Merge branch 'jv/pack-objects-narrower-ref-iteration'

Browse source 
The "pack-objects" command needs to iterate over all the tags when
automatic tag following is enabled, but it actually iterated over
all refs and then discarded everything outside "refs/tags/"
hierarchy, which was quite wasteful.

* jv/pack-objects-narrower-ref-iteration:
  builtin/pack-objects.c: avoid iterating all refs
