Some auto-genereated docstrings are super long and difficult to read

[rustyhowell]

Some of the docstrings are not being generated correctly, and are being stuffed on a single line. This makes it very difficult to read the documentation. It's probably the reason the readthedocs also doesn't look good.

If you take a look at feature_flags_api.py, line6 you can see what I'm talking about.
