This complex but extremely clear comment belongs not in the log
message, but near the new revmap_t data structure, IMHO.

A general thought about this change: I wonder if the code could be
simplified by doing away with the conditional, and simply always being
in "renumber revs mode", just sometimes we'd remap a rev to the same


Hmmm, now that I really think about that, I'm not so sure it's a good
idea. Maybe I should erase it. Or maybe I'll post it, just to see
what you say.

I looked hard for real problems in the changes, and didn't see any.
Should that worry us? :-)
