mistakes lists bullets for headings in markdown

[masukomi]

in markdown:

if i make a list with * for each item instead of - it thinks they're each a top level heading.

I.e.

# foo
hey 

* bar 
* baz

should generate a TOC that only contains a single line item for foo

currently you need to use - for your list items in order to get the desired result.

That should do it. Please check, if you have a chance
