Those aren't bzr revisions, they're marks from a git stream dump.  If they're
messed up, then the parent links in the live git repo are messed up too.

I ran some auditing code on the first 1100 or so commits.  This is what
came out:

wrong parent links under :417
wrong parent links under :503
wrong parent links under :512
wrong parent links under :520
wrong parent links under :528
wrong parent links under :613
wrong parent links under :620
wrong parent links under :624
wrong parent links under :626
wrong parent links under :629
wrong parent links under :637
wrong parent links under :641
wrong parent links under :646
wrong parent links under :651
wrong parent links under :655
wrong parent links under :862
wrong parent links under :894
wrong parent links under :926
wrong parent links under :934
wrong parent links under :939
wrong parent links under :947
wrong parent links under :966
wrong parent links under :975
wrong parent links under :1011
multiple root commits: set(['commit@:676', 'commit@:1017', 'commit@:75', 
'commit@:579', 'commit@:39', 'commit@:2'])

Bottom line is, the topology is badly screwed up.  I already knew about the
multiple root commits; I'm fairly sure they relate to these junk branches

    21  commit  refs/tags/lost+found/d4cd8d7c34cc79dc4abd0fec33cec74afa33e2d0
  1723  commit  refs/tags/lost+found/12d398afa4d2b77d606b28fe43a2e5200c863419
  3595  commit  refs/tags/lost+found/e387e14faeea08877c99ddf798d5a4c9f7999c72
  3763  commit  refs/tags/lost+found/9a1501510c2a842e8597d695fec05563161a84b7
  3773  commit  refs/tags/lost+found/5cf718038f760d6dc2e21dee3ce98061a975488a

which I was going to delete anyway.  They seem to consist entirely of dummy
test commits by Glen Morris.
