However, no other characters may occur at the end or the beginning:
Example 16
_ _ _ _ a a------
This seems overly specific. Why not “no other characters may appear in the line”, with a third example:
--- a ---
Or is this allowed?

The spec doesn’t need to stand alone. You can (should) use the dingus at http://jgm.github.io/stmd/js/ to answer this kind of question. That said I’ll try to add some specifics…
--- a ---
is allowed, it’s just not interpreted as a horizontal rule.
Good comment. I’ve improved the example.
