2. Tweak the paragraph wrapping in `generate()` so that all
      paragraphs in a multiple-paragraph item/blockquote will
      be properly wrapped with `<p>`...`</p>` (or whatever is
      appropriate.)
   3. Attempt to follow indentation better inside lists, so
      a list item with multiple paragraphs is parsed correctly
      when the second (& up) paragraphs are indented the same
      as the first paragraph.
