Whatever we decide to do in the future, author rewriting seems like
extremely low value compared to having matching SHA1s.  I think we should
get a clone on github.com that matches the existing git.webkit.org SHA1s
and then make sure that they stay in sync (either with rewriting or not,
but whatever webkit.org does).
