merge-queue needs to push commits to the WebKit repo. This process involves canonicalizing those commits (adding identifiers), running `git svn dcommit`, updating the associated pull-request with whatever we just landed then finally closing the relevant bug and pull request. The "updating the associated pull-request" is the most difficult step, because we need to re-canonicalize the landed commit since `git svn` will have added a subversion revision into our commit, which will change the commit hash.
