/aiohttp/pytest_plugin.py produced different code on second pass

Howdy! Sorry you're having trouble. To expedite your experience,
provide some basics for me:

Operating system: Ubuntu Subsystem on Win10
Python version: 3.7.5
Black version: 19.3b0
Does also happen on master: no

To answer the last question, you have two options:

1. Use the online formatter at https://black.now.sh/?version=master, which will use the latest master branch.
2. Or run black on your machine:
   • create a new virtualenv (make sure it's the same Python version);
   • clone this repository;
   • run pip install -e .;
   • make sure it's sane by running python setup.py test; and
   • run black like you did last time.

Maybe this is the same as #1061?

Going to assume this got fixed with #1061.
