No bullets show unless list preceded by blank line

Moved from https://github.com/dpeek/dox/issues/124

I believe this markup should show a bullet:

``` haxe
/**
* Some comment
* - Some bullet
*/
```

But instead it renders like this: `Some comment - Some bullet`.

Adding a blank line in between the comment and the bullet list restores the bullet.

_GitHub markup dramatization:_

Some comment
- Some bullet
