Update of /cvs-repository/Products/CMFCore/tests
In directory cvs.zope.org:/tmp/cvs-serv29799/CMFCore/tests

Modified Files:
      Tag: CMF-1_4-branch
	test_PortalFolder.py 
Log Message:


 - CMFCore.PortalFolder: Enforce check of "Delete objects" permission
   during cut + paste. (http://zope.org/Collectors/259)

   N.B.  This fix depends on an update to the underlying Zope software,
         e.g., Zope 2.7.3 or later.  Two new unit tests fail on
         Zope 2.7.2 and earlier.
