As a more useful (I hope) reply, my opinion in this case is to just make the line a little longer. Even if you can't read it all at once, it is pretty obvious what comes next: The rest of the error message. There is no additional functionality hidden there, and you don't need to see it all at once to grasp the meaning of the code.
