[New-bugs-announce] [issue18929] inspect.classify_class_attrs ignores metaclass

[Ethan Furman]

New submission from Ethan Furman:

Part of the solution for Issue18693 is to have `inspect.classify_class_attrs()` properly consider the metaclass (or type) of the class when searching for the origination point of class attributes.

The fix is changing line 325:

-        for base in (cls,) + mro:
+        for base in (cls,) + mro + (type(cls),):

or line 361:

-    return cls.__mro__
+    return cls.__mro__ + (type(cls), )

Should we target previous Pythons with this fix?
