[Zodb-checkins] CVS: ZODB3/ZODB - POSException.py:1.17

[Barry Warsaw]

Update of /cvs-repository/ZODB3/ZODB
In directory cvs.zope.org:/tmp/cvs-serv19311

Modified Files:
	POSException.py 
Log Message:
UndoError() constructor now takes its arguments in reverse order,
i.e. reason first, then oid.  This is because there's always a reason
but sometimes there isn't an oid (so we can default arg the oid).
