New Revision: 66837
Log:
#4069: aSet.remove(otherSet) would always report the empty frozenset([]) as the missing key.
Now it correctly refers to the initial otherSet.
Backport of r66836.

Core and Builtins
-----------------
+- Issue #4069: When set.remove(element) is used with a set element, the element
+ is temporarily replaced with an equivalent frozenset. But the eventual
+ KeyError would always report the empty frozenset([]) as the missing key. Now
+ it correctly refers to the initial element.

- Fixed C99 style comments in several files. Python is now C89 compatible
again.
