While cleaning up the public repo seems sensible, how does that affect
the size of a clone?  clone should be getting objects that are
referenced, and thus not depend on stray objects.   Or is it about
receiving compressed objects that are all compressed together into packs
and thus much better compressed?

I did gc on my own repo and it was 100 MB.  After --aggressive it was
indeed 13.   I don't really understand what's going on - where are those
87 MB being taken up, given that in theory the same number of objects
are reachable.
