There is a special case for the assignedto attribute of
an issue in the method make_index_link of the class
Client in cgi_client.py in version 0.4.1 of roundup --
I am trying to use a database that does not use
assignedto -- a similar attribute is called
'responsible'. I have updated my instance_config.py
accordingly, but achieving the same special effect of
inserting the logged-in user instead of None in the
FILTERSPEC required me to override
Client.make_index_link in interfaces.py, I consider
this a bug, there should be some way of inserting
dynamic filtering rules in the FILTERSPEC (and probably
other parts of the instance_config, too) without having
to override whole methods of the cgi Client.
