  SVN rev 207464 on 2010-05-01 14:29:33Z by jilles
  
  MFC r206773: ln: Do not delete a file by hardlinking it to itself.
  
  Two pathnames refer to the same directory entry iff the directories match
  and the final components' names match.
  
  Example: (assuming file1 is an existing file)
    ln -f file1 file1
  This now fails while leaving file1 intact. It used to delete file1 and then
  complain it cannot be linked because it is gone.
  
  With -i, this error is detected before the question is asked.
