mconf/nconf: mark empty menus/menuconfigs different from non-empty ones
Submenus are sometimes empty and it would be nice if there is
something that notifies us that we should not expect any content
_before_ we enter a submenu.
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" <yann.morin.1998@free.fr>.
