Based on the behaviour of str and the fact that overriding unicode.__repr__ 
works just fine, I'd say file a bug on SF.

I think this bit in PyUnicode_Format needs to use PyUnicode_CheckExact instead 
of PyUnicode_Check:

             case 's':
	    case 'r':
		if (PyUnicode_Check(v) && c == 's') {

The corresponding code in PyString_Format makes a call to _PyObject_Str which 
deals with subclasses correctly.
