What git ID though? Not all patches are fixing regressions or bugs
introduced by other patches, and even if they are, figuring out the ID
of the commit that introduced the bug by scraping Bugzilla comments is
not practical. If the existing svn commit log mentions a PR number
then that's easy to use, there's no need to complicate it.
