Subject: [PATCH 1/2] for-each-ref: "creator" and "creatordate" fields
This adds "creator" (which is parallel to "tagger" or "committer")
and "creatordate" (corresponds to "taggerdate" and
"committerdate").
The first line should not be in the message. I agree that it is
sensible not to call this "epoch", and "creator" is fine by me.
Thanks. Will apply.
