I didn't change the deprecated plugin prototypes. I added a TRUE value
to the call of do_diff in the new (private) vtable. That being said,
the log message was misleading, which I fixed.

Good idea. See r12801:-) The point of that was actually to be able to
change the vtable without having to provide compat wrappers in all
three RA implementations (and to make the use of this API cleaner).
