Why?  hardlink isn't going to replace files that are different, so there
is no gain in not letting hardlink link all copies that are the same.

It is smart enough to look at the stat() info before reading the
contents for comparison, so files of different sizes aren't going to be
compared just because they have the same name.

The whole point of running hardlink is to reduce disk usage; why not let
it try to do the best job possible?
