	Fix #305737, patch from Tomislav Jonjic. This makes the
	gtk_tree_store_insert* family of functions emit row_has_child_toggled
	when needed (they didn't do that before).

	* gtk/gtktreestore.c (gtk_tree_store_insert): emit
	row_has_child_toggled when needed,
	(gtk_tree_store_insert_before): fix a possible memleak,
	emit row_has_child_toggled when needed,
	(gtk_tree_store_insert_after): ditto.
