We're trying to conform to PEP8 Python style standards. One of the guidelines is that lines should break at 79 characters, meaning this call would look like:

```python
Conference.auto_assign(list(Country.objects.filter(special=True)),
                       school.get_committee_preferences(),
                       school,
                       size)
```

I.e. each argument is aligned with the first argument of the call.
