"recover" is a bad word actually. What I mean is "bring it back to a
consistent state where I can use svnadmin dump and get something out of
it". If an entry is corrupted, trash it and move on to the next piece of
data. If it depended on the previous one that was trashed, loose it too,
and so on. If nothing is left after this, well, we tried.

If it's wrong, trash it and move on to the next piece. That's what fsck
does. You may end up with just 10% of the data, due to the internal
deltas, but hey, it may contain that crucial record you needed...

Agreed. I will check the bug database and request it if it's not there
yet.
