prevent indentation confusion

[pavelnikolov]

Unlike in #2 I'd like to actually prevent breaking long lines in the middle of function definition and causing indentation confession. Right now gofmt accepts both:

func somethingTooLong(ctx context.Context, longArgument string, anotherOne func(time.Duration) bool) (int, error) {
	// foo
}

and

func somethingTooLong(
	ctx context.Context,
	longArgument string,
	anotherOne func(time.Duration) bool
) (int, error) {
	// foo
}

I personally never want to break long lines in Go, however many other people do. That is why I'd like at least to enforce no indentation confusion by splitting the declaration of a function in the middle of it's args, for example:

func somethingTooLong(ctx context.Context, longArgument string,
	anotherOne func(time.Duration) bool) (int, error) {
	// foo
}

This ^ is a big no-no, IMHO. How do I enforce no splitting of argument list in the middle?
