Newsgroup discussion about the devnull tournament which started
today has pointed out that ``d4294967296$'' would cause getobj() to create
a gold piece object with quantity 0 which then got dropped to the floor.
(It's specific to gold; other types of objects don't behave that way.)
Also, wrapping which went past negative and zero all the way to positive
again (like 429496729*10+7, yielding 1) wasn't detected.
