Log Message:
Checking in my fix to the interface package from zope-2_7-branch to zope-2_6-branch.
I applied a patch to Implements.py some month ago to fix nested interfaces but I forgot to check it into this branch. Because of the missing fix some interface tests were broken on Zope 2.6.x. Thx to Stefan Holek to point me on this problem.
