Where is the k coming from?!!

It looks like it happens with variables starting with 'd', 'f', 'g', and
'h':
sage: v=var(",".join(['%s1'%i for i in 'abcdefghijklmnopqrstuvwxyz']))
sage: v
(a1, b1, c1, d1, e1, f1, g1, h1, i1, j1, k1, l1, m1, n1, o1, p1, q1, r1,
s1, t1, u1, v1, w1, x1, y1, z1)
sage: for i in v:
....: i.full_simplify()
....:
a1
b1
c1
factorial(k + 2*n - 1)/factorial(2*k + 4*n)
e1
factorial(n)/(factorial(-k + n)*factorial(k))
(-1)^k*k/(4*k^2 - 1)
x^k*factorial(n)/(factorial(-k + n)*factorial(k))
i1
j1
k1
l1
m1
n1
o1
p1
q1
r1
s1
t1
u1
v1
w1
x1
y1
z1
Thanks,
