  20. > One might be tempted to use initial failure from dirname() to determine if a
  21. given directory is empty; however, this doesn't work in general, as on some
  22. systems it might not be possible to differentiate between a non-existant
  23. directory and an empty directory.
  24.  
  25. And how about directories which contain entries which you're not allowed to see?

  30. Oh, jeez... I don't see ANY value in returning "." at least, whether it's 
  31. "there" (for OS purposes) or not.  What's the point, after all???

  33. > ...and not require any special casing (and it is trivial to filter this out at 
  34. a higher level).
  35.  
  36. Trivial doesn't mean anything different, here, than "recurring and familiar 
  37. nuisance".
