Fixed nested <pre>-blocks problem.

    # Formats doc-comment for placement into HTML.

    # Renders it with Markdown-formatter and replaces @link-s.

    def format(input)

      # In ExtJS source "<pre>" is often at the end of paragraph, not

      # on its own line.  But in that case RDiscount doesn't recognize

      # it as the beginning of <pre>-block and goes on parsing it as

      # normal Markdown, which often causes nested <pre>-blocks.

      #

      # To prevent this, we always add extra newline before <pre>.

      input.gsub!(/([^\n])<pre>/, "\1\n<pre>")

      replace(RDiscount.new(input).to_html)
