I forgot to mention that explicitly sending SIGWINCH (using "kill -WINCH")
doesn't trigger the problem.  Also, this doesn't seem to happen when
changing the width/height of the window by 1-2 lines/columns, only when
the window is resized by larger amounts (5-10 lines/columns).  Either
height or width resizing triggers this.
