Comment 1 for bug 1444170

Leo, how is flake8 invoked to check for errors/warnings? I’m asking because webbrowser-app has a unit test that runs flake8 on its autopilot tests, so any error/warning should prevent it from landing. See http://bazaar.launchpad.net/~phablet-team/webbrowser-app/trunk/view/head:/tests/unittests/sanity/CMakeLists.txt.
