Thomas Thurman fee1fb094a Allow any keybinding pref to be specified either with <foo>, a string, or 
2004-04-17  Thomas Thurman <thomas@thurman.org.uk>

        * keybindings.c (count_bindings, rebuild_binding_table):
        * prefs.c (change_notify, screen_bindings,
        window_bindings, init_bindings, update_binding,
        find_and_update_list_binding, update_list_binding,
        meta_prefs_get_window_binding): Allow any keybinding pref
        to be specified either with <foo>, a string, or <foo>_list,
        a list of strings, or both. Fixes #164831.
