[issue42895] Return multi-line list concatenation without parentheses returns only first operand

As Guido says, a full explanation will have to to a user-forum such as https://discuss.python.org/c/users/7 but consider this example and see if it gives you insight:

def demo():
    x = 1
    return (
        x - 1
        )
    print("This is not executed.")
    - (5 * x)

and remember that `+` can also be a unary operator.
