100% coverage reported incorrectly

[jedireza]

I'm working with lab-babel in a larger project and suspected some incorrect coverage reported. To demonstrate I updated the jedireza/lab-es6 example.

You just need to clone it, npm install and then npm test.

It shouldn't be 100% covered because I never tested the subtractSomething function.

Same here. Seems like the auxiliaryCommentBefore and auxiliaryCommentAfter in https://github.com/nlf/lab-babel/blob/master/lib/index.js#L14-L15 are responsible for that. Removing these two lines brings back proper code coverage.
Actually I don't know why they were introduced in the first place so I hesitate to open a PR. Maybe @phated can clarify why they are/were needed.

All the context needed should be in #4

Lab doesn't (or at least didn't) have a way to "skip next line" the way that istanbul did, so each line of generated code needed to be wrapped in a before & after comment. If lab has updated to allow comment to "skip next line" that would be ideal to use; however, I've stopped using lab since they don't support older versions of node.
