The existing XIC implementation doesn't work when using Gtk IM Context.
Instead, `gtk_im_context_set_cursor_location` should be used
to update the cursor information for the input method.
* src/pgtkim.c (pgtk_im_set_cursor_location): New function to tell gtk
cursor location.
* src/pgtkterm.c (pgtk_draw_window_cursor): Remove invalid code and
add new code to call the function.
* src/pgtkterm.h: Add the function declaration.
* lisp/mail/rmail.el (rmail-show-message-set-modified): New
option.
(rmail-show-message-1): If 'rmail-show-message-set-modified' is
non-nil, don't reset the buffer's modified state. (Bug#45941)
* etc/NEWS: Announce the new option.
* lisp/dired.el (dired-clean-up-after-deletion): Kill the buffers
if you have `dired-clean-up-buffers-too' set and
`dired-clean-confirm-killing-deleted-buffers' nil (bug#38037).
Copyright-paperwork-exempt: yes
* lisp/vc/vc-dir.el (vc-dir-mode-map):
Remove the mouse-2 binding (bug#13692).
(vc-dir-mode): Update the docstring accordingly.
(vc-dir-status-mouse-map): New variable.
(vc-default-dir-printer): Use it on the state buttons.
* lisp/vc/vc-git.el (vc-git-dir-printer): Same.
* lisp/play/handwrite.el: Use lexical-binding. Remove redundant
:group args. Minor cleanups.
(handwrite): Minor cleanups.
(handwrite-set-pagenumber-off, handwrite-set-pagenumber-on): Make
comments into docstrings.
* src/w32fns.c (w32_version_string) [WINDOWSNT]: New function.
* src/w32common.h (w32_version_string) [WINDOWSNT]: Add prototype.
* src/editfns.c (init_editfns) [WINDOWSNT]: Produce a non-nil
string with the OS version.
* simple.el (shell-command, shell-command-on-region): Set
revert-buffer-function buffer-locally, not globally. Also, avoid an
unnecessary call to (current-buffer) by taking advantage of the
closure (bug#46151).
* lisp/generic-x.el (generic-mode-ini-file-find-file-hook): Fix my
previous commit; for some reason 'function' produces a warning here
while 'quote' does not.
* lisp/emacs-lisp/bindat.el: Use lexical-binding.
(bindat--unpack-group, bindat--length-group, bindat--pack-group):
Declare `last` and `tag` as dyn-scoped.
(bindat-unpack, bindat-pack): Bind `bindat-raw` and `bindat-idx` via
`let` rather than via the formal arglist.
* lisp/emacs-lisp/package-x.el:
* lisp/emacs-lisp/generic.el:
* lisp/emacs-lisp/eieio-opt.el:
* lisp/emacs-lisp/derived.el:
* lisp/emacs-lisp/crm.el: Use lexical-binding.
* lisp/emacs-lisp/helper.el: Use lexical-binding.
(Helper-help-map): Move initialization into declaration.
* lisp/emacs-lisp/regi.el: Use lexical-binding.
(regi-interpret): Remove unused var `tstart`.
Declare `curframe`, `curentry` and `curline` as dyn-scoped.
* lisp/emacs-lisp/shadow.el: Use lexical-binding.
(load-path-shadows-find): Remove unused var `file`.
Tighten a regexp, use `push`.
* lisp/emacs-lisp/tcover-ses.el: Use lexical-binding. Require `ses`.
Remove correspondingly redundant declarations.
(ses--curcell-overlay): Declare.
(ses-exercise): Use `dlet` and use a properly-prefixed var name.
Fix name of `curcell-overlay` variable.
* lisp/emacs-lisp/unsafep.el: Use lexical-binding.
(unsafep): Bind `unsafep-vars` via `let` rather than via the formal arglist.
