It is possible (and seems so, from messages in this thread) that bash allows
a return in the trap string (not in a function called in that string) if the
trap occurs while executing a function (then the return applies to that
function).
Every shell allows this. Since the trap `action' is processed as if it were
invoked as `eval action', a return directly in it -- and not in a shell
function that `action' executes -- applies to a function that was executing
when the trap was executed.
