That 80 column text page is a page that was saved from TV Tropes content purges in a plain text file with word wrap formatting and needs reformatted by having the content shifted back into proper alignment.
The double bullet points is another quirk of MediaWiki, though it's intentional. Ordinarily, if there is a single bulletpoint item above two ** marks, you'll only see single bullet points with proper spacing.
However, on pages with improper bulletpoint markup or a bad mix of bulleted and numbered lists, you'll see the screwed up version, meaning the listing needs manually corrected.
