Subject: opendir(/dev/fd/n) should fail

I discovered a strange behaviour when accessing /dev/fd:

         ls -l /dev/fd/0
         ls -l /dev/fd/0/1
         ls -l /dev/fd/0/1/2/3/4/5
         ls -l /dev/fd/0/1/2/3/
         ls -l /dev/fd/0/1/2
         ls -l /dev/fd/0/1/2/3
         ls -l /dev/fd/0/1/1/1/1

gives:

lrwxrwxrwx 1 hk Benutzer 0 Jan 21 23:52 /dev/fd/0 -> /dev/pty0
lrwxrwxrwx 1 hk Benutzer 0 Jan 21 23:52 /dev/fd/0/1 -> /dev/pty0
ls: cannot access /dev/fd/0/1/2/3/4/5: Not a directory
ls: cannot access /dev/fd/0/1/2/3/: Not a directory
lrwxrwxrwx 1 hk Benutzer 0 Jan 21 23:52 /dev/fd/0/1/2 -> /dev/pty0
ls: cannot access /dev/fd/0/1/2/3: Not a directory
lrwxrwxrwx 1 hk Benutzer 0 Jan 21 23:52 /dev/fd/0/1/1/1/1 -> /dev/pty0

I'd expect ls /dev/fd/n/p to fail for any combination of n and p.

I'm using 1.7.32. Has this been fixed meanwhile?
