Hmm... I considered this, but I wasn't sure if there were any edge
cases where the first path returned by tree_next might not be the
path passed to tree_open; so I decided to take the route which I
knew would always work.

If you're sure that a first-time-through-the-loop flag will work,
feel free to change this. :-)
