Hi all,

I've discovered a discrepancy between the parents of a file's knit, and
the revision.

Take errors.py.  The following file versions have >2 parents according
to the kint:

robertc at robertcollins.net-20050914172314-4c220f175bb62fe0
robertc at robertcollins.net-20050927072440-1bf4d99c3e1db5b3
robertc at robertcollins.net-20050928052554-beb985505f77ea6a

But according to cat-revision, the actual revisions have only two parents.

For revision robertc at robertcollins.net-20050914172314-4c220f175bb62fe0

The revision parents are:
robertc at robertcollins.net-20050914151159-2986150cde2d744a
abentley at panoramicfeedback.com-20050914165444-335a16dc80f7c129

The errors.py parents are:
abentley at panoramicfeedback.com-20050914165444-335a16dc80f7c129
abentley at panoramicfeedback.com-20050914163546-ef044baf4ef9c135
robertc at robertcollins.net-20050914145408-6532b86aa3e8423a
robertc at robertcollins.net-20050914151159-2986150cde2d744a

I would have imagined it could be the other way around, due to ghosts.
But it's hard for me to see a benign explanation for this.
