Make logical motion and deletion by graphemes, not by characters.

	* gtk/gtkentry.c: Make logical motion and deletion by graphemes,
	not by characters.

	* gtk/gtkentry.c: Handle "trailing" returns from Pango when they
	are not zero or one; that is, when graphemes of multiple characters
	are involved.

	* gtk/gtktextlayout.c (line_display_index_to_iter): Remove unnecessary
	FIXME.
