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.
