Of those two choices, I prefer the former. I don't like the idea of expanding the set of conforming comments, because I think having conforming comments should maximize the backwards-compatibility of the comments (and there are browsers in the wild that implement SGML- style comments, which is incompatible with the latter alternative above).

I think allowing paired double hyphens with whitespace in between and allowing whitespace between the ending "--" and ">" would make sense. This would improve the source-level upgradeability of valid HTML 4 to conforming HTML 5. However, it would have the old confusion issues.
