Comment (by dsm):
Okay, this looks good. Two copyedits, an extra doc describing the
behaviours of the derivative function, some tests making sure we can't
differentiate with respect to the branch number, and the addition of
lambert_W(-pi/2) = pi/2*I as a special value.
I give positive review to the preexisting parts of v8; if the new bits of
v9 look okay I think we're good to go.
