2004-08-27  Elijah Newren  <newren@math.utah.edu>

	Prevent an assertion failure that can occur after increasing the
	number of workspaces; also fix a warning and stacking order when a
	window is denied focus (fixes #150615)

	* src/window.c (meta_window_stack_just_below): the position of the
	window should be set equal to that of the one we want to be below,
	not 1 lower than that number

	* src/workspace.c (maybe_add_to_list): new function to add
	on_all_workspace windows to an mru_list, (meta_workspace_new):
	call maybe_add_to_list for all windows on the screen in order to
	initialize the mru_list
