My apologies gents, I was traveling and my email was not behaving
properly.  Did we reach a conclusion on this?  I¹m happy to use the patch
supplied or I could also change the warning just to a note if either of
you think I might be better to leave in for any reason?  Just let me know.
 Oh, I¹m re-attaching the patch because I think it may have been lost in
the shuffle from my first submission.  Thanks for your assistance.
