* src/xterm.c (xm_read_drop_start_message): New function.
(xm_read_drag_motion_message): Check that the originator is
correct.
(x_coords_from_dnd_message): Read drop start messages as well.
This avoids an extra sync, which matters when dropping onto
Emacs running over a slow connection.
* src/xselect.c (x_handle_dnd_message): New args
`root_window_coords', `root_x' and `root_y'.
* src/xterm.c (x_coords_from_dnd_message): New function.
(handle_one_xevent): Pass root window coordinates to
x_handle_dnd_message.
* src/xterm.h: Update prototypes.
* src/xfont.c (xfont_list_pattern): Initialize a local.
Although I’m not sure this is needed, it doesn’t change
behavior (except possibly to make undefined behavior defined).
* lisp/x-dnd.el (x-dnd-test-function): Fix doc string to
describe what is actually accepted.
(x-dnd-known-types, x-dnd-targets-list): Fix coding style.
(x-dnd-handle-native-drop): New function.
* src/xselect.c (x_atom_to_symbol): Export.
* src/xterm.c (x_dnd_note_self_drop): Call new variable to
determine what action to return.
(x_clear_dnd_action): New function.
(x_dnd_begin_drag_and_drop): Respect new variable.
(syms_of_xterm): New defvar `x-dnd-native-test-function'.
* src/xterm.h: Update prototypes.
* src/xterm.c (x_dnd_update_tooltip_now): Add missing part of
last change.
(x_monitors_changed_cb, handle_one_xevent): Only update if a
change in monitor configuration really happened.
* src/xterm.c (x_dnd_note_self_drop): Set DND action to
XdndActionPrivate.
(x_dnd_begin_drag_and_drop): Don't return XdndPrivate specially
here.
(handle_one_xevent): Fix order of arguments to
x_dnd_note_self_drop.
* src/xdisp.c (update_redisplay_ticks): New function.
(init_iterator, set_iterator_to_next): Call
'update_redisplay_ticks'.
(syms_of_xdisp) <max_redisplay_ticks>: New variable.
<list_of_error>: Remove 'void-variable': it is no longer needed,
since 'calc_pixel_width_or_height' can no longer signal a
void-variable error, and it gets in the way of aborting
redisplay via 'redisplay_window_error'.
* src/xterm.c (x_dnd_cleanup_drag_and_drop)
(x_dnd_begin_drag_and_drop): Delete XdndTypeList if it was set
after the DND operation completes. Some programs apparently
think its presence on the drag source means there are more than
3 targets.
* src/xterm.c (x_dnd_get_target_window): New parameter
WAS_FRAME. If toplevel is a frame, set it and clear proto and
motif.
(x_dnd_send_enter, x_dnd_send_position, x_dnd_send_leave)
(x_dnd_send_drop): Remove special-cased self dropping code.
(x_dnd_note_self_position, x_dnd_note_self_drop): New functions.
(x_dnd_begin_drag_and_drop, x_dnd_update_state):
(handle_one_xevent): Handle our own frames using those functions
instead.
* doc/lispref/files.texi (Reading from Files): Document it.
* src/fileio.c (Finsert_file_contents): Allow specifying END for
special files (bug#18370).
* lisp/term/haiku-win.el (haiku-drag-and-drop): Don't raise
frame for some types of drags.
* src/haikuselect.c (haiku_unwind_drag_message): Don't hide
tooltip here.
(Fhaiku_drag_message): Only clear grab and hide tooltip if the
drag was successful.
* src/minibuf.c (Fcompleting_read):
* lisp/minibuffer.el (read-file-name):
* doc/lispref/minibuf.texi (Minibuffer Completion):
* etc/NEWS: Fix typos and wording of the description of the
REQUIRE-MATCH argument to 'completing-read'.
* doc/lispref/minibuf.texi (Minibuffer Completion): Document it.
* lisp/minibuffer.el (completion--complete-and-exit): Allow
REQUIRE-MATCH to be a function.
(read-file-name): Mention it.
* src/minibuf.c (Fcompleting_read): Mention it.
Previously it would only happen upon the next mode line
redisplay, meaning that just pressing C-z would not update the
implicit title, since C-z doesn't cause a redisplay.
* src/dispextern.h: Update prototypes.
* src/frame.h (SET_FRAME_ICONIFIED): De-slugify. Call
`gui_consider_frame_title', since `icon-title-format' might be
different from the current frame title.
* src/xdisp.c (gui_consider_frame_title): Export (also in
dispextern.h). (bug#55850)
* src/fns.c (Fline_number_at_pos): Allow calling with position
outside the region if called with ABSOLUTE non-nil (bug#55847).
This isn't announced in the doc string, but makes function
compatible with the version in earlier Emacs versions.
* lisp/term/ns-win.el (x-begin-drag): Pass `follow-tooltip'.
* src/nsfns.m (Fx_show_tip): Record last dx and dy.
(syms_of_nsfns): New staticpros.
* src/nsmenu.m ([EmacsTooltip moveTo:]): New method.
* src/nsselect.m (Fns_begin_drag): New parameter
`follow-tooltip'.
* src/nsterm.h (@interface EmacsWindow):
(EmacsTooltip): Update prototypes.
* src/nsterm.m ([EmacsWindow draggedImage:movedTo:]): Move any
tooltip to the right location.
([EmacsWindow beginDrag:forPasteboard...]): New parameter
`followTooltip'.
* lisp/mouse.el (mouse-drag-and-drop-region): Turn off system
tooltips inside.
* src/xfns.c (Fx_begin_drag): Say that follow-tooltip doesn't
work with system tooltips.
* lisp/term/haiku-win.el (x-begin-drag): Implement
`follow-tooltip'.
* src/haikufns.c (Fx_show_tip): Record last dx and dy.
(syms_of_haikufns): New staticpros.
* src/haikuselect.c (haiku_unwind_drag_message): Clear new flag.

flag.
(haiku_dnd_compute_tip_xy): New function.
(haiku_note_drag_motion): Move tooltip if flag is true.
* src/haikuterm.c (haiku_read_socket): Don't generate help event
if mouse moves onto a tooltip during DND.
* src/haikuterm.h: Update prototypes.
* src/window.h (window_body_unit): New enum...
(window_body_width): ... use it.
* src/window.c (window_body_unit_from_symbol): New function.
(window_body_height, window_body_width): Make PIXELWISE a
'window_body_unit'.
(window-body-height, window-body-width): Accept 'remap' for PIXELWISE.
(window-lines-pixel-dimensions, window_change_record_windows)
(run_window_change_functions, resize_frame_windows, grow_mini_window)
(shrink_mini_window, scroll-left, scroll-right): Update calls to
'window_body_height' and 'window_body_width'.
* src/indent.c (compute_motion): Update calls to 'window_body_width'.
* lisp/eshell/em-ls.el (eshell-ls-find-column-widths)
(eshell-ls-find-column-lengths): Use 'window-body-width'.
* lisp/eshell/esh-var.el (eshell-variable-aliases-list): Use
'window-body-width' and 'window-body-height'.
* test/lisp/eshell/esh-var-tests.el (esh-var-test/window-height)
(esh-var-test/window-width): Rename to...
(esh-var-test/lines-var, esh-var-test/columns-var): ... and update
expected value.
* doc/lispref/windows.texi (Window Sizes): Document new behavior of
PIXELWISE argument for 'window-body-width' and 'window-body-height'.
* etc/NEWS: Announce this change (bug#55696).
