I guess I have mixed up two different things above.

From my point of view, the first thing to do is to decide is if this
`backward-sexp' behavior is a bug or not.  So this comes down to if we
think that "---" should be treated as a delimiter, just as " - " is, in
the context of ELisp docstrings.

I don't have a strong opinion either way, but I did find the current
behavior somewhat surprising when I saw it.

On the other hand, even if this is a bug, it might very well not be
worth fixing as the "---" delimiter is not very commonly used.
