top: turn off the 'Ctrl' bottom window after some keys <=== port of newlib d66c1f39

Browse Source 
______________________________ original newlib message

To complete the implementation of this new feature, we
must address the problem created by any commands which
offer their own full replacement displays. Should that
'Ctrl' bottom window be active, a return from any such
command leaves that lower portion of a terminal blank.

While we could issue a 'TAGGED_TOSS' macro right after
invoking any of those 4 (currently) affected commands,
it is wrong to make them aware of this 'tagged' stuff.

So, I'll opt for a more generalized solution whereby a
notice regarding a corrupted screen is broadcast. Then
the logic already aware of 'tagging' can deal with it.
