S(s�Fixer for __metaclass__ = X ->
(future.utils.with_metaclass(X)) methods.

   The various forms of classef (inherits nothing, inherits once, inherints
   many) don't parse the same in the CST so we look at ALL classes for
   a __metaclass__ and if we find one normalize the inherits to all be
   an arglist.

   For one-liner classes ('class X: pass') there is no
indent/dedent so
   we normalize those into having a suite.

   Moving the __metaclass__ into the classdef can also cause the class
   body to be empty so there is some special casing for that as well.

   This fixer also tries very hard to keep original indenting and spacing
   in all those corner cases.
