Hmm, you're right. I didn't take into account the corner case where a
triple-quoted string contains single-quoted strings. Thanks for
catching that. (Fortunately, it's a rare occurrence that has certainly
never happened in the field -- you'd have to do a triple-quoted string,
then a single quoted one, _then_ an unbalanced close parenthesis.)

I figured, but I thought I'd mention the quick-and-dirty way out first.
