Comment 7 for bug 225151

Since we now have orig.tar.bz2 in the archive originating as syncs from Debian, this is now rather critical to have supported for lucid:
there are 8 source packages in Debian that should be synced to newer versions according to our sync policy, but can't be because sync-source.py will not allow them because they reference a previously-seen .orig.tar.bz2.
