Oops, thanks for spotting that.  I'm not sure whether it is safe to abort 
these calls as soon as the first one fails, but perhaps I could introduce 
some more variables, and test them all afterwards.

What should I do with the big patch?  Resend it with this cut out?  Or, 
considering that I might have overlooked something else, send 90 some 
little ones?

thanks,
