* src/xterm.c (handle_one_xevent): Don't abort on DeviceChanged
if the device couldn't be found, instead regenerating the device
hierarchy to see if it was enabled.
* lisp/gnus/gnus-search.el (*-remove-prefix): For all engine defaults,
remove incorrect docs stating this is a regexp (it's a string). Also,
use `expand-file-name' to get the correct default value, not `concat'
and (getenv "HOME").
* doc/misc/gnus.texi: The options `gnus-use-toolbar',
`gnus-toolbar-thickness', and `gnus-summary-mail-toolbar' no longer
exist. Other options in this section have been renamed from "toolbar"
to "tool-bar".

faces more complete.
(Face Remapping): Improve wording of a recent addition; add
cross-reference to "Basic Faces".
* lisp/abbrev.el (abbrev-table-p): Ignore the error.

`error' if it turns out that we're not really in an obarray (bug#53988).

Haiku as well.
* lisp/term/haiku-win.el (haiku--selection-type-to-mime): Update

handled by the regular selection machinery.

* doc/lispref/commands.texi (Disabling Commands): Document the
low-level stuff.
* lisp/simple.el (command-execute): Respect the `(query ...)'
value for `disabled'.
(command-execute--query): New function.
(command-query): New function.
Xwidgets have worked on NS for a long time, "smooth scrolling"
is now available as `pixel-scroll-precision-mode' for all GUI
platforms, and some mouse gestures have been implemented on NS
and X.
* src/xterm.c (xi_reset_scroll_valuators_for_device_id): New
argument `pending_only'.
(handle_one_xevent): Reset pending scroll valuators on XI_Enter
and mark valuators updated via DeviceChanged events as pending.
* src/xterm.h (struct xi_scroll_valuator_t): New field
`pending_enter_reset'.
* src/xterm.c (x_init_master_valuators): Generate valuators for
both master and slave devices.
(handle_one_xevent): Find current valuator info and use that to
populate scroll valuators after a device changed.
* src/xterm.c (handle_one_xevent): Just update the device that
was changed on DeviceChanged and only do hierarchy recalculation
upon HierarchyChanged events.

use ImportBits.
(BBitmap_import_fringe_bitmap): New function.
* src/haiku_support.h: Update prototypes.

short array to BBitmap_import_fringe_bitmap instead.

don't message, but return the string.
* lisp/mail/ietf-drums.el:
+ (ietf-drums-skip-comment): New helper function.
+ (ietf-drums-remove-comments): Use ietf-drums-skip-comment.
+ (ietf-drums-remove-whitespace): Handle unterminated quotes and
comments, as ietf-drums-remove-comments already does.
* test/lisp/mail/ietf-drums-tests.el:
+ Test unterminated quote and comment for
ietf-drums-remove-whitespace and ietf-drums-remove-comments (bug#53965).
* src/xwidget.c (dummy_tooltip_string): New variable.
(xw_maybe_synthesize_crossing): Call `xg_prepare_tooltip' to
disable tooltips on WebKitGTK 2.34 or later.

`xinerama_supported_p'.

non-NULL.
(handle_one_xevent): If f is NULL and the configure event is for
any's edit widget, use that instead.
Make the context switch code handle buffer-local variables more
correctly by reusing the code originally written for `backtrace-eval`.
This has the side benefit of making the `saved_value` field unused.
* src/lisp.h (enum specbind_tag): Remove `saved_value` field.
(rebind_for_thread_switch, unbind_for_thread_switch): Delete decls.

common code between the different branches.
(rebind_for_thread_switch, -unbind_for_thread_switch): Move to `thread.c`.
(specpdl_unrewind): New function, extracted from `backtrace_eval_unrewind`.
Use `SET_INTERNAL_THREAD_SWITCH`. Skip the buffer & excursion unwinds
depending on new arg `vars_only`.
(backtrace_eval_unrewind): Use it.
(mark_specpdl): Don't mark `saved_value`.
* src/thread.c (rebind_for_thread_switch, unbind_for_thread_switch):
Move from `eval.c` and rewrite using `specpdl_unrewind`.
* test/src/thread-tests.el (threads-test-bug48990): New test.

"warning: jobserver unavailable: using -j1. Add '+' to parent make rule".
This changeset is based on code originally posted by
Kenichi Handa <handa@gnu.org> as part of discussing bug#20140,
with a few adjustments and changes, mainly to support R2L
text and provide a user option to control the feature.
* src/xdisp.c (compute_stop_pos, next_element_from_buffer)
(composition_reseat_it): Don't allow auto-composing characters
past point when 'composition-break-at-point' is non-nil.

(redisplay_internal, redisplay_window): Disable "just move the
cursor" optimizations when 'composition-break-at-point' is non-nil.
* src/keyboard.c (command_loop_1): Force redisplay when
'composition-break-at-point' is non-nil.
* lisp/cus-start.el (standard): Provide customization form for
'composition-break-at-point'.
* etc/NEWS: Announce the new feature.
SPECPDL_INDEX becomes much faster because the pointer subtraction,
expensive because of the inconveniently sized specpdl records, is now
gone. This translates to a useful speedup on a wide variety of code.
* src/lisp.h (specpdl_ref, wrap_specpdl_ref, unwrap_specpdl_ref):
Rename member.
(specpdl_count_to_ref, specpdl_ref_to_count)
(specpdl_ref_add, specpdl_ref_to_ptr, SPECPDL_INDEX):
Count offset in bytes rather than in records.
