I'm not really sure why these lines are showing up in the diff.  They are already set that way in master: https://github.com/bgrins/spectrum/blob/master/spectrum.js#L68.  I will try pulling it down and see if it doesn't cause any problems, but have you pulled in the latest version? I guess we could start from scratch by taking a diff of this and branching, then applying the diff to the new branch and setting up a new PR, but I'll take a look first.
