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

   6 https://github.com/python/cpython/commit/c4ef4896eac86a6759901c8546e26de4695a1389
   7 is not yet part of any release of Python but has been backported to all
   8 versions in Git (includeing 2.7!). It causes the tokenize.py module to
   9 emit a synthetic NEWLINE token for files that do not in fact end with a
  10 newline, which confuses pycodestyle's checks for blank lines at the end
  11 of a file. Fortunately the synthetic NEWLINE tokens are easy to detect
  12 (the token text is "").
