Try to match an off toggle here with the matching on toggle if it

	* gtk/gtktextbtree.c (_gtk_text_btree_delete): Try to match an off
	toggle here with the matching on toggle if it immediately follows.
	This is a common case, and handling it here prevents quadratic blowup
	in cleanup_line() below.  (#317125)

	* gtk/gtktextsegment.h:
	* gtk/gtktextsegment.c (_gtk_char_segment_new_from_two_strings): Pass
	the character counts into this function instead of computing them
	again.
