Fix this one broken doctest and this gets a positive review from me:
{{{
#!python
wst...@sage:~/build/sage-4.1.2.alpha1$ ./sage -t
devel/sage/sage/misc/functional.py
sage -t "devel/sage/sage/misc/functional.py"

line 442:
sage: sum(k * binomial(n, k), k, 1, n)
Expected:
1/2*2^n*n
Got:
n*2^(n - 1)
**********************************************************************

line 480:

Expected:
Traceback (most recent call last):

ValueError: Sum is divergent.
Got:
-a/(q - 1)

The above is just the result of changes in Maxima going from 5.16 to 5.19
in sage-4.1.2.
