	* gtk/gtktreeview.c (gtk_tree_view_header_focus): Fix up focus
	code a lot.

	* gtk/gtktreedatalist.c (_gtk_tree_data_list_free): use
	g_mem_chunk.
	(_gtk_tree_data_list_alloc): use g_mem_chunk.
	(_gtk_tree_data_list_node_to_value): Fix to switch on
	G_TYPE_FUNDAMENTAL.
	(_gtk_tree_data_list_value_to_node): Fix to switch on
	G_TYPE_FUNDAMENTAL.
	(_gtk_tree_data_list_node_copy): Fix to switch on
	G_TYPE_FUNDAMENTAL.
