Wrong behaviour with W601 and W503

[mastak]

Step to reproduce:

1. Create code with W503:

   def update_actions():
   return (
       some_big_function_name_1()
       + some_big_function_name_2()
   )

   > some.py

2. pycodestyle ./some.py => empty output
3. Add pycodestyle settings

   [pycodestyle]
   ignore = W601

   > tox.ini

4. pycodestyle ./some.py => ./some.py:4:9: W503 line break before binary operator

With default settings, there is no warning, but if you add a rule to ignore W601 pycodestyle shows W503 errors.

W503 is ignored by default, as are some others. When you set ignore directly, the default ignores get overridden.
