We actually already have a test that rejects trailing whitespace in Python, at
python/samba/tests/source.py:185, run by autobuild and `make tests TESTS=source`.

There is also a `make pep8` that runs the less interesting subset of flake8. 
Anyone who runs it sees over seven thousand lines of complaint and decides to
focus on something else.
