Rob, thanks a lot for your script. I think there is a small glitch,
though:

This effectively returns the current working directory, taking care to
replace the $HOME prefix with a single `~`.

When I did this, the title bar showed the full path, without replacing
$HOME with a '~' character. I got rid of the "eval", and things were
fine.
