code that can now rely on
normalised let/let* and unwind-protect forms.
Make cconv work for dynamically bound code and always run it.
This allows later stages to benefit from transformations and
normalisations in cconv.
* lisp/emacs-lisp/bytecomp.el (byte-compile-preprocess): Always run
cconv.
* lisp/emacs-lisp/cconv.el (cconv--analyze-function)
(cconv-analyze-form): In dynbound code, treat all variable bindings
as dynamic (lambda, let, let* and condition-case).
Early normalisation of setq during macroexpand-all allows later
stages, cconv, byte-opt and codegen, to be simplified and duplicated
checks to be eliminated.
* lisp/emacs-lisp/macroexp.el (macroexp--expand-all):
Normalise all setq forms to a sequence of (setq VAR EXPR).
Emit warnings if necessary.
* lisp/emacs-lisp/cconv.el (cconv-convert, cconv-analyze-form):
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker):
* lisp/emacs-lisp/bytecomp.el (byte-compile-setq):
Simplify.
* test/lisp/emacs-lisp/bytecomp-tests.el: Adapt and add tests.
* test/lisp/emacs-lisp/bytecomp-resources/warn-variable-setq-nonvariable.el;
* test/lisp/emacs-lisp/bytecomp-resources/warn-variable-setq-odd.el:
New files.
* lisp/international/iso-transl.el (iso-transl-char-map): Add
sequences for {AE,ae,G,g} with macron.
* lisp/leim/quail/latin-post.el ("latin-postfix"): Add missing entries
for {AE,ae,G,g} with macron.
* lisp/leim/quail/latin-pre.el ("latin-prefix"): Add entries for
'letter with macron' for {A,a,E,e,AE,ae,I,I,O,o,U,u,Y,y} with macron.
(Bug#55668)
* lisp/files.el (dir-locals-read-from-dir): We want the time stamp
of the actual file, not the time stamp of the symlink (if
.dir-locals.el is a symlink) (bug#46122).
* lisp/term/ns-win.el (global-map): set-frame-font asks for a font
using the minibuffer, but the former ns-popup-font-panel always showed
the graphical font panel on macOS. To preserve the same behavior,
bind it to menu-set-font, which is also called by Options, Set Default
Font (bug#55967).
* lisp/net/tramp.el (tramp-run-real-handler):
Handle also functions which use a `tramp-file-name' for the file
name handler. (Bug#55832)
(tramp-get-home-directory, tramp-get-remote-uid)
(tramp-get-remote-gid): VEC can also be nil.
* src/xterm.c (xm_read_drop_start_message): New function.
(xm_read_drag_motion_message): Check that the originator is
correct.
(x_coords_from_dnd_message): Read drop start messages as well.
This avoids an extra sync, which matters when dropping onto
Emacs running over a slow connection.
* src/xselect.c (x_handle_dnd_message): New args
`root_window_coords', `root_x' and `root_y'.
* src/xterm.c (x_coords_from_dnd_message): New function.
(handle_one_xevent): Pass root window coordinates to
x_handle_dnd_message.
* src/xterm.h: Update prototypes.
* src/xfont.c (xfont_list_pattern): Initialize a local.
Although I’m not sure this is needed, it doesn’t change
behavior (except possibly to make undefined behavior defined).
* lisp/textmodes/dns-mode.el (dns-mode-font-lock-keywords): Match
complete words like SOA and not all words that contain the string
SOA (bug#55944).
Copyright-paperwork-exempt: yes
* doc/emacs/search.texi (Query Replace): Document it.
* lisp/replace.el (query-replace-help): Amend help text.
(query-replace-map): Bind `E' to the exact case replacement.
(perform-replace): Allow editing a replacement with exact case
(bug#8504).
* lisp/language/indian.el ("Meetei Mayek"): New language environment.
Add composition rules for Meetei Mayek. Add sample text and input method.
* lisp/international/fontset.el (script-representative-chars)
(setup-default-fontset): Support Meetei Mayek.
* lisp/leim/quail/indian.el ("meetei-mayek"): New input method.
* etc/HELLO: Add a Meetei Mayek greeting.
* etc/NEWS: Announce the new language environment.
