Best practice for wrapping function arguments

Style guide should advise wrapping function arguments that go over maximum line length.

``` js
function someVeryLongFunctionName(someVeryLongArgumentName1, someVeryLongArgumentName2, someVeryLongArgumentName3) {
// Function body
}
```

or:

``` js
function myFunction(someArg1, someArg2, someArg3, someArg4, someArg5, someArg6, someArg7, someArg8) {
// Function body
}
```

Wrapped:

``` js
function myFunction(someArg1, someArg2, someArg3, someArg4,
someArg5, someArg6, someArg7, someArg8) {
// Function body
}
```

Review the JavaScript style guide's existing guidance on function declarations and line length. Add a recommendation and examples for wrapping long function argument lists, then confirm the guidance clearly covers the shown cases.
