Lambda parameters dont line wrap

[saik0]

val barParams = ParameterSpec.builder("f",
        LambdaTypeName.get(parameters = generateSequence { Unit::class.asTypeName() }.take(20).toList(),
                           returnType = Unit::class.asTypeName()))
        .build()

val file = FileSpec.builder("", "Foo")
        .addFunction(FunSpec.builder("bar")
                .addParameter(barParams)
                .build())
        .build()

file.writeTo(System.out)

outputs:

fun bar(f: (Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit, Unit) -> Unit) {
}

This should trigger one-per-line parameters:

fun bar(
    f: ...
) {
}

but I don't think we'll worry about wrapping the actual lambda signature.

Fair enough

[Egorand]

Currently parameter wrapping depends on the number of parameters and not on the length of the code, which is something we can improve. The difficult part is figuring out the length of the parameter code before it's emitted.

Fixed.
