I see, so it's not a 'hard' syntactic issue, the limitation is in the
rules for look ahead, namely that if the parser feels it has a complete
sentence then it never looks at the next line. OK, that's a crisp
answer. Given how complex all that stuff is, I'd not even dare ask for
that to be touched, something would break for sure. (Me, I've always
preferred breaking lines before && and ||, but it's hardly important.)
