False positive for W0602

Mini-example:

#!python

path = None

def junk():
    global path
    from os import path

def junk2():
    print("%s" % path)

Pylint reports W0602 (global-variable-not-assigned) for the statement "global path".

But actually, path is assigned to by means of the import statement as can be seen by the interpreter interaction below:

from junk import *
junk2()
None
junk()
junk2()
<module 'posixpath' from '/usr/lib64/python2.7/posixpath.pyc'>

Without the global statement the second invocation of junk2() would print None, just like the first.

The interpreter interaction from previous comment, better formatted:

#!python

>>> from junk import *
>>> junk2()
None
>>> junk()
>>> junk2()
<module 'posixpath' from '/usr/lib64/python2.7/posixpath.pyc'>

This had the same solving as issue #196.
