Poll: Should Comments Support Lists?

Most semi-popular threads now contain comments where people try to make lists the usual markdown way, and it turns into one long tangled mess because HN requires a blank line before anything is rendered as a new line. Should the comment syntax support these lists? The vast majority seems to use - as item marker (although some also use asterisks, it already being used for italics would make things more complicated than necessary I think). Please vote for all applicable entries, e.g. "should apply only to new comments" + "\n- should translate into <br>-". Note that the order is randomized so binary choices cannot be grouped.
