Note inspiration for this script to give credit where it's due

There is some confusion in the Git log of this file.  Specifically,
the commit message on 7b7f1702 incorrectly indicates that there was
"potential fear" about copyright infringement.

Upon review of this situation, there is, in my opinion, no concern of
copyright infringement here.  This is not legal advice; it is my
opinion based of years of work on copyright policy for FOSS.

However, Elliott Mitchell's idea was obviously helpful as inspiration
in writing this script and deserves credit.  Ideas alone, however,
are not to my knowledge copyrightable anywhere in the world.
