Hmmm… neither do I. The only thing that condition could guard against is
`r->depth < -1`, which is nonsensical. You're definitely right about the
uninitialised `dp` being passed to readdir too.

Looks like I accidentally sent the wrong version of the patch (the version
crafted late night/early morning), especially judging by the broken English
in my commit message. I'll send the updated patch in a wee bit.
