@smashwilson: This change is failing on Circle CI. Should Circle CI be passing? (I ask because I'm not sure if atom/watcher migrated from Circle CI 1.0 to 2.0 before 1.0 went EOL.)

I rebuilt master, and Circle CI fails on master too: https://circleci.com/gh/atom/watcher/566

@jasonrudolph Looks like clang-tidy has gotten smarter in the time since I was last spending time on this repo. I've fixed the new problems it found in #175, so this should be able to pass now 🤞
