Should function signature formatting be applied to this?

[ixje]

Let's assume the following function exceeds the maximum line-length

func foo(name1 string, name2 string, name3 bool, name4 []byte) (*[]byte, error) {
	return nil, nil
}

golines will then reformat it to

func boo(
	name1 string,
	name2 string,
	name3 bool,
	name4 []byte,
) (*[]byte, error) {
	return nil, nil
}

This suggests to me there should be at most 2 function signature styles

1. single line (if within max line length)
2. multi-line with each param on a separate line (if exceeding max line length)

However, if we take something like this

func foo(
    name1 string, name2 string, name3 bool, name4 []byte
) (*[]byte, error) {
	return nil, nil
}

or this

func foo(name1 string, name2 string, name3 bool, 
    name4 []byte) (*[]byte, error) {
	return nil, nil
}

golines will not format the function signature. Is this expected behaviour or should it actually format it using the multi-line params approach?

Good question!
