Hi.
I was recently bitten again by Emacs destroying hard-links when saving.
I have to admit, I consider this default behaviour pretty rude.
What is the rationale for such a default? And, can we perhaps find a
way to change this such that saving a hard-linked file doesn't undo the
link?

In other circumstances, the other behavior is pretty rude as well.

While I consider the default Emacs behaviour to be appropriate, it is
possible to detect that a file has hardlinks and warn if you're saving to
such a file.
It may be useful to provide such functionality?

Warning might be a good feature and even a good default, indeed, since both
options can be quite rude: sometimes the links are really there because
you really want to keep those N places equal, and other times the links
should only be there as long as the N files are equal.

Careful with these warnings: they could potentially be a terrible nuisance, since saving your edits is a very frequent operation.
If we are going to introduce such a warning, it should be issued only once per session for a given buffer.
