top: allow sticky 'Ctrl' bottom window code by #define <=== port of newlib 16e202d2

______________________________ original newlib message

After making that new bottom window more persistent, I
decided to offer a build choice for somebody who might
prefer to have the rug pulled out from under him while
reviewing window contents should some target task end.

If 'TAGGED_BRIEF' is defined old behavior is restored.

[ it should be noted, however, that when this define ]
[ is active we'll lose any benefit of onetime update ]
[ for the bottom window. just like with the original ]
[ behavior, it is repainted with every update cycle. ]
