If you indeed are using bash-4.2.37, you can enable variable expansion
by running `shopt -s direxpand'.  This will produce the behavior you
want.

I'm wondering if you've got programmable completion enabled, or whether
you're running a different version of bash than bashbug indicates, because
stock 4.2.37 doesn't quote the dollar sign.
