AsciiDoc writer: use doubled delims in more contexts.

Also escape the `#` character.

Closes #11362.

An alternative solution, raised in #11362, would be to
rely less on escaping and simply always use doubled delimiters.
However, there would still be a need for escaping, since one
might use a literal `##` (for example)>
