Prior to this change, there were double-colon ("::") characters in the
HTML docs to indicate literal blocks.
The proceeding paragraphs were not pre-formatted because there was no
newline between the double-colon and the to-be-pre-formatted paragraph.
Move the "::" characters inline to simplify the syntax and make Sphinx
properly interpret these texts as literal blocks.
