I still feel uncomfortable here because this means that the interface
to this very widely used program has changed in a backwards
incompaticle way (assuming the .proverc option is used).  As humans, we
can respond more robustly than, say, another software package, but this
means that we always have to remember the "extra step" we have to take
to avoid strange results.

The best way, in my humble opinion, to approach any API decision is
usually to come up with the absolutely best API possible and then
figure out to make that work.  I don't think adding the '--only' switch
is the best approach, so I expect that people will just not use the
.proverc.  If they *do* use .proverc, they'll forget they're using it
and we'll have a silent "action at a distance" confusing people -- it
certainly confused the heck out of me! :)

Of course, this is just what I and my colleagues are experiencing.  We
could be outliers here.

Cheers,
Ovid
