Fix a few minor annoyances that snuck in

We had the normal infra pep8 ignores marked, but follow some of them by hand
in this codebase anyway. While E12* are not valid pep8, the prevailing style
of shade is in agreement with them. While we weren't enforcing them, a few
instances snuck in. Fix them and just turn the flags on.
