sympy/sympy — pull request #752 by goodok (2011-11-24 11:05:42+00:00)
Title: Remove fails of tests in master.

1. weakening doctest in Add.as_coeff_add

`(7 + 3*x + 4*x**2).as_coeff_add()`
`(7, (3*x, 4*x**2))
to:

`(7 + 3*x).as_coeff_add()`
`(7, (3*x,))`

Becouse has fails in Python-3.2 (lynux 64), and may be in other platforms.

It is identical to PR 751, but added a XFAIL test for this case.

2. Revert importing of the latex_ex module in sympy/galgebra/GA.py.

From:

import sympy.galgebra.latex_ex as tex

In Python 2.6 (AttributeError: 'module' object has no attribute 'latex_ex')

to:

import sympy.galgebra.latex_ex

with apropriated usage of this module further.
