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>. Signed-off-by: Dirk Gouders <dirk@gouders.net> Tested-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Reviewed-by: "Yann E.
