Havoc Pennington 6557627d8f remove unused variable 
2002-11-20  Havoc Pennington  <hp@pobox.com>

	* src/window-props.c (set_icon_title): remove unused variable

	* src/screen.c (meta_screen_new): read an existing
	_NET_CURRENT_DESKTOP and restore it if set. Makes a restart even
	less visible.

	* src/workspace.c (set_active_space_hint): don't set the hint
	during the process of unmanaging a screen
