Oops, sorry I focused on testing big repos and forgot the test suite.
But hehe.. it's a good thing. That test was added by 735efde, where
fsck could keep on going after failing to inflate some blobs (instead
of hitting malloc failure and abort). Now it's even better, fsck
passes. I'll fix that up and resend with your squashes in.
