Thanks for fixing newlines. 

I could not really run this PR on Darwin bot  (we're missing this functionality). But I did a buddy test, i.e. synced the PR to my macOS machine and tested it with check-asan. 

This test succeeded - I also verified that changing order of matching doesn't break it, as on my machine 'Good so far.' log comes on top, where on the bot it's the opposite.

So I'm going to call it good. Thanks for contributing.
