* src/dispextern.h (struct image_type): Add new slot, storing a type
initialization function.
* src/image.c (define_image_type): Call the image initializer function
if it is defined. Arguments and return value changed.
(valid_image_p, make_image): Callers changed.
(xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
(gif_type, imagemagick_type, svg_type, gs_type): Add
initialization functions.
(Finit_image_library): Call lookup_image_type.
(CHECK_LIB_AVAILABLE): Macro deleted.
(lookup_image_type): Call define_image_type here, rather than via
Finit_image_library, and without using CHECK_LIB_AVAILABLE.
(syms_of_image): Move define_image_type calls for xbm_type and
pbm_type to lookup_image_type.
src/keyboard.c (timer_check_2): Move calculation of 'timers' and
'idle_timers' from here ...
(timer_check): ... to here. Use Fcopy_sequence to copy the timer
lists, to avoid infloops when the timer does something stupid,
like reinvoke itself with the same or smaller time-out.
lisp/emacs-lisp/timer.el (run-with-idle-timer)
(timer-activate-when-idle): Warn against reinvoking an idle timer
from within its own timer action.
doc/lispref/os.texi (Idle Timers): Warn against reinvoking an idle timer
from within its own timer action.
* window.c (Fsplit_window_internal): Handle only Qt value of
Vwindow_combination_limit separately.
(Qtemp_buffer_resize): New symbol.
(Vwindow_combination_limit): New default value. Rewrite
doc-string.
* cus-start.el (window-combination-limit): Add new optional
values.
* window.el (temp-buffer-window-show)
(window--try-to-split-window): Obey new values of
window-combination-limit.
(split-window): Test window-combination-limit for t instead of
non-nil.
(display-buffer-at-bottom): New buffer display action function.
* help.el (temp-buffer-resize-regexps): New option.
(temp-buffer-resize-mode): Rewrite doc-string.
(resize-temp-buffer-window): Obey temp-buffer-resize-regexps.
Don't resize reused window. Suggested by Glen Morris.
src/xdisp.c (next_overlay_string): Initialize it->end_charpos for
the new overlay string. Otherwise, the call to composition_compute_stop_pos
in compute_stop_pos uses a wrong it->end_charpos value, and crashes because
it runs off the end of the overlay string.
(rst-official-version)
(rst-package-emacs-version-alist): Sync with official version
V1.4.0.
(rst-faces-defaults, rst-set-level-default)
(rst-level-face-max, rst-level-face-base-color)
(rst-level-face-base-light, rst-level-face-format-light)
(rst-level-face-step-light, rst-define-level-faces): Obsolete.
(rst-adornment-faces-alist): Match new setup.
(rst-level-1, rst-level-2, rst-level-3, rst-level-4)
(rst-level-5, rst-level-6): New faces.
of `read-from-minibuffer' when `regexp-flag' is non-nil.
(occur-read-primary-args): Use `read-regexp' instead of
`read-string'.
(multi-occur-in-matching-buffers): Use `read-regexp' instead of
`read-from-minibuffer'.
* lisp/isearch.el (isearch-occur): Use `read-regexp' instead of
`read-string'.
* lisp/dired.el (dired-read-regexp): Use `read-regexp' instead of
`read-from-minibuffer'.
* lisp/progmodes/grep.el (grep-read-regexp): Use `read-regexp' instead
of `read-string'.
Fixes: debbugs:7567
(macroexp--expand-all): Use it.
(macroexp--funcall-and-return): Remove by folding it into its sole
caller (macroexp--warn-and-return).
* lisp/emacs-lisp/bytecomp.el (byte-compile-warn-obsolete):
Use macroexp--obsolete-warning.
calling mark_vectorlike since that's the one that marks the window.
(mark_discard_killed_buffers): Mark the final cdr.
* src/window.h (struct window): Move prev/next_buffers to the
non-standard fields.
* src/window.c (make_window): Initialize prev/next_buffers manually.
