After giving it some though I arrive at a conclusion that picking a different breaking point for your line when it creates a list/bold ambiguity is a much simlier and easier to exmplain technique than any escaping. And since the newlines are ignored anyways, it doesn't constrain the possible output.

I like this idea, but do any wiki engines currently implement multiline list items?  I'm afraid of violating the principle of [[Not New]].

I'm not an expert, but the first engine I've tried,
[[http://www.oddmuse.org]], supports it.
