2002-11-19 Havoc Pennington <hp@pobox.com> Should really fix #98303 * src/prefs.c (meta_prefs_change_workspace_name): add bad hack to treat empty string the same as null * src/menu.c (get_workspace_name_with_accel): allocate one more than the length of "name" so we have room for a nul byte (and don't malloc(0) on empty strings). Also some formatting cleanups.
