     Oops.  After discovering the hard way that the list is not completely
open (i.e., a subscription is required in order to post), I subscribed and
then reattempted to post what I had tried to post earlier, but forgot to
delete the final request above.  Just ignore it; there's no need to send a
copy to me directly.  Sorry for any confusion.
