bug#12001: 24.1.50; vc-diff always talks to CVS repository

[Richard Stallman <rms@gnu.org>]

It used to be the case that I could edit a CVS-managed file and type 
C-x v =, and it would generally not talk to the repository.
It would compare my workfile with what it had checked out,
exactly what was useful.

In the trunk built on July 2, C-x v = always tries to talk with the
repository.  This makes it useless when I have no network connection.

It was more useful the old way.
