Provide 80x24 fallback for ansi and vt100 (#465)
Not all terminals will necessarily respond to the TIOCGWINSZ ioctl,
particularly much older ones providing vt100 or ansi terminals, which
will have a fixed 80x24 size. If they respond with some kind of
non-sensical value here, then at least give the ansi and vt100 terminals
their default so they can draw.
