fix formatted text parsing

earlier, situations when there were strings like 'bold\ntext\n' that
needed to be treated as bold text were converted in a wrong way (e.g.
like '**bold\ntext\n**', which is breaking markup because of newline
characters before closing asterisks), but now it's kind of fixed.

also there's now support for emails and <pre> blocks.
