I was just looking at PrettyPatch, and wondering whether we'll want to replace it at some point (with a Python script, or with some some third party module).

I think the main advantage of replacing it is to enable pretty patches to be generated when running run-webkit-tests even if ruby isn't installed ( bug 620270 ). Also, some parts of PrettyPatch.rb may be unnecessary now, e.g. there are references to SVN in that file.

Dirk, I remember at one point you mentioned that we could rework the way that diffs are made -- do you remember what you were thinking?
