This seems to have been stalled but I think it would be a better
approach to use a custom callback for error reporting, suggested by
Ævar, which would be where his fsck API clean-up topic would lead
to.

If it is not ultra-urgent, perhaps you can retract the ones that are
queued right now, work with Ævar to finish the error-callback work
and rebuild this topic on top of it?  Thanks.

OK - that works. My original idea was to rewrite it using an
error-callback but using starts_with() instead of the ID that Ævar's
work will provide, but seeing that at least one other contributor (Peff)
seems OK with the patches, rebasing mine on top of his works too. I'll
also take a look at his patches.
