   It's probably a good idea to also add :-
   (setq backup-by-copying-when-linked t)

Or, for more exact vi work-alike characteristics:
(setq backup-by-copying t)

However, note that the default behavior (setq backup-by-copying nil)
can be very important when working on large projects.  For example,
you can have multiple copies of the same directory tree, where only
editted files require distinct storage.
