Another way of looking at it is that not overwriting when links > 1
means that the data I thought I securely deleted is still present
somewhere on my computer and I have no easy way to find it.

I believe that this change creates a security hole and should be
reverted.  It the user specified '-P', either the file should be
over-written or the file should be left untouched (not deleted).
This is the only way that the user can be protected both against
accidently over-writing a wanted file when an unwanted link is
removed and failing to over-write an unwanted file which had a
stray additional link.
