Recap:
It looks like GNU detects that the hardlinks are the same and simply no-ops (I did an
straceand all it's doing isstat-ing each file and exiting). There's similar logic inuutils, but it's currently conditioned on the backup option. I think this is unnecessary since if source and dest are hardlinks to the same file, then no actual copy should be necessary. Let me know if I may be missing something though; there are an awful lot of obscure edge cases though (luckily there are many unit tests for them).
