/**
 * Take a list of unescaped comment blocks and emit safely escaped HTML to
 * render it nicely with wiki-like format.
 *
 * Each block is a map with a type key. When the type is 'paragraph', or 'pre',
 * it also has a 'text' key that maps to the unescaped text content for the
 * block. If the type is 'list', the map will have a 'items' key which maps to
 * list of unescaped list item strings. If the type is quote, the map will have
 * a 'quotedBlocks' key which maps to the blocks contained within the quote.
 *
 * This mechanism encodes as little structure as possible in order to depend on
 * the Soy autoescape mechanism for all of the content.
