Render more of the markdown seen in readmes

A line of equals signs or dashes under a paragraph now makes a heading
of it, as on GitHub, instead of running into its text, and any other
rule ends the paragraph. Four spaces or a tab start a code block, and an
escaped pipe stays in its table cell. A link opening with two slashes
or backslashes in any mix leads to another site, so it renders as text
like the plain scheme relative one already did.
