and its lock status either via _gtk_widget_get_accel_path() or by

action now, only set the accel_path on the menuitem.

the menuitem.

proxies. Don't set the accel group on created menus. For
NODE_TYPE_ACCELERATOR nodes, [dis]connect the actions' accelerator.
(print_node): Also emit <accelerator> elements.
* tests/testmerge.c (dump_accels): Add a "Dump Accels" button.
* gtk/gtkuimanager.c (update_smart_separators): New function which
implements "smart" separators by iterating once over the entries of a
menu, hiding and showing separators as necessary.
(update_node): Mark separators used as fences of placeholders as
hidden. Explicitly added separators are marked as smart. Call
update_smart_separators after updating a menu or toolbar node.
Connect update_smart_separators to "notify::visible" signal on menu
and tool items.
