I'd write
SwitchWindow(display && D_other && (D_other != fore) ? D_other->w_number :
NextWindow());
I see nothing here that asserts D_other being nonzero otherwise.
As suggested by Jeroen, I am afraid it could crash a fresh screen
session that only has one window.

Yes. I'd be very interested to learn the circumstances when the other
command would respond with "This IS window (n)" -- Never seen that happen.

Please be save.
I don't think Jeroen meant to remove that assertion.
