What is the best way to generate an svn compatible diff when using git svn?

Question

I'm using git to track the wireshark project. I'd like to submit a patch, however the format required is the output of the following (see http://www.wireshark.org/develop.html):

svn diff > my-new-protocol.patch

Which is a different format what git-diff produces.

What are my options?

There is a helper script to do this: https://gist.github.com/44537
