Interesting. I hadn't previously thought about the form of those punctuation marks. Upon looking at them, a dot intuitively ends a sentence. A dot with a line intuitively ends a sentence with emphasis, and a dot with a meandering line questions. From that perspective a question mark really does indicate uncertainty and possibly a question.
