Support list items starting with a blank line

Browse Source 
According to the CommonMark specs ([list items](http://spec.commonmark.org/0.26/#list-items), rule 3), list items starting with a blank line basically behave like as if the \n doesn't exist. Also see example [#241](http://spec.commonmark.org/0.26/#example-241).
