I'm delighted to see you write this. I've stared balefully at #ifError:
on a number of occasions and then backer away muttering soothing
inanities to placate it. The politest thing I could think of to say
about it would be YUCK. I do hereby proclaim my belief that you would be
doing a major service to the community if you could clean out (or
explain for others to follow) the 167 users of this heinous message.
