Thanks, installed (with a tiny change: I prefer an explicit 'stringp'

This contribution was small enough for us to be able to receive it
without a copyright assignment, but if you'd like to be able to
contribute in the future without restrictions, I suggest to start your
copyright assignment paperwork rolling. If you'd like that, I will
send you the form to fill and the instructions to go with it.
