Hi!

Yes, I just did it in 24e262f, along with a test case and documentation.

Thanks a lot for taking the time to work on this, I appreciate.

Hmm, could be a bug, but I don’t seem to have them here.

Yes, with ‘cond’ or ‘match’.

I think we now have something that works well.  Commit 9241172 slightly
changes ‘roll-back’ to support roll-back when a past generation is
missing (which could happen when the user deletes it.)

So now I think I’m almost ready to tag 0.1 later tonight!

Thanks!
