The range() object is immutable, but is not atomic, and copy.deepcopy() shouldn't return it unchanged.

>>> class I(int): pass  # mutable index
... 
>>> import copy
>>> r = range(I(10))
>>> r2 = copy.deepcopy(r)
>>> r.stop.attr = 'spam'
>>> r2.stop.attr
'spam'

This is Python 3 only issue because in 2.7 the xrange() object doesn't exposes start/stop/step attributes.

Proposed patch fixes the copy module.
