Unwrap function arguments

Not sure if this is the right place to ask.

What rules do I add to convert a function written like this:

```
 func replaceOverlay(
        ofStyle style: MyStyle,
        with overlay: MyOverlay?
    ) {
...
}
```

to:

 ```
func replaceOverlay(ofStyle style: MyStyle, with overlay: MyOverlay?) {
...
}
```
