Rob Adams 191b3f2c21 set on_all_workspaces in all cases _before_ adding to the workspaces, so 
2003-12-13  Rob Adams  <readams@readams.net>

	* src/window.c (meta_window_new_with_attrs): set on_all_workspaces
	in all cases _before_ adding to the workspaces, so that windows
	initially on all workspaces are added correctly to the MRU lists.
	Fix for #120907.

	* src/workspace.c (meta_workspace_add_window): handle sticky
	windows so that we add to add mru lists if needed
	(meta_workspace_remove_window): handle sticky windows so that they
	are removed from all mru lists if needed.
