Which is correct according the surrounding syntax.

Longest single-sexp match would be r#"?\" since the correct
interpretation "r#"?\" are actually _two_ sexps.  So the "correct"
single sexp match in _this_ example would indeed be the shortest match
?\" here.  Obviously, depending on what transpires before, it is equally
easy to have the longer match be correct.
