undefined variables

[piotr-s-brainhub]

I have found some undefined variables:

• res:

  winston-loggly/lib/winston-loggly.js

  Line 160 in ff56088

  var result = res[res.length-1];

• func:

  winston-loggly/lib/winston-loggly.js

  Line 168 in ff56088

  return func();

Are they global variables? Or this code is never reached?
