Think Taylor series, which is what you are asking for: it's
the derivative of the function with respect to the last argument.
This is poor notation on Mathematica's part, I think, since it's
trying to say "0th" derivative with respect to the first two
arguments, with the 2nd argument a 2-element list. Evaluate
D[f[{a},{b,c},d],d] for better notation.
