Nick, your "totally untested" code works perfectly!

I'd actually thought of using expout, but was hoping for a more compact
solution. I think I've exhausted all the ways I've ever heard of
escaping/emasculating a bang in a command line. Was sort of hoping to find
some shell guru out there. The thing is, though, it's one of those
situations where the expansion functionality in autotest is just a little
less functional than the shell itself.

Thanks!
