Error in AccessControl/Owned.py/changeOwnership

[Bug Importer]

Imagine you have a folder A and a subfolder A/B.

A's owner is user1, B's owner is user1 as well.

user2 should become owner of A but not of A/B.

But unchecking the "Also take ownership of all sub-objects" option doesn't work, user2 becomes owner of A/B as well.

Reason:

There's a little bug in AccessControl/Owned.py/changeOwnership:

The else part in the for loop changes ownership of children although "recursive" isn't set.
You just don't need the else part, and it works as desired.

This is now fixed by removing the "else" branch in the code:

Zope 2.12 branch: http://svn.zope.org/?rev=112514&view=rev

Zope trunk: http://svn.zope.org/?view=rev&rev=112513

The checkin that introduced the faulty behavior even carries a message saying the author did not really understand what he was doing at that point.
