I think IN_ORDER really only applies to *binary* trees, not arbitrary

How true. Even if we were giving a sorted output (and dir-iterator
doesn't and there is no need for it to), dir/ should come before any
of its contents, so for that application we can use pre-order, and
there is no sensible and useful definition of in-order.
Thanks.
