	other event types.
	* lisp.h (Qvertical_scrollbar): Declare this.
	* window.c (window_from_scrollbar): New function.

	* xterm.h (struct x_display): Delete v_scrollbar, v_thumbup,
	v_thumbdown, v_slider, h_scrollbar, h_thumbup,
	h_thumbdown, h_slider, v_scrollbar_width, h_scrollbar_height
	* keyboard.c (Qvscrollbar_part, Qvslider_part, Qvthumbup_part,
	Qvthumbdown_part, Qhscrollbar_part, Qhslider_part, Qhthumbup_part,
	Qhthumbdown_part, Qscrollbar_click): Deleted; part of an obsolete
	(head_table): Removed from here as well.
	(syms_of_keyboard): And here.
	* keyboard.h: And here.
	* xscrollbar.h: File removed - no longer necessary.
	* xfns.c: Don't #include it any more.
	(Qhorizontal_scroll_bar, Qvertical_scroll_bar): Deleted.
	(syms_of_xfns): Don't initialize or staticpro them.

	* xterm.c (construct_mouse_click): This doesn't need to take care of
	scrollbar clicks anymore.
	(XTread_socket): Remove old code to support scrollbars.  Call new
	functions instead for events which occur in scrollbar windows.
	(XTupdate_end): Remove call to adjust_scrollbars; the main
	redisplay code takes care of that now.
	(enum window_type): Deleted.
	* ymakefile: Note that xfns.o no longer depends on xscrollbar.h.

	* keyboard.c (Fread_key_sequence): Doc fix.

	* keyboard.c (make_lispy_event): Buttons are numbered starting
	with zero now.

	* keyboard.c (make_lispy_event): Use the proper accessors when
	manipulating the `x' and `y' fields of struct input_event.

	* keyboard.c (parse_modifiers_uncached): Remember that strncmp
	returns zero if the two substrings are equal.

	* keyboard.c (do_mouse_tracking, Ftrack_mouse): Doc fix.

	* keyboard.c (read_char): Don't put mouse movements in

	Change the meaning of focus redirection to make switching windows
	work properly.  Fredirect_frame_focus has the details.
	* frame.h (focus_frame): Doc fix.
	[not MULTI_FRAME] (FRAME_FOCUS_FRAME): Make this Qnil, which
	indicates no focus redirection, instead of zero, which is
	* frame.c (make_frame): Initialize f->focus_frame to Qnil, rather
	than making it point to frame itself.
	(Fselect_frame): If changing the selected frame from FOO to BAR,
	make all redirections to FOO shift to BAR as well.  Doc fix.
	(Fredirect_frame_focus): Doc fix.  Accept nil as a valid
	redirection, not just as a default for FRAME.
	(Fframe_focus): Doc fix.
	* keyboard.c (kbd_buffer_store_event, kbd_buffer_get_event): Deal
	with focus redirections being nil.

	(kbd_buffer_get_event): When we remove an event from kbd_buffer,
	make sure to set the corresponding element of kbd_buffer_frames to
	Qnil, to allow the frame to get GC'd.
	(Fdiscard_input, init_keyboard): Clear all elements of
	kbd_buffer_frames to nil.

The interrupt-level event handlers will never enqueue a frame which

Vlast_event_frame or the event itself points to the frame. So
that's all fine.
But while the event is sitting in the queue, it's completely
unprotected. Suppose the user types one command which will run for
a while and then delete a frame, and then types another event at
the frame that will be deleted, before the command gets around to
it. Suppose there are no references to this frame elsewhere in
Emacs, and a GC occurs before the second event is dequeued. Now we
have an event referring to a freed frame, which will crash Emacs
when it is dequeued.

A C-g typed while in this function is treated like any other character,
and `quit-flag' is not set.
If the key sequence starts with a mouse click, then the sequence is read
using the keymaps of the buffer of the window clicked in, not the buffer
of the selected window as normal.
`read-key-sequence' drops unbound button-down events, since you normally
only care about the click or drag events which follow them. If a drag
event is unbound, but the corresponding click event would be bound,
`read-key-sequence' turns the drag event into a click event at the
drag's starting position. This means that you don't have to distinguish
between click and drag events unless you want to.
`read-key-sequence' prefixes mouse events on mode lines, the vertical
lines separating windows, and scrollbars with imaginary keys
`mode-line', `vertical-line', and `vertical-scrollbar'.
If the user switches frames in the middle of a key sequence, the
frame-switch event is put off until after the current key sequence.
`read-key-sequence' checks `function-key-map' for function key
sequences, where they wouldn't conflict with ordinary bindings. See
