In that case it 
might be preferable that the reuse of already deltified data is made of 
backward delta which is the reason you might consider feeding object in

Hmm. As I'm deltafying along branches, the delta data should actually be
fairly good; the only 'bad' result will be the sub-optimal object
ordering in the pack files. I'll experiment with some larger trees to
see how much additional savings the various repack options yield.

The fact that git repacking sorts by filesize after it sorts by filename 
should make this a non-issue: we always try to delta against the larger 
version (where "larger" is not only almost invariable also "newer", but 
the delta is simpler, since deleting data doesn't take up any space in the 
delta, while adding data needs to ay what the data added was, of course).
