just go ahead and flush all the first validate stuff if it hasn't been

	* gtk/gtktextview.c (gtk_text_view_paint): just go ahead and flush
	all the first validate stuff if it hasn't been done, presumably
	someone called process_updates at a weird time.

	* tests/testtext.c (do_apply_colors): terminate on >= end, not >
	end, avoids infinite loop when end is at the end of the buffer.

	* gtk/gtktextbtree.c (_gtk_text_btree_delete): when creating a
	line data, we were adding it to the wrong line ("line" instead of
	"start_line")
