You're right. Please run the regression tests on you machine to make
sure they pass, and I'll do the same, meanwhile, I hope Michael can
have a look at it and tell us what he thinks about your patch.

I am disillusioned enough to know that no man's opinion on any subject
is worth a damn unless backed up with enough genuine information to
make him really know what he's talking about.
