The problem with reconsidering this assumption is that it leaves you with
no recourse but to move to a new line (and who knows, it may be a line
containing newly-wrapped text) and just do a fresh redraw when you get a
SIGWINCH.  That's going to leave even more text on the screen than now, for
gains only in pathological cases.
