New issue 1244 by sophie.duriez: (x + exp(x)).is_positive returns True
http://code.google.com/p/sympy/issues/detail?id=1244
When x is real, (x + exp(x)).is_positive returns True :
>>> x = sympy.Symbol("x", real=True)
>>> (x + exp(x)).is_positive
True
it should report 'None' instead (unless x is positive itself)
