Hello, I have some questions with the Heading.  
When I have a word less than 3 characters, the Heading does bot work with it. For example:

I have to add a “-” to make the heading apply:

I am not sure this is a bug. Anyone could explain this?  
Thanks

It is an excellent [CommonMark](http://commonmark.org/) compliant engine. I expect quite a few edges to be found during this period of testing. Do not open bugs about the new Engine, just reply here. I/we will be updating the top post here with the list of issues and striking out stuff as it is fixed.
