I didn't mean to exclude elements.  I meant that if attributes are
queried then we do want to include `class` and `id`, but if they're not
then we shouldn't change it just on the premise that `class` or `id`
could be added.

Right.

I don't think it adds a closing newline any more than the current
code does: you start with point in front of 2 newlines and you end with
2 newlines after </ol>.

Right.

Indeed, \n is the magic one while ?\n just inserts the LF char
without any extra processing (just like "\n").
