Maybe just uur_previous or uur_prevundo or something like that. We've
already got a uur_prevurp, but that's really pretty misnamed and IMHO
it doesn't belong in this structure anyway. (uur_next is also a bad
name and also doesn't belong in this structure.)
I don't think we want to use 'ver' because that supposes that undo is
being used to track tuple versions, which is a likely use but perhaps
not the only one.
