The latest flake8 checks strings for escape chars, and also has a new
and better rule about line breaks before binary operators - which is
what knuth says should happen.
The escape char check was catching some asterisks in docstrings that
weren't actually providing much, since we already list type as "kwargs".
Just remove them.
Install latest flake8 so we can gate on this.
