Yes, I'll add some. I'm doing some general tidying up of the document  
module as it's full of some unnecessarily cryptic abbreviations but  
there's one section I don't understand:

for pt in self.paragraph_types:
     if isinstance(pt, sts):
         # grab the corresponding function
         pt=getattr(self, pt)
     # evaluate the paragraph
     r=pt(paragraph)
     if r:
         if type(r) not in sequence_types:
             r=r,
         new_paragraphs=r
         for paragraph in new_paragraphs:
             subs = self.color_paragraphs(paragraph.getSubparagraphs())
             paragraph.setSubparagraphs(subs)
         break

What is the function of the comma after r=r?
