Looks fine *to me*.
Should be "easy" to do for BDB (for some values of "easy" ;-); in FSFS you
might have to rewrite the revs/ file, but with a hole where deleted contents
have been, so that the file positions stay the same.

(AFAIK addressing of content across revisions is done via byte positions,
isn't it?)

Thank you very much; I'm happy to see that there's progress!

Regards,

Phil
