The doc says:

        The returned list contains tuples of the 
form

            (date, tag, action, params)

        'date' is a 
Timestamp object specifying the time of
             the change and
        
'tag' is the journaltag specified when the database
             was 
opened.

but it calls getjournal that returns a 5-ple of:

  
(nodeid, date.Date(date_stamp), user, action, 
params)

Basically add nodeid to the front of the 4-ple 
and
you are all set.

This is a problem in 
roundup/backends/
rdbms_common.py and back_anydbm 
but not a problem
in back_metakit since there is no doc string.
