Emacs link breaking?

[Michael Still]

Hey,

I have a large source tree. I would like to be able to have a second copy
of that source tree where the second copy is composed of hard links. When
I edit one of these links, I would like emacs 21 to break the link and
create a new file (possibly by just renaming the link file to the backup
name).

I have seen this done, but I can't seem to find the config option in the
emacs config tool. Google implies it is the default, which doesn't match
my testing of what RedHat shipped me...

Any hints?

Thanks,
Mikal
