	(NUM_MOUSE_BUTTONS): New constant.
	(click_modifier): New modifier.
	(NUM_MODIFIER_COMBOS): Removed.

	are not 5 elements long.
	(EVENT_HEAD): Work correctly on all sorts of events, not just
	events with parameters.
	(EVENT_WINDOW, EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON,
	EVENT_WINDOW_POSN, EVENT_TIMESTAMP): These aren't useful
	anymore; this information may appear twice in an event.  These
	are replaced by the POSN_ accessors, which are meant to be
	composed with the EVENT_START and EVENT_END accessors.
	(EVENT_START, EVENT_END): Two new accessors, to get at the
	starting and ending position of an event.
	(POSN_WINDOW, POSN_BUFFER_POSN, PONS_SCROLLBAR_BUTTON,
	POSN_WINDOW_POSN, POSN_TIMESTAMP): New macros, to futher
	diasassemble the values returned by EVENT_START and EVENT_END.

	* keyboard.h (Qevent_unmodified): Extern declaration replaced by...
	(Qevent_symbol_elements): This.
	(EVENT_HEAD_UNMODIFIED): Use the Qevent_symbol_elements
	property, rather than the Qevent_unmodified property.

	testing for EVENT_HAS_PARAMETERS; EVENT_HEAD works properly on
	all sorts of events now.
	(read_key_sequence): Use the new accessors to decide in which window
	an event occurred.

	* keyboard.c (Qevent_unmodified): Replaced by...
	(Qevent_symbol_elements): New property.
	(syms_of_keyboard): initialize and staticpro the latter, not the
	former.

	* keyboard.c (readable_events): This doesn't need to scan and
	discard mouse release events anymore; it just uses
	EVENT_QUEUES_EMPTY.
	(kbd_buffer_get_event): No need to skip past mouse release events.

	* keyboard.c (button_down_location): New variable, which
	stores the location at which each button was pressed, so we
	can build a complete drag event when the button is released.
	(make_lispy_event): When a button is pressed, record its
	location in button_down_location, and turn it into a `down'
	event.  When a button is released, compare its release
	location with its press location, and decide whether to call
	it a `click' or `drag' event.
	Change mouse movement events to be arranged like click events.
	(format_modifiers): Note that the click modifier has no
	written representation.
	(modifier_names, modifer_symbols): New variables, used to
	create the Qevent_symbol_elements property.
	(modify_event_symbol): Change the format of the modified
	symbol cache; there are too many modifier bits now to use a
	vector indexed by a modifier mask.  Use an assoc-list instead.
	Document the format of the cache.
	Put the Qevent_symbol_elements property on each new symbol,
	instead of a Qevent_unmodified property.
	(symbols_of_keyboard): Put Qevent_symbol_elements properties on
	the symbols specified in head_table, not Qevent_unmodifed properties.
	Initialize and staticpro modifier_symbols, and staticpro the
	window elements of button_down_location.

Fix interactive spec.  Doc fix.  Put on mouse-3.

	(Fx_popup_menu): Use the event accessors defined in keyboard.h,
	instead of writing out cars and cdrs.

	"USE_TEXT_PROPERTIES".

	"USE_TEXT_PROPERTIES".

	(init_intervals, make_interval,
	mark_interval, mark_interval_tree): New functions conditionally
	defined.
	(make_uninit_string): Call INITIALIZE_INTERVAL.
	(INIT_INTERVALS, UNMARK_BALANCE_INTERVALS, MARK_INTERVAL_TREE):
	New macros, conditionally defined.
	(mark_object): Call MARK_INTERVAL_TREE in case Lisp_String.
	(gc_sweep): If text properties are in use, place all unmarked
	intervals on the free list.  Call UNMARK_BALANCE_INTERVALS on
	`buffer->intervals' when unmarking `buffer'.
	(compact_strings): Include INTERVAL_PTR_SIZE in calculation for
	target of bcopy when relocating strings.
	(init_alloc_once): Call INIT_INTERVALS.
	(make_pure_string): Include INTERVAL_PTR_SIZE in calculation of
	`size'.

	text was actually inserted.
	#include "intervals.h".

Avoid recursion on constants-vector of a compiled function.

looking-at call doesn't clobber its value when we want to use it to back up
before the error we discard.
Make sure compilation-error-list is at least two elts long before checking
its first two elts for being in the same file.

	interval component.
	(Fkill_buffer): Likewise.

	Add DECLARE_INTERVALS to struct Lisp_String.

	(prepare_to_modify_buffer): Call verify_interval_modification().
	(insert_from_string): Call offset_intervals() and
	graft_intervals_into_buffer().
	(del_range): Call offset_intervals().
	(insert): Call offset_intervals().

	and TEMP_SET_PT are function calls.
	Similarly for BUF_SET_PT and BUF_TEMP_SET_PT.
	Added DECLARE_INTERVALS to buffer structure to conditionally
	compile an interval tree into it..

	(Finsert_buffer_substring): Call graft_intervals_into_buffer().
	#include "intervals.h".

	got removed with no comment or ChangeLog entry, and
	append-to-buffer uses it.

	just because we restored its configuration.

	* window.c (Fset_window_configuration): Don't forget to set the
	frame's selected window when we can't call Fselect_window.

	modifier bits denote meta keys.
	(x_find_modifier_meanings): New function, to set x_meta_mod_mask.
	(x_convert_modifiers): Use that.
	(x_term_init): Call x_find_modifier_meanings.

	* xterm.c (XTread_socket): Pass PropertyNotify events from the
	root window to x_invalidate_cut_buffer_cache.
	(x_term_init): Call x_watch_cut_buffer_cache here.

	swap in the value for the current buffer immediately.

(delete-indentation): Don't go beyond eob, comparing with fill-prefix.
