Here are my recommendations for the 0.4 draft:

* Newline within a paragraph is whitespace, not linebreak.

* Explicit "{{{\\}}}" for linebreak ("{{{%%%}}}" would also be fine).

* Closing curly braces group to inside of inline pre markup.

* "\}}}" escape within block pre markup (tilde would also be fine).

* "|*" for headings within tables.

* Whitespace needed after list bullet (disambuguate from bold).

* Use ":" (parse similarly to "*" and "#") for indented blocks.
