Merge pull request from doerwalter/master Fix pretty printing dispatch. This patch fixes a problem mentioned here: http://mail.scipy.org/pipermail/ipython-dev/2012-March/008874.html Search for the best method to use for pretty printing an object now no longer prefers any registered printer in `type_printers` for the class or any of the base classes over a `_repr_pretty_` method defined in the class or any of its base classes. Instead the mro is walked, looking for both registered printers and `_repr_pretty_` methods, so that the inheritance hierarchy will be taken into account.
