Indeed. In theory you could pipe to tail instead (or to less and
immediately hit 'G'), but I can't think of a good reason that this would
have appeared above the header when I originally wrote the patch.

Anyway, it doesn't seem that the tests care about where this is (they're
just looking for for a line that begins with the object id and ends with
its offset), so I think this could probably be moved without thinking
too hard about it.
