Mathematically axiom produces correct output now, however I'm not sure whether my patch is best possible.

Maybe there should be a function D in OutputForm that displays unevaluated differentiation. Also, I find it ugly to use the raw %diff operator in COMBF. Furthermore, is it necessary to substitute a dummy variable for the variable of differentiation?
