Re: Annoyance wrt ref@{1} and reflog expiry

Or we could change the lookup side to use the value of the ref
itself when asked for @{0}, and use the "old" side of the only entry
when asked for @{1}.  That way, we do not need to play games with an
artificial entry at all, which may be a better solution.

In other words, looking up @{0} will be the only special case.  A
natural consequence of the above way to look up @{1} is to look at
the old side of (N-1)th entry in the reflog for @{N}.

I am starting to like this idea, but I am not sure how tricky the
actual implementation would be.
