Subject: [PATCH] Keep compability with stdlib tokenize.py changes
https://github.com/python/cpython/commit/c4ef4896eac86a6759901c8546e26de4695a1389
is not yet part of any release of Python but has been backported to all
versions in Git (includeing 2.7!). It causes the tokenize.py module to
emit a synthetic NEWLINE token for files that do not in fact end with a
newline, which confuses pycodestyle's checks for blank lines at the end
of a file. Fortunately the synthetic NEWLINE tokens are easy to detect
(the token text is "").
Fixes #786
