[issue1109] Warning required when calling register() on an ABCMeta subclass

[Guido van Rossum]

Guido van Rossum added the comment:

Please roll this back.  The error message you added is inappropriate
when the parameter to a legitimate register() call is omitted, e.g.

collections.Sequence.register()

Since we got rid of unbound methods, the infinite recursion is gone;
that's a good enough fix, there are tons of other situations where
confusion between class and instance (or between metaclass and class)
causes confusing error messages.
