OK, I think that this is an improvement in
the overall appearance of this proposition.

Characterizing affine algebraic spaces by vanishing of cohomology
If X is a qc + qs algebraic space and H^1 of any quasi-coherent
module on X is zero then X is an affine scheme. The hard part of
the proof is to show that X is separated, since then it follows
in a rather straightforward way that X is quasi-finite over
Spec(O(X)) and we can use an earlier result (namely that a qf +
sep morphism is representable).
Let me know if there is a much easier way of doing this. Even in
the Noetherian case it doesn't seem easy to me.
