Bug 971 records "NeedInfo" becoming "Needs Info" in January 2006. And bug 50663 records a pre-implementation call where "Needs Info" became "Incomplete" in July 2007. It's not clear why that happened (though Jeroen might remember), but it was simultaneous with the introduction of the "(without response)" and "(with response)" pseudo-statuses.
