Can't handle backslash and bracket

[jirikuncar]

I have found a following imports that can't be automatically sorted:

from sympy import S, pi, GoldenRatio as phi, sqrt
from sympy.ntheory.continued_fraction import \
    (continued_fraction_periodic as cf_p,
     continued_fraction_iterator as cf_i,
     continued_fraction_convergents as cf_c,
     continued_fraction_reduce as cf_r)
from sympy.utilities.pytest import raises

Results to:

from sympy import GoldenRatio as phi
from sympy import S, pi, sqrt
from sympy.ntheory.continued_fraction import \
    continued_fraction_periodic as cf_p
from sympy.utilities.pytest import raises

     continued_fraction_iterator as cf_i,
     continued_fraction_convergents as cf_c,
     continued_fraction_reduce as cf_r)

Working on a fix for this at Pycascades sprints!

@katlings thank you!
