Sorry for the lack of clarity.  I mean allowing

	[rebase]
		backend = am
		backend = apply
		backend = futuristic

with behavior

- on "git" that understands am but not apply or futuristic, use the am
  backend
- on "git" that understands apply but not am or futuristic, use the
  apply backend
- on "git" that understands apply and futuristic, use the futuristic
  backend

That way, a single config file is usable on all three versions of Git.

Thanks,
Jonathan
