[sage-devel] buglet in maxima list

I discovered a small bug in sage 2.4.2 in the handling of maxima
lists.
When iterating over a maxima list there is an off by one error.
Individual
item access works fine.

I think the bug is actually in the implementation of
ExpectElement.__iter__
which strangely starts iterating from 1!

================ Example =======================
sage: v = maxima('create_list(i*x^i,i,0,5)')    #exampe from manual.
sage: for i in v:
    print i
....:
x
2*x^2
3*x^3
4*x^4
5*x^5
