* src/dispextern.h (struct it): New 'narrowed_zv' field.
* src/xdisp.c (init_iterator): Set the field.
(get_narrowed_zv): New function to set the field.
(handle_fontified_prop): Use the field, together with 'narrowed_begv',
to narrow the portion of the buffer that 'Vfontification_functions'
will see. Also bind 'inhibit-widen'.
(get_narrowed_len): New function, factored out of 'get_narrowed_begv'.
(unwind_narrowed_zv): New function.
* src/editfns.c (syms_of_editfns): New variable and symbol 'inhibit-widen'.
(Fwiden): Do nothing when 'inhibit-widen' is non-nil.
* src/xdisp.c (redisplay_window): Increase the threshold above which
long lines detection is performed in the buffer. This should avoid
triggering that detection for most simple editing operations.
* src/lisp.h (modiff_incr): Explain why the counter is incremented
logarithmically.
* src/buffer.h (struct buffer_text): Adapt the comment about the
'modiff' field accordingly.
* src/buffer.c (modify_overlay): Increase the counter by 1 instead of
the size of the buffer section on which the overlay is placed.
* etc/NEWS: Small improvement.
* lisp/subr.el (lsh): Note the general preference for `ash`.
* lisp/emacs-lisp/shortdoc.el (number): Remove entry for `lsh`.
It was identical to that for `ash` which is misleading.
Shortdoc is very helpful for finding the right function to use,
and `lsh` is just for compatibility at this point.
* lwlib/xlwmenu.c (xlwMenuResources, display_menu_item)
(make_drawing_gcs, make_shadow_gcs, openXftFont, XlwMenuRealize)
(XlwMenuSetValues): Use -1 as the default for
highlight_foreground. Replace that with the normal foreground
when creating GCs. Reported by Colin Baxter
<m43cap@yandex.com>.
* lisp/term/haiku-win.el (haiku-dnd-wheel-count): New defvar.
(haiku-note-wheel-click, haiku-handle-drag-wheel): New
functions.
* src/haiku_support.cc (EmacsWindow): Get rid of window ID
logic.
(MessageReceived, MouseMoved, be_drag_message): Use thread ID to
identify windows instead of window ID.
* src/haikuselect.c (Fhaiku_drag_message): Record whether or not
the DND frame is a valid drop target.
(haiku_note_drag_wheel): New function.
(syms_of_haikuselect): New defvar.
* src/haikuterm.c (haiku_read_socket): Call
`haiku_note_drag_wheel' when appropriate.
* src/haikuterm.h: Update prototypes.
Previously, it considered only windows on 'visible' frames (according
to get-buffer-window). This seemed correct at first, but it's not
much use for multiple TTY frames and not particularly reliable on GUI
frames either. There's no reliable way to tell what is actually
visible, so it's best to assume that users setup frames that are
indeed visible when using this parameter.
* lisp/emacs-lisp/eldoc.el (eldoc--echo-area-prefer-doc-buffer-p):
Consider all frames.
* src/lisp.h (modiff_incr): Add a parameter to 'modiff_incr' to record
the extent of the modification.
* src/insdel.c (insert_1_both, insert_from_string_1, insert_from_gap,
insert_from_buffer_1, adjust_after_replace, replace_range,
replace_range_2, del_range_2, modify_text): Add an argument to each
call to 'modiff_incr'.
* src/textprop.c (modify_text_properties): Add an argument to the call
to 'modiff_incr'.
* src/buffer.c (Frestore_buffer_modified_p, Fbuffer_swap_text,
modify_overlay): Add an argument to each call to 'modiff_incr'.
* src/xdisp.c (redisplay_window): Use the improved version of 'MODIFF'
for the heuristic.
We used to use a very "optimistic" regexp which worked well for
longish symbol names but suffered from too many false positives on
short names. Use a more restrictive regexp, which should make the
recent "weed out" change unnecessary.
This in turn requires the use of '...' more consistently in etc/NEWS* files.
* lisp/help-fns.el (help-fns--first-release-regexp): New function.
(help-fns--first-release): Use it. Fix minor issue with the Emacs
version regexp.
(help-fns--mention-first-release): Undo last change.
* etc/NEWS*: Replace `...' with '...'. Indent code examples by at
least 2 spaces. Add previously missing '...' quotes around many of
the variables and functions described.
