Yeah, I never understand that either. But it's easily fixed:

h = Hpricot('<a/><b>c</b>', :xml => true)
h.to_s => "<a></a><b>c</b>"

I think it's because when you don't define :xml as true, then Hpricot
acts as an *HTML* processor, and therefore tries to correct bad HTML..
and somehow ends up with the badness of wrapping the empty element.
