* lisp/x-dnd.el (x-dnd-hscroll-flags): Delete function.
(x-dnd-get-modifiers, x-dnd-wheel-modifier-type): New functions.
(x-dnd-mwheel-scroll): Use that to determine hscroll instead.
* src/window.c (set_window_hscroll): Mark window as needing
redisplay if the hscroll really changed.
* src/xterm.c (x_get_last_toolkit_time): New function.
(x_scroll_bar_to_input_event)
(x_horizontal_scroll_bar_to_input_event): Use it to retrieve
toolkit time.
(xg_scroll_callback, xg_end_scroll_callback): Set last user time
if possible.
* lisp/progmodes/compile.el (compilation-parse-errors-function): Remove.
(compilation--parse-region): Simplify accordingly.
(compilation--compat-parse-errors): Remove function, not used any more.
(compilation-error-list, compilation-parsing-end)
(compilation-old-error-list): Remove vars, not used any more.
(compilation-last-buffer): Mark as obsolete (sadly, forgot to do that
back in Emacs-22).
* lisp/textmodes/tex-mode.el: Remove old code that was needed for
Emacs<24.
* lisp/progmodes/prolog.el (prolog-consult-compile): Remove long-dead code.
(compilation-parse-errors-function): Remove declaration, not used any more.
(prolog-parse-sicstus-compilation-errors): Remove function, not used any more.
* lisp/image-dired.el (image-dired-toggle-dired-display-properties)
(image-dired--on-file-in-dired-buffer)
(image-dired-thumbnail-set-image-description)
(image-dired-mark-tagged-files)
(image-dired-dired-edit-comment-and-tags)
(image-dired-modify-mark-on-thumb-original-file): Don't end messages
with "." to better comply with '(elisp) Programming Tips'.
* 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.
