	window rectangle for the given fullscreen mode.

	window decorations and uses the entire screen.

	* w32term.h  (w32_fullscreen_rect) Add prototype.

	normal_top, and normal_left members with a single normal_placement

	* indent.c (Fvertical_motion): Don't consider display strings on
	overlay strings as display strings on the buffer position we
	started from.  This prevents vertical cursor motion from jumping
	more than one line when there's an overlay string with a display
	property at end of line.
	Reported by Karl Chen <Karl.Chen@quarl.org> in

	* window.c (Fwindow_end): Test more flags, including the buffer's
	last_overlay_modified flag, to determine whether the window's
	display is really up-to-date.  Prevents the function from
	returning a stale value.  (Bug#14170)
	(Fwindow_line_height): Fix the test for up-to-date-ness of the
	current matrix.

2013-04-10  Eli Zaretskii  <eliz@gnu.org>

	* frame.c (do_switch_frame): Mark the TTY frame we switch to as
152 153
	garbaged only if it is not already the top frame on its TTY.
	This prevents flickering due to constant redrawing of TTY frames when
154 155
	there are GUI frames open in the same session.  (Bug#13864)

	Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
	This bug was introduced by my 2013-02-25 change that simplified
	data_start configuration.  Without this change, on GNU/Linux
	an Emacs configured with --enable-profiling fails immediately
	due to a profiler signal.
	* Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
	with these flags.  On platforms where special flags are needed
	when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.

	(.c.o, .m.o): Compile with $(PROFILING_CFLAGS).

2013-04-02  Paul Eggert  <eggert@cs.ucla.edu>

	Prefer < to > in range checks such as 0 <= i && i < N.

	* window.h (struct window): Replace hchild, vchild and buffer slots
	with the only contents slot.  This is possible because each valid
	window may have either the child window (in vertical or horizontal
	combination) or buffer to display (for the leaf window).  Using that,
	a lof of operations to traverse and/or change window hierarchies may
	be simplified.  New member horizontal is used to distinguish between
	horizontal and vertical combinations of internal windows.

	(mark_window_cursors_off, count_windows, get_leaf_windows)
	(foreach_window_1): Simplify the loop.
	* alloc.c (mark_object): Do not check for the leaf window because
	internal windows has no glyph matrices anyway.
	* dispnew.c (clear_window_matrices, showing_window_margins_p)
	(allocate_matrices_for_window_redisplay, fake_current_matrices)

	(update_window_tree, set_window_update_flags): Simplify the loop.
	(sync_window_with_frame_matrix_rows): Enforce live window.

	and WINDOW_HORIZONTAL_COMBINATION_P.

	(MAX_LFINFO): New top-level constant.
	(lock_info_type): Remove members pid, boot_time.  Add members at,
	dot, colon.  Change user member to be the entire buffer, not a

	pid or boot time exceeds the local range.  All uses changed.

	(rename_lock_file): New function.
	(create_lock_file): Use it.
	(create_lock_file, read_lock_data):
	Prefer a symbolic link for the lock file, falling back on a
	regular file if symlinks don't work.  Do not try to create
	symlinks on MS-Windows, due to security hassles.  Stick with
	POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
	link, rename, unlink, mkstemp) when creating locks, as a GNUish
	host may be using a Windowsish file system, and cannot use
	MS-Windows-only system calls.  Fall back on mktemp if mkstemp
	doesn't work.  Don't fail merely because of a symlink-contents
	length limit in the current file system; fall back on regular
	files.  Increase the symlink contents length limit to 8 KiB, this
	should be big enough for any real use and doesn't crunch the
	stack.
	(create_lock_file, lock_file_1, read_lock_data):
	Simplify allocation of lock file buffers now that they fit in 8 KiB.
	(lock_file_1): Return error number, not bool.  All callers changed.
	(ELOOP): New macro, if not already defined.
	(read_lock_data): Return size of lock file contents, not Lisp object.
	All callers changed.  Handle a race condition if some other process
	replaces a regular-file lock with a symlink lock or vice versa,
	while we're trying to read the lock.
	(current_lock_owner): Parse contents more carefully, to help avoid
	confusing a regular-file lock with some other application's use
	of the file.  Check for lock file contents being too long, or
	not parsing correctly.
	(current_lock_owner, lock_file):
	Allow foreign pid and boot times that exceed the local range.
	(current_lock_owner, lock_if_free, lock_file):
	Simplify allocation of lock file contents.

	(sys_rename): Use it.
	(fchmod): New dummy function.

2013-03-02  Paul Eggert  <eggert@cs.ucla.edu>

	The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
	The old approach, which fell back on DIR/.#FILE.0 through
	DIR/.#FILE.9, had race conditions that could not be easily fixed.
	If DIR/.#FILE is a non-symlink file, Emacs now does not create a
	lock file for DIR/FILE; that is, DIR/FILE is no longer partly
	protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
	because the locking mechanism was never reliable in that case).
	This patch fixes this and other bugs discovered by a code
	inspection that was prompted by
	<http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
	Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
	to avoid interoperability problems between the MS-Windows and
	non-MS-Windows implementations.  MS-Windows and non-MS-Windows
	instances of Emacs now ignore each others' locks.
	* filelock.c (defined_WINDOWSNT): New constant.
	(MAKE_LOCK_NAME, fill_in_lock_file_name):
	Don't create DIR/.#FILE.0 through DIR/.#FILE.9.  Instead, create
	DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
	regular files on MS-Windows hosts.
	(MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
	Use SAFE_ALLOCA to avoid problems with long file names.
	(MAX_LFINFO): Now a local constant, not a global macro.
	(IS_LOCK_FILE): Remove.
	(lock_file_1): Don't inspect errno if symlink call succeeds;
	that's not portable.

	* xdisp.c (redisplay_internal): Don't set w->region_showing to the
	marker's position.
	(display_line): Set w->region_showing to the value of
	it->region_beg_charpos, not to -1.  This fixes redisplay
	optimization when cursor is moved up after M->.  (Bug#13623)
	(Bug#13626)
1574 1575 1576
	(try_scrolling): Scroll text up more if point is too close to ZV
	and inside the scroll margin.  This makes sure point is moved
	outside the scroll margin in these cases.
1577 1578 1579 1580

	* window.h (struct window): region_showing can no longer be
	negative.

	Tune by using memchr and memrchr.
	* doc.c (Fsnarf_documentation):
	* fileio.c (Fsubstitute_in_file_name):
	* search.c (find_newline, scan_newline):
	* xdisp.c (pos_visible_p, display_count_lines):
	Use memchr and memrchr rather than scanning byte-by-byte.
	* search.c (find_newline): Rename from scan_buffer.
	Omit first arg TARGET, as it's always '\n'.  All callers changed.

1592 1593 1594 1595
	Clean up read_key_sequence a tiny bit more.
	* keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
	(read_key_sequence): Remove unused locals.

	Clean up read_key_sequence a bit; reread active keymaps after first event.
	* keyboard.c (read_char, read_char_x_menu_prompt)
	(read_char_minibuf_menu_prompt):
	Replace nmaps+maps with a single `map' arg.
	(follow_key): Operate on a single map.
	(active_maps): New function.
	(test_undefined): Also return true for nil bindings.
	(read_key_sequence): Use active_maps to replace the arrays of keymaps with
	a single (composed) keymap.  Remember `first_event' to choose the right
	set of active keymaps.  Recompute the set of keymaps after receiving
	the first event.  Remove GOBBLE_FIRST_EVENT.
	(syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
	* keyboard.h (read_char): Update declaration.
	* lread.c (read_filtered_event): Adjust call to read_char.

	* xdisp.c (move_it_vertically_backward, move_it_by_lines):
	Don't use the limitation on backwards movement when lines are truncated
