Subject: [PATCH] Checks for metaclass's __repr__ in _type_pprint

RepresentationPrinter has a type pprinter for 'type' subclasses. It will
thus be called to print a class object (instance of 'type), avoiding the
__repr__ of the metaclass.

This patch checks for an overridden __repr__ before using the custom
type-representation logic.
