Thank you thank you!  You can credit it to 105440, please, if you
don't mind supporting America's most aggressive defender of firearms
ownership.  It's tax deductible, too.

Interesting.  Oh well, either 31.1034768 or 31.103477 is better than
31.103.  Probalby my calculator was chopping off digits.

Right, the actual practical difference is very very small, but it is a
systemic bias, which is bad, even if it is small.  e-gold has over a
ton in circulation, so being off by even one part in 100,000 does add
up to something real.

Thanks for fixing this!
