Subject: [PATCH] Use platform independent path separator

When normalizing paths in flake8.utils, we use the os.path.sep constant
to determine if the item is intended to be a path. If Windows users then
have a path like

    foo\bar

Specified, they will get the same behaviour as a *nix user with

    foo/bar
