	FRAME_VAR is a lisp object.
	* dispnew.c (WINDOW_CHANGE_SIGNAL, do_pending_window_change):
	Adjusted appropriately.
	* xdisp.c (redisplay): Adjusted appropriately.

	* dispnew.c (Fredraw_frame): Give this appropriate definitions for
	MULTI_FRAME and non-MULTI_FRAME configurations.
	(Fredraw_display): Give this a non-MULTI_FRAME-dependent definition.

Fill out line with spaces.
Put explicit spaces between items.

(redisplay_window): Call display_menu_bar.

(copy_part_of_rope): New function.
(display_string): Expect display table elts to be vectors.

	unrequest_sigio in "#ifdef SIGIO" clauses; these are not defined

	Use the term `scroll bar', instead of `scrollbar'.
	* alloc.c, frame.c, frame.h, indent.c, keyboard.c, keyboard.h,
	lisp.h, term.c, termhooks.h, window.c, window.h, xdisp.c, xfns.c,
	xterm.c, xterm.h: Terminology changed.

	we want to use, not to the message buf itself.

	* xdisp.c (message): Use the message buffer of the frame we're
	going to display the message on to format the message, not that of
	the selected frame.

	for scrollbars if present.
	* lisp.h (window_internal_height, window_internal_width): Add
	extern declarations for these.
	* dispnew.c (direct_output_for_insert, direct_output_forward_char,
	buffer_posn_from_coords): Use window_internal_width instead of
	writing out its definition.
	* indent.c (compute_motion): Doc fix; mention scrollbars and
	window_internal_width.
	(pos_tab_offset, Fvertical_motion): Use window_internal_width
	instead of writing it out.
	* window.c (Fpos_visible_in_window_p, Fwindow_width, Fscroll_left,
	Fscroll_right): Same.
	* xdisp.c (redisplay, try_window, try_window_id,
	display_text_line): Same.

	* xdisp.c (display_string): Add new variable `f', to be W's
	frame.  Use it to set desired_glyphs, and to get the frame's width
	to decide whether or not to draw vertical bars.

	* xdisp.c (display_text_line): If we're using vertical scrollbars,
	don't draw the vertical bars separating side-by-side windows.
	(display_string): Same thing.  Draw spaces to fill in the part of
	the mode line that is under the scrollbar in partial-width
	windows.

	* xdisp.c (display_text_line): Use the usable internal width of
	the window, as calculated above, as the limit on the length of the
	overlay arrow's image, rather than using the window's width field,
	less one.

	* xdisp.c (redisplay): Call condemn_scrollbars_hook and
	judge_scrollbars_hook whenever they are set, not just when the
	frame has vertical scrollbars.

	* termhooks.h (mouse_position_hook): Doc fix.
	(set_vertical_scrollbar_hook): This doesn't return anything any
	more, and doesn't take a struct scrollbar * argument any more.
	(condemn_scrollbars_hook, redeem_scrollbar_hook,
	judge_scrollbars_hook): Doc fixes.
	* term.c (mouse_position_hook): Doc fix.
	(set_vertical_scrollbar_hook): This doesn't return
	anything any more.  Doc fixes.
	* keyboard.c (kbd_buffer_get_event): Receive the scrollbar's
	window from *mouse_position_hook and pass it to
	make_lispy_movement, instead of working with a pointer to a struct
	scrollbar.
	(make_lispy_event): We don't need a window_from_scrollbar function
	anymore; we are given the window directly in *EVENT.
	Unify the code which generates
	text-area mouse clicks and scrollbar clicks; use the same code to
	distinguish clicks from drags on the scrollbar as in the text area.
	Distinguish clicks from drags by storing a copy of the lispy
	position list returned as part of the event.
	(button_down_location): Make this a lisp vector, rather than an
	array of random structures.
	(struct mouse_position): Remove this; it's been replaced by a lisp
	list.
	(make_lispy_movement): Accept the scrollbar's window as a
	parameter, rather than the scrollbar itself.
	If FRAME is zero, assume that the other arguments are garbage.
	(syms_of_keyboard): No need to staticpro each window of
	button_down_location now; just initialize and staticpro it.
	* window.c (window_from_scrollbar): Function deleted; no longer
	needed.
	* xdisp.c (redisplay_window): Just pass the window to
	set_vertical_scrollbar hook; don't pass the scrollbar object too.
	* xterm.c (XTmouse_position): Don't return a pointer to the
	scrollbar for scrollbar motion; instead, return the scrollbar's
	window.

	* xdisp.c (echo_area_display): Move the assignment of f and the
	check for visibility out of the "#ifdef MULTI_FRAME" clause; they
	should work under any circumstances.

	* xdisp.c (redisplay_window): If we're not going to redisplay this
	window because it's a minibuffer whose contents have already been
	updated, go ahead and jump to the scrollbar refreshing code
	anyway; they still need to be updated.  Initialize opoint, so it's
	known to be valid when we jump.  Calculate the scrollbar settings
	properly for minibuffers, no matter what they are displaying at
	the time.

	* xdisp.c (redisplay_windows): Don't restore the current buffer
	and its point before refreshing the scrollbars; we need the buffer
	accurate.

	(redisplay, redisplay_window): Use set_vertical_scrollbar_hook,
	condemn_scrollbars_hook, redeem_scrollbar_hook, and
	judge_scrollbars_hook to make scrollbars redisplay properly.

	It's a pain to remember that you can't assign to FRAME->visible.
	Let's change all references to the `visible' member of struct
	frame to use the accessor macros, and then write a setter for the
	`visible' field that does the right thing.
	* frame.h (FRAME_VISIBLE_P): Make this not an l-value.
	(FRAME_SET_VISIBLE): New macro.
	* frame.c (make_terminal_frame, Fdelete_frame): Use FRAME_SET_VISIBLE.
	(Fframe_visible_p, Fvisible_frame_list): Use FRAME_VISIBLE_P and
	FRAME_ICONIFIED_P.
	* dispnew.c (Fredraw_display): Use the FRAME_VISIBLE_P and
	FRAME_GARBAGED_P accessors.
	* xdisp.c (redisplay): Use the FRAME_VISIBLE_P accessor.
	* xfns.c (x_set_foreground_color, x_set_background_color,
	x_set_cursor_color, x_set_border_pixel, x_set_icon_type): Use the
	FRAME_VISIBLE_P accessor.
	(Fx_create_frame): Use FRAME_SET_VISIBILITY.
	* xterm.c (clear_cursor, x_display_bar_cursor,
	x_display_box_cursor): Use FRAME_SET_VISIBILITY.

	visible and iconified flags appropriately for each frame.
	(message1): Call FRAME_SAMPLE_VISIBILITY to set the visible and
	iconified flags for the minibuffer frame.

	* xdisp.c (redisplay): Use FOR_EACH_FRAME to apply
	redisplay_windows to the root window of each frame.  This makes a
	#ifdef MULTI_FRAME unneeded, but it also means we recompute
	buffer_shared from scratch even on non-MULTI_FRAME configurations.
	Don't skip elements of Vframe_list that aren't frames; go ahead
	and crash here.

	* xdisp.c (redisplay): Remove #ifdef MULTI_FRAME around the code
	which updates separate minibuffer frames specially; there's
	nothing there that won't work on a single-frame configuration.

	tab-width to display the string, instead of the current buffer's,
	which could be anything.

	positions, not !=.
	(mark_window_display_accurate): Barf if WINDOW isn't a window.
	(display_string): Test buffer_defaults.ctl_arrow using NILP,
	instead of comparing it with zero.

	* xdisp.c (last_arrow_position, last_arrow_string): Make these
	static.

	* xdisp.c (message): Re-write this in terms of message1.
	(message1): Move code to clear out echo_area_glyphs and
	previous_echo_glyphs from message to here.

	previous_echo_glyphs, so that the minibuffer shows through.

	minibuffer frames, don't name the frame after the in the selected
	window.  We can use Fnext_frame to do this test easily.

	* xdisp.c (redisplay, init_xdisp): Use FRAME_ROOT_WINDOW instead
	of minibuf_window->prev.

	* xdisp.c (decode_mode_spec): Move lots_of_dashes outside of the
	function; Emacs can't use static initialized arrays inside functions.

	Renamed these to FRAME_TERMCAP_P, FRAME_X_P, and
	FRAME_HAS_MINIBUF_P, for consistency with the rest of the
	frame macros.
