The object U constructed in Lemma tag 017M was not Hom(\Delta[k], X) but
equal to Hom(C[k], X) where C[k] is the cosimplicial set constructed
dually to the construction of \Delta[k]. This snafu actually had some
ramifications for later work, including the proof of an important lemma
in the chapter on hypercoverings...
