Comment (by SimonKing):
Yessss! The following is ''without'' the patch. Hence, what we see here is
an existing bug, that did not show up by mere coincidence (different
ordering of the doctests)!!
I can trigger it on the command line (with sage-5.6.rc0 without the patch
from here):
{{{
sage: F = CombinatorialFreeModule(ZZ, [1,2,3], prefix="F")
sage: G = CombinatorialFreeModule(ZZ, [1,2,3,4], prefix="G")
sage: f = F.monomial(1) + 2 * F.monomial(2)
sage: g = 2*G.monomial(3) + G.monomial(4)
sage: tensor([f, g]) # indirect doctest
2*F[1] # G[3] + F[1] # G[4] + 4*F[2] # G[3] + 2*F[2] # G[4]
sage: F = CombinatorialFreeModule(ZZ, [1,2,3], prefix='x')
sage: G = CombinatorialFreeModule(ZZ, [1,2,3,4], prefix='y')
sage: f = F.monomial(1) + 2 * F.monomial(2)
sage: g = 2*G.monomial(3) + G.monomial(4)
sage: latex(tensor([f, g])) # indirect doctest
