Output is insensitive to terminal width

[Freaky]

The current output width is 106 columns, which by happy coincidence is precisely the width of my usual terminals.

This coincidence seems unlikely to be universal, and some sensitivity to this would seem to be in order.

should be fixed in #22

Fixing overwrite mode fixes height, not width ;)
