Tab cannot be used in CSV filter

When the CSV option is selected, one can select the type of separator. Tab is one of the proposed one, but it seems to not have any effect.

See the original report here: http://tech.groups.yahoo.com/group/okapitools/message/1377

It would be better if it either be a) allowed and work, or b) be disallowed.
