I suppose I wouldn't have to hard-code the whole list to do that...
okay, here's a slightly silly Mark 2 version.  I've added the other
software-related sites to the packagename-completion set on the
grounds that it's better than the fallback of using dictionary

If you want easier completion on the common options, why not give
them each a unique initial letter?
	-c(ensored, ie non-p0rn),
	-l(ist, ie elvi),
	-n(oisy, ie non-silent),
	-r(aw, ie non-escaped)
	-s(ilent, ie quiet),
