devel/py-flake8-3: import py27-flake8-3.9.2nb3

Flake8 is a wrapper around these tools:

* PyFlakes
* pep8
* Ned Batchelder's McCabe script

Flake8 runs all the tools by launching the single flake8 script.
It displays the warnings in a per-file, merged output.

This package contains the last version supporting Python 2.x.
