I'm sorry, that part isn't in the final version.
I had sent the patches as I made the implementation. This kinda made this
part (and a couple others) weird because a later patch gets rid of it.

I'll send the v2 revision as a single patch which will give a clear picture
of the changes. No fixed url is in it.

Just a little oops from a first time contributor :)
