Actually, the fact that the join is broken has the advantage of making
it more clear that this is an improper wrap. It is /better/ to break
there than at a disjoint boundary.

The purpose of "word-wrap: break-word" is to handle emergency cases,
where there are no other breakpoints. It does not insert hyphens. It
does not consider morphemic, syllabic, or other boundaries. It just
breaks somewhere arbitrary to avoid overflow.

So I disagree with your suggestion and believe the spec is correct
as it stands.
