Thanks, Jared.

Yes, we considered having the Previous link not appear at all if there are
no previous pages, and I kind of actually prefer that most of the time. But
it's an interface design decision. Some of the designers feel like it's
beneficial to keep the control bar consistent, disabling the controls when
they don't apply, instead of having them take turns disappearing and
appearing under certain circumstances.
