Describe What Is Incomplete
I noticed that you've used the coveralls line-level ignore in a few places, but it's being terminated with # coveralls-ignore-end instead of # coveralls-ignore-stop.
We noticed ourselves doing this exact same thing accidentally, and as a result, coveralls was ignoring the rest of the file completely rather than turning off the ignore at the desired point.
parroty/excoveralls#197

I intended to search our codebase to make sure we got them all. I searched all of github instead, and happened upon the two examples in xgit. Thought I'd let you know. :)

Definition of Done
All uses of # coveralls-ignore-start have an associated # coveralls-ignore-stop.
