Thank you!  I could never find that code without your help.

I was hoping that my patch (below) would fix my problem while honoring
the spirit of your code, but it turns out to have no effect at all,
either good or bad.

I hope you can see what I was trying to do and explain why it fails.

Keep in mind that I'm not a c(++) programmer, so my error might be as
trivial as incorrect syntax.  (I can't afford the hours it took me to
test the patch, just to experiment with syntax :)

Many thanks!
