Make it clearer what's happening with a fall-through.

An if () {...}'s close-brace was hiding on the end of a break; line,
an idiom used in several places for braces that existed to contain a
case (for the sake of local declarations).  This made it hard to see
that there was an if() whose else was the resulting (commented)
fall-through.  So put that close-brace on the comment's line and make
the comment clearly indicate it's an else.
