top: avoid premature forced loss of that bottom window <=== port of newlib f40fc402

______________________________ original newlib message
----------------------------------- ( minus git hash )

In the commit shown below the bottom window was forced
off if a full screen replacement function was invoked.
It did so by setting Frames_signal after calling those
routines from the keys_global function. However, there
was sometimes a possibility such action was premature.

At least two of those full screen replacement routines
may issue an error message & return without corrupting
the screen. As such, forcing off that bottom window is
totally unnecessary. It therefore should be preserved.

So this commit just moves the setting of Frames_signal
to the full screen replacement routines when possible.
