Hi,

The patch below fixes the issue of vt(1) leaving behind some
environment variables defined (e.g. $TERM, $COLS, $LINES) after
it exits.

Incidentally, is there a better way to check if a program is
running inside vt(1) besides checking if $TERM is defined?

Seems good, committed.

Not that I'm aware of. I think $TERM is the best option,
and it's fairly portable to unix.
