It doesn't state explicitly that you can use the telldir cookie()

undefined after a rewinddir() --- which is much less violent than a
closedir()/opendir(), I would definitely argue that an application
programmer would be very ill-advised to rely on this working.
(Of course, I'd argue that an application programmer shouldn't use
telldir/seekdir at all.....)
Ulrich, is it too late to insert a clarification that the telldir()
cookie isn't guaranteed to be valid after closedir() *or* rewinddir()?
More fundamentally, the telldir cookie should never be valid when
applied to a different DIR * (even one that refers to the same directory.)
