This causes problems for other projects incorporating dib; we don't have a specific need for a cap. Fix a few issues, mostly spacing or regex matches. No functional changes. W503 and W504 relate to leaving artithmetic operators at the start or end of lines, and are mutually exclusive and, due to "ignore" overriding the defaults both get enabled. It seems everyone gets this wrong (https://gitlab.com/pycqa/flake8/issues/466). Don't take a position on this and ignore both. Use double # around comments including YAML snippets using "# type: " which now gets detected as PEP484/mypy type hints. Change-Id: I8b7ce6dee02dcce31c82427a2441c931d136ef57
