Yep, for the record, those are fine (actually, I guess one of them got
axed in v3).

Even after reading your v3 reasoning, I still think it would probably be
OK for git-reflog to treat the "never" case as a noop. But frankly it's
not worth even spending any more brain cycles on. I can't imagine why
somebody would bother to run "reflog expire" without any expiration,
outside of git-gc.
The improved commit messages all made sense to me (including the NULL
oid bits in the final one), with the exception of one nit I pointed out
in one of the v3 messages.
