Don't bother.  Just always default to up-to-date.

Make it `state' and not a list.

Redundant comment.

The test is wrong (it prevents non-interactive use where you specify
the state explicitly).
The above should simply be (unless state (setq state 'up-to-date)).

> +(defun vc-dir-hide-up-to-date ()

Why bother?
