The star indicates that this is a function that returns a generator, i.e.
implicitly returns an iterator in which you shove values with `yield`. I think
you wouldn't want to wrap between `function` and `*`. We currently don't, but
more by chance - it's a side effect of not breaking before a binary operator.
`function*` cannot be one token, there may be whitespace and comments in
between. We could have a `generator star` token, but there are places where
that'd be hard for us to detect, e.g. the class method above. Having a
`generator star` only occasionally be recognized of course would be rather
confusing.
So I'd punt on this for the time beimg. I've added a test to make sure we
correctly wrap above. Does that make sense?
