Pylint is a static analyzer of Python code. It seems appropriate
to use a static analyzer to analyze a static analyzer :-).
None of the changes here fix a flaw in flawfinder.
The goal here is to follow PEP 008 more closely in the hope that
the changes make it easier for other developers to improve it further.
