Lines in a case statement are treated as irrelevant

[campezzi]

This may not be ExCoveralls-specific, but it seems lines inside a case statement are not counted as relevant. This means coverage reports may return 100% coverage even when one of the branches of that case are not exercised.

I put up a sample repository demonstrating the issue (with instructions on the README file): https://github.com/campezzi/coverage_fail_demo

Thanks for the report. I could confirmed the same behavior (with both excoveralls and cover).
The line (just the value reference) seems not taken as relevant, and it might need some treatment at elixir/cover side.
