	* gtk/gtktextview.c (gtk_text_view_move_cursor_internal): change
	GTK_MOVEMENT_PARAGRAPHS to go to start/end of paragraph before it
	starts to go up/down paragraphs. This makes Ctrl+Up/Ctrl+Down work
	as in the keynav spec, though it makes the interpretation of
	GTK_MOVEMENT_PARAGRAPHS different from the interpretation of some
	of the other GTK_MOVEMENT_ thingies, maybe, as if that enum makes
	any sense anyhow.
