isparta coverage HTML places branch at wrong location

[graingert]

Using this repo https://github.com/graingert/isparta-coverage-error

(npm install && npm test) I get the branch error placed in the wrong location. (It should be on line 8)

I originally raised this on a isparta loader ColCh/isparta-instrumenter-loader#7

@graingert the author has abandoned this project, I'm going to be forking it so I can start applying some fixes myself. (I've asked him for write access to the repo and publish access on npm, but haven't heard back yet)
