'ntpq -c ":config"' does not work (it probably never did)

Or there's the simplest possible fix, which I just pushed.  The expression used
to process the argument of -c just changed from

                        interpreter.onecmd(command)

to

                        interpreter.onecmd(interpreter.precmd(command))

Thanks for catching this.  If anything goes sproing, bug me.
