IF you put {{special:prefixindex}} on a page, you're presented with a box asking you for the prefix. I think in the case where its included, it makes more sense to not have the input box, and just display all pages as if the empty string was the prefix.

Also the allpages link in upper-right corner of http://en.wikipedia.org/wiki/Special:PrefixIndex/foo is probably misnamed, now that doing special:prefixindex by itself doesn't show all pages. (maybe there should be a parameter to actually show all pages in that case or something, or maybe the message should be removed).
