pack-objects: do not stop at object that is "too small"

Browse source 
Because we sort the delta window by name-hash and then size,
hitting an object that is too small to consider as a delta base
for the current object does not mean we do not have better
candidate in the window beyond it.

Noticed by Shawn Pearce, analyzed by Nico, Linus and me.
