Dirk, All,

I think we still want submenus to be visible if they are not hidden by
any condition in the Kconfig. If the developper did not explicitly add
masking condition, we should *not* try to mask it from the frontends.

However, I agree that entering an empty menu can just be deceptive. If
we could find a way to render an empty menu, and prevent the user from
entering it, then that would be a huge win, I think.

For example, menus are rendered as thus for now:

    This is a submenu  --->

What about representing empty submenus as thus:

    This is a submenu  ----

Also, we have menuconfig which are simply empty if not selected, but can
anyway be entererd like any other submenu:

    [ ] menuconfig entry  --->
        (Always empty when entered if not selected)

which could be similarly rendered as:

    [ ] menuconfig entry  ----

This one is really deceptive, and should be handled in the same scheme
as well.

Any better scheme highly suggested! :-)
