-Subject: [PATCH] Keep compability with stdlib tokenize.py changes

-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
