This comment seems kind of opaque.

Why does it need the "WHERE delta like 'H4sI%'" and
"WHERE length(keydata)>160" conditions on all the UPDATEs?
(In particular the length ones. Even if monotone doesn't normally
generate keys that big, does it require that they're not? Could someone
have modified it to generate longer keys (so the not-base64 version
would still be longer than 160), and would that be interoperable?)

tests/t_migrate_schema.at hasn't been updated.
