No, this brings us full circle to the original state of affairs
where you quit tog and then there is leftover stuff on the bottom
line to the right of your shell prompt (if alternate screen switching
is disabled).

I tried to steal what vi(1) does, comment and all, see below, but
that doesn't work as expected.  As soon as I call refresh() before
endwin(), the screen is cleared.  I don't understand why this
happens.  Maybe it's related to tog's use of panels, which vi doesn't
have?
