A new function menu_is_empty() was introduced and empty menus and menuconfigs are now marked by "----" as opposed to non-empty ones that are marked by "--->". This scheme was suggested by "Yann E. MORIN" . Signed-off-by: Dirk Gouders Tested-by: "Yann E. MORIN" Reviewed-by: "Yann E. MORIN" Signed-off-by: "Yann E.
