Comment:
I've imported the patch, but currently there are three failing doctests:
{{{
Failed example:
whittaker_function(omega[1], w, -1, v)
Expected:
v^2*B[(-1, -1, 3)] + (v^2-v)*B[(-1, 1, 1)] + (v^2-v)*B[(-1, 0, 2)] +
(v^2-v)*B[(0, -1, 2)] + (v^2-2*v+1)*B[(0, 0, 1)]
Got:
B[(-1, -1, 3)] + (-v+1)*B[(-1, 1, 1)] + (-v+1)*B[(-1, 2, 0)] +
(-v+1)*B[(-1, 0, 2)] + (v^2-2*v+1)*B[(1, 0, 0)] + (-v+1)*B[(1, -1, 1)] +
(-v+1)*B[(0, -1, 2)] + (v^2-2*v+1)*B[(0, 1, 0)] + (v^2-2*v+1)*B[(0, 0, 1)]
