LibMarkdown: Handle delimiter flanking with punctuation

Browse source 
This patch handles the following two rules
1) A delimiter run is either (a) not followed by a Unicode punctuation
   character, or (b) followed by a Unicode punctuation character and
   preceded by Unicode whitespace or a Unicode punctuation character.

2) A _ can be used to open/close a delimiter run if it's (a) not part
   of a left-flanking delimiter run or (b) part of a left-flanking
   delimiter run followed by a Unicode punctuation character.
