Log Message:
py-codestyle: updated to 2.4.0

2.4.0 (2018-04-10)
New checks:
Add W504 warning for checking that a break doesn’t happen after a binary \ 
operator. This check is ignored by default.
Add W605 warning for invalid escape sequences in string literals.
Add W606 warning for ‘async’ and ‘await’ reserved keywords being \ 
introduced in Python 3.7.
Add E252 error for missing whitespace around equal sign in type annotated \ 
function arguments with defaults values.

Changes:
An internal bisect search has replaced a linear search in order to improve \ 
efficiency.
pycodestyle now uses PyPI trove classifiers in order to document supported \ 
python versions on PyPI.
‘setup.cfg’ ‘[wheel]’ section has been renamed to ‘[bdist_wheel]’, \ 
as the former is legacy.
pycodestyle now handles very long lines much more efficiently for python 3.2+.
You can now write ‘pycodestyle.StyleGuide(verbose=True)’ instead of \ 
‘pycodestyle.StyleGuide(verbose=True, paths=[‘-v’])’ in order to achieve \ 
verbosity.
The distribution of pycodestyle now includes the license text in order to comply \ 
with open source licenses which require this.
‘maximum_line_length’ now ignores shebang (‘#!’) lines.
Add configuration option for the allowed number of blank lines. It is \ 
implemented as a top level dictionary which can be easily overwritten.

Bugs:
Prevent a ‘DeprecationWarning’, and a ‘SyntaxError’ in future python, \ 
caused by an invalid escape sequence.
Correctly report E501 when the first line of a docstring is too long.
Support variable annotation when variable start by a keyword, such as class \ 
variable type annotations in python 3.6.
pycodestyle internals have been changed in order to allow ‘python3 -m \ 
cProfile’ to report correct metrics.
Fix a spelling mistake in the description of E722.
‘pycodestyle –diff’ now does not break if your ‘gitconfig’ enables \ 
‘mnemonicprefix’.
