code: function WatchReporter(runner) {
    var self = this;
    Base.call(this, runner);
    runner.on('end', function() {
      if (this.stats.failures) {
        Base.prototype.epilogue.call(self);
      }
    });
  }
docs: Like the "min" reporter that comes with Mocha[0], but doesn't clear the
  screen.
