Restarting a svn->git conversion from scratch will usually generate
the same commit hashes. However, there's an unfortunate point where
the svn mirroring messed up [1] that resulted in bogus metadata on the
manufactured git commit, and all hashes from that point on are broken.
(Ironically this was from a bug in the svn mirroring process, not the
svn->git conversion or git itself.)

Assuming we're confident the issue in the svn mirroring process is
fixed and will not recur we can redo the conversion, with a one-time
change to all hashes from the offending commit on, and they would not
change again in the future.
