 src/xdisp.c (Fmove_point_visually): When under word-wrap, accept
 also return value of MOVE_POS_MATCH_OR_ZV from
 move_it_in_display_line_to, when moving from beginning of line to
 point's position.

* buffer.c (Vbuffer_list_update_hook): Doc-string fix.
* window.c (Fselect_window): Explain NORECORD and
`buffer-list-update-hook' in doc-string.
* buffers.texi (The Buffer List): Rename node to Buffer List.
Describe `buffer-list-update-hook'.
* elisp.texi (Top): "The Buffer List" renamed to "Buffer List".
Add node for Window Dividers.
* hooks.texi (Standard Hooks): Add reference to
`buffer-list-update-hook'.
* windows.texi (Selecting Windows): Update description of
`select-window'.

* window.c (Fother_window_for_scrolling): Check that
Vother_window_scroll_buffer is a buffer.
* window.el (fit-frame-to-buffer, fit-frame-to-buffer-margins):
Fix doc-strings.
(fit-frame-to-buffer): New argument ONLY.  Remove dependency on
fit-frame-to-buffer variable.  Fix doc-string.
(fit-window-to-buffer): Set ONLY argument in call of
fit-frame-to-buffer.  Fix doc-string.
* frames.texi (Size and Position): Rewrite entries for
`fit-frame-to-buffer' and `fit-frame-to-buffer-margins'.  Add
description for `fit-frame-to-buffer-sizes'.
* windows.texi (Resizing Windows): Add descriptions for
pixelwise resizing.  Add entries for `window-resize-pixelwise'
and `fit-window-to-buffer-horizontally'.  Rewrite
`fit-window-to-buffer' entry.

to XRegisterIMInstantiateCallback and eassert whether return
value is True.  Passing copy is important because Xlib doesn't
make its own copy and resource name argument usually points to
SSDATA (Vx_resource_name), which may be changed from Lisp.
(xim_close_display): For XUnregisterIMInstantiateCallback,
always eassert return value and pass exactly the same values
as were used for XRegisterIMInstantiateCallback.  Otherwise
XUnregisterIMInstantiateCallback will always fail.  See Xlib
sources to check why if you are interested.

* dispnew.c (change_frame_size_1): Add new_lines instead of
new_height, the latter may be still zero if passed as such.
* window.c (Fwindow_pixel_height): Mention bottom divider in
doc-string.
* window.el (window-min-height, window-min-width): Rewrite
doc-strings.
(window-body-size): Add PIXELWISE argument to make it consistent
with its callees.
* display.texi (Window Dividers): New section.
* frames.texi (Layout Parameters): Add right-divider-width and
bottom-divider-width.
* windows.texi (Window Sizes): Redraw schematic and rewrite its
description.  Rewrite descriptions of `window-total-height',
`window-total-width', `window-total-size', `window-body-height',
`window-body-width' and `window-size-fixed'.  Add descriptions
for `window-pixel-height', `window-pixel-width',
`window-min-height' and `window-min-width'.  Remove description
of `window-size-fixed-p' moving part of it to that of
`window-size-fixed'.
(Resizing Windows): Mention dividers when talking about minimum
sizes.

* xgselect.c: Include <stdbool.h>.
(xg_select) [!USE_GTK]: Don't lose track of errno.

Fixes: debbugs:16925

* widget.c (update_various_frame_slots, EmacsFrameResize):
Avoid unused locals.  Prefer 'if' to '#if' when either will do.

* src/gmalloc.c (aligned_alloc): Clarify the code by making `adj'
represent the actual adjustment needed for alignment.

 src/gmalloc.c (aligned_alloc): Don't allocate more memory than
 needed, and don't reallocate if the initial allocation already
 fits the bill.  Suggested by Ken Brown <kbrown@cornell.edu>.

Fixes: debbugs:16901

* lisp/simple.el (delete-forward-char): Mark as interactive-only.
* src/cmds.c (delete-char): Update docstring pointing out that the
function ignores `delete-active-region' and `overwrite-mode'.

 src/font.c (Fframe_font_cache): Fix last change.

 src/gmalloc.c (aligned_alloc): Fix adjustment of size of the
 allocated buffer due to alignment.
 (freehook): If the block to be freed was allocated by
 'aligned_alloc', find its real pointer before calling 'free'.
 (mabort) [emacs]: Call 'emacs_abort', not 'abort', to provide a
 backtrace.

Fixes: debbugs:16901

'Display *' connection data (Bug#16069).  Note that X font
resources still may be leaked, but currently there is no way
to completely avoid it.
* xterm.h (struct x_display_info): New member x_id.  Add comments.
* xterm.c (x_display_id): New variable.
(x_term_init): Assign identifier to each opened X connection.
* xfont.c (struct xfont): New member x_display_id.
(xfont_open): Initialize it with frame's display id.
(xfont_close): Check whether font's display id matches the one
recorded for the given display.  Adjust comment.
* xftfont.c (struct xftfont_info):
(xftfont_open, xftfont_close): Exactly as above with xfont stuff.

(font_clear_cache): Fix to match real font cache layout.
Suggested by <namespace_collision@yahoo.com> in Bug#16069.
(Fframe_font_cache) [FONT_DEBUG]: New function.
(syms_of_font) [FONT_DEBUG]: Defsubr it.

* window.c (Fother_window_for_scrolling): Don't try to scroll a
killed Vother_window_scroll_buffer.
(Vother_window_scroll_buffer): Fix doc-string accordingly.

 src/fileio.c (Fexpand_file_name) [WINDOWSNT]: Don't treat file names
 that start with more than 2 slashes as UNCs.

* alloc.c, lisp.h (dupstring): New function.
* gtkutil.c (xg_get_font):
* term.c (tty_default_color_capabilities):
* xsettings.c (store_monospaced_changed)
(store_font_name_changed, parse_settings)
(read_and_apply_settings, init_gsettings, init_gconf): Use it.
This avoids some unlikely crashes due to accessing freed storage,
and avoids some minor memory leaks in the more-typical case.

* xdisp.c (note_mode_line_or_margin_highlight): Don't show drag
cursor when modeline can't be dragged (Bug#16647).

from custom-delayed-init-variables.

More fixes for mouse glyph calculations (Bug#16647).
* window.c (coordinates_in_window): In intersection of
horizontal and vertical window dividers prefer the horizontal
one.  Add some extra parens to last fix.
(window_relative_x_coord): Return x-coordinate for header and
mode line too.
* xdisp.c (remember_mouse_glyph): In text area don't extend
glyph into mode line to show the vertical drag cursor there
immediately.  Subdivide mouse glyphs in right fringes to show a
horizontal drag cursor as soon as we enter the "grabbable width"
portion.  Handle vertical border case separately.  Do not
subdivide window divider areas.
(note_mouse_highlight): On bottom divider of bottommost windows
show vertical drag cursor only when the minibuffer window can be
resized.

 src/xdisp.c (pop_it): Restore the it->face_box_p flag which could be
 reset by the face of the object just displayed.  See also bug#76.
 (get_next_display_element): If the string came from a display
 property, examine the box face attribute at it->position, not at
 it->current.pos, since the latter was not updated yet.
 (handle_face_prop): Improve commentary.

Rename from Fdbus_init_bus_1, Qdbus_init_bus_1, Sdbus_init_bus_1.

* xdisp.c (remember_mouse_glyph): Handle ON_RIGHT_DIVIDER and
ON_BOTTOM_DIVIDER cases.
* window.c (coordinates_in_window): Return ON_VERTICAL_BORDER
only if the window has no right divider.
(Fcoordinates_in_window_p): Fix doc-string.

* src/frame.c (frame-alpha-lower-limit, frame-resize-pixelwise):
* src/window.c (window-resize-pixelwise): Doc fixes.

* etc/NEWS: Related edits.
This including unmarking some items marked as ---, where it it not
clear to me that no doc updates are needed.

* src/process.c (Finternal_default_process_filter)
(Finternal_default_process_sentinel): Doc tweaks.

* doc/lispref/processes.texi: Typo fixes.

* etc/NEWS: Related markup.

* doc/lispref/internals.texi (Process Internals):
* doc/lispref/processes.texi (Deleting Processes, Output from Processes)
(Process Buffers, Filter Functions, Accepting Output, Sentinels)
(Network, Network Servers, Network Processes, Serial Ports):
Filters and sentinels can no longer be nil.

* doc/lispref/elisp.texi (Top): Menu update.

* doc/misc/flymake.texi (Starting the syntax check process): Grammar fix.

* doc/misc/tramp.texi (External packages): Grammar fix.
Reword for default sentinel not being nil any more.

* src/process.c (Fprocess_buffer, Faccept_process_output)
(Finternal_default_process_filter, Finternal_default_process_sentinel):
Doc fixes.

* window.el (window--dump-window, window--dump-frame): New
functions.
(window--min-size-1): Account for window dividers.  When
window-resize-pixelwise is nil, delay rounding till after the
sum of the window components has been calculated.
(window--min-delta-1, window--max-delta-1): When PIXELWISE is
nil make sure at least one text line and two text columns remain
fully visible.
(window-resize): Signal an error when window-resize-apply fails.
(window--resize-child-windows): Fix calculation of by how many
pixels a window can still be shrunk via window-new-normal.
(adjust-window-trailing-edge): Call window--resizable with
correct TRAIL argument.

* xdisp.c (move_it_in_display_line_to) [lint]:
Initialize recently-added local.

 src/xdisp.c (move_it_in_display_line_to): Save the iterator state in ppos_it
 only once per call.  Reimplement the method used to return to the
 best candidate position if all the positions found in display line
 are beyond TO_CHARPOS.  This cuts down the number of calls to
 bidi_shelve_cache, which moves a lot of stuff when lines are long
 and include bidirectional text.

 src/xdisp.c (try_cursor_movement): Don't use cursor position if
 set_cursor_from_row failed to compute it.  This avoids assertion
 violations in MATRIX_ROW.

 src/xdisp.c (init_iterator): Don't dereference a bogus face
 pointer.

* doc/lispref/functions.texi (Defining Functions):
Mention defalias-fset-function.

* src/data.c (Fdefalias): Doc fix.

* etc/NEWS: Related edit.

 src/xdisp.c (display_line): Fix horizontal scrolling of large images
 when fringes are turned off.  This comes at a price of not
 displaying the truncation/continuation glyphs in this case.

 src/image.c (x_create_x_image_and_pixmap) [HAVE_NTGUI]: If
 CreateDIBSection returns an error indication, zero out *ximg after
 destroying the image.  This avoids crashes in memory allocations
 due to the fact that some of the callers also call
 x_destroy_x_image, which will attempt to free an already free'd
 block of memory.

* widget.c (update_various_frame_slots): Don't set
FRAME_PIXEL_HEIGHT and FRAME_PIXEL_WIDTH here (Bug#16736).

* emacs.c (main): Initialize daemon_pipe[1] here ...
(syms_of_emacs): ... instead of here.
