I don't understand why anyone would want to *calculate* a target revision. Most people want to know exactly what revisons are involved in the operations they carry out. They don't just want "the last 20" (or "the first 37" or whatever).

It seems most unlikely to me that a user might not know what revision number is needed, but *did* know how far away it was numerically from (say) HEAD.

So let me rephrase the question: What exact problem does your suggestion solve?

I'm not against your idea, I just haven't seen the point of it yet...
