[Zodb-checkins] CVS: Zope/lib/Components/ExtensionClass/test - test_acquisition.py:1.4

[Shane Hathaway]

Update of /cvs-repository/Zope/lib/Components/ExtensionClass/test
In directory cvs.zope.org:/tmp/cvs-serv32296/test

Modified Files:
	test_acquisition.py 
Log Message:
Corrected aq_inContextOf().   The former code returned the incorrect result
if the context object was the root of the hierarchy, a condition which
normally does not occur in Zope, but can occur in scripts.
