I too think that should be the behavior, but who knows what
the intention was.  If the behavior gets fixed to do that
then great.  In any case (fixed behavior, intended but not
yet fixed behavior, or current behavior), I think the
behavior should be documented.

Right.  Shall we leave this bug open for that enhancement
request, or do you want a new report for just that?
