[PATCH] Disable VC when Emacs is noninteractive -batch

[Michael Olson]

I've noticed lately that VC can behave badly when trying to build one of
my Emacs Lisp add-on programs.  If a file has been deleted at some
point, it will interrupt the build to prompt me about whether to restore
it -- this is a show-stopper.  Also, even when building Emacs (as of a
week ago, at least), VC prints several spurious messages on the console;
they are harmless in this case, but nonetheless provide needless
clutter.

I think that VC should be disabled by default when emacs is passed the
-batch option.  The attached patch implements this.  Is it OK if I
install it?  VC is supposed to be for working interactively with version
control systems, so I can't see any reason not to install the patch.
