if region is being highlighted.

(direct_output_for_insert): Pass those args.

	BUFFER argument has been omitted, put it in the current buffer,
	for symmetry with move-marker.

	* buffer.c (Fdelete_overlay): Make the overlay's markers point
	nowhere, not at 1.  Do this after calling redisplay_region, so
	that code knows what section has changed.

(store_in_keymap): Likewise.
(Fcopy_keymap): Likewise.

(isearch-char-to-string): Handle non-character events properly.

	Foverlay_properties): Functions moved here from subr.el.

	face specified by the glyph under it.

	* xterm.c (dumpglyphs): Move the underline up a row.  I dislike
	the way X addresses pixels.  Quickdraw is much nicer.

	* xterm.c (dumpglyphs): Pass the proper arguments to intern_face.

	* xterm.c (dumpglyphs): Don't increment left twice.

	traverse sortvec, not overlay_vec; the latter isn't the one we
	sorted.

	* xfaces.c (intern_face): If the face has a GC, but it's not the
	default or modeline face, abort.  Nothing but those two faces
	should have a GC *and* be passed to intern_face.
	(compute_char_face, compute_glyph_face): After copying
	the frame's default face into face, to use as a base case for
	calculation, set the `gc' member to zero; that way we don't have
	things lying around that look like display faces but aren't.

	* xfaces.c (intern_frame_face): When copying the new face into the
	frame's face array, remember that the number of bytes to copy is
	sizeof (*new_face), not sizeof (new_face).

	* xfaces.c (compute_char_face): Assume that W is displaying the
	current buffer.  Abort if it isn't.

	than the current one.
	* insdel.c (modify_region): New argument BUFFER.  Select that
	buffer while we prepare for the modification, and switch back when
	we're done.
	* textprop.c (add_properties, remove_properties): Pass
	the buffer being modified as the first argument to modify_region.
	* editfns.c (Fsubst_char_in_region, Ftranslate_region): Pass the
	current_buffer as the first argument to modify_region.
	* casefiddle.c (casify_region): Same.

	(Fdelete_overlay): Set the overlay's markers to point nowhere.
	Use CHECK_OVERLAY instead of signalling a special error.
	(Fmove_overlay, Foverlay_put): Use CHECK_OVERLAY instead of
	signalling a special error.
	(Foverlay_get): Use CHECK_OVERLAY.
	* fns.c (internal_equal): Define this for overlays.
	* buffer.h (OVERLAY_VALID): Define in terms of OVERLAYP.
	* print.c (print): Give overlays their own print syntax.
	* alloc.c (mark_object): Treat overlays like conses.

	POSIX.

	(OVERLAYP): New predicate.
	(CHECK_OVERLAY): New type-checker.
	(Qoverlayp): New extern declaration.
	* buffer.c (Foverlayp): New function.

	* print.c (print): Give overlays their own print syntax.
	* alloc.c (mark_object): Treat overlays like conses.

	is not defined.

	checking for an empty interval tree.

	set point, instead of setting point to a potentially invalid
	position.

	make callers correct.

	* xfaces.c (compute_char_face): Notice the next property change
	location correctly.

	* xfaces.c (face_name_id_number): Return 0 (the default face) if
	the name is undefined.

	* xfaces.c (Fset_face_attribute_internal): Do nothing unless FRAME
	is an X frame.

They are now called directly.

	Fprevious_single_property_change): Pass arguments to textget in
	the right order.
