Putting on my sysadmin hat, I am somewhat baffled by this  
discussion.  Completely hiding unknown groups?  I would print  
numerically and return a nonzero exit status (the latter possibly  
overrideable for OpenAFS use where they are expected); hiding them  
completely isn't just a way to annoy OpenAFS users, it also hides a  
clue to a system configuration problem (namely, missing groups in the  
group database).

If someone actually needs the hiding behavior, make it an option  
(possibly invokable via an environment variable).
