Merge branch 'ds/push-squelch-ambig-warning'

"git push" used to check ambiguities between object-names and
refnames while processing the list of refs' old and new values,
which was unnecessary (as it knew that it is feeding raw object
names).  This has been optimized out.

* ds/push-squelch-ambig-warning:
  pack-objects: ignore ambiguous object warnings
