In the presence of many tags, the use of oid_array_lookup() can become extremely slow. We should rely upon the SEEN bit instead.

This affects the tag-peeling walk as well as the switch statement for adding the peeled object to the correct oid_array.

@dscho: just so you know, when you @-mention someone in a commit message (or PR description leading to the merge message) it will notify that user whenever a commit with that message is pushed. (I've gotten quite a few today...) Using back-ticks in the message will stop that. (I'm guilty of this, too.)

FWIW I've added amend! commits that edit out the GitHub handle by replacing it with the real name.
