So a variable, something like this?:

   break-hardlinks-on-edit

   "*When saving a file that exists under several names (i.e., has
    multiple hardlinks), break the hardlink associated with
    `buffer-file-name' and write to a new file, so that the other
    instances of the file are not affected by the edits.

    If `buffer-file-name' refers to a symlink, do not break the
    symlink."

I'm happy to write this, just want to make sure I'm headed down the
right design path.
