Only shorten the label if it actually overlaps the resize grip.

2004-11-10  Matthias Clasen  <mclasen@redhat.com>

	* gtk/gtkstatusbar.c (gtk_statusbar_size_allocate): Only
	shorten the label if it actually overlaps the resize grip.
	(gtk_statusbar_size_allocate): Handle extra children
	by leaving room for the resize grip.  (#157778, Christian Persch)
