This wrapping seems very aggressive. It begins wrapping with the very first param. I'd expect the wrapping to begin after a certain length, like at length 80 in text editors. I was also thinking this would be an HTML only solution like wrapping if something is outside the viewport, though admittedly I'm not sure if that's possible.

For instance, when you format something really long in clang-format, it wraps like this:

```
double func(double foo,
                       double bar, double fizz, double buzz)
```

It is a design preference though.
