Thanks for flake8! My code is now less flakey.
I'm seeing W503 on a particular file, which from RTFM'ing, I know is
When I run pycodestyle on that file, I don't see W503.
That means flake8 is invoking pycodestyle with some command-line options.
I looked in the source for flake8 and couldn't find where this was.
I looked at the options for flake8 and didn't see anything that looked
like it would report how pycodestyle was being invoked.
How is pycodestyle being invoked?
Thanks for the help.
