Doesn't this patch essentially make the --unpacked option to rev-list and
the --incremental option to pack-objects the same thing?

The semantics of the --unpacked has been defined that way from the very
beginning, and I've always wondered how the option and --incremental
should interact with each other.  I think the approach your patch takes
makes sense.

Sign-off?

Ahhh.  Ugly but don't you mean "! (rev-list | grep)"?
