Bug in language privileges

Howdy,

I believe there is a bug in assigning language privileges.  When 
attempting to grant privileges, all actions use REVOKE instead of GRANT.  For that matter, when viewing a language's
detailsin the SQL pane, 
 
all privileges are displayed as REVOKE rather than GRANT though the ACL 
in the Properties tab says otherwise.

For example...

SQL pane:

-- Language: plpgsql

-- DROP LANGUAGE plpgsql;
 CREATE TRUSTED PROCEDURAL LANGUAGE 'plpgsql'  HANDLER plpgsql_call_handler  VALIDATOR plpgsql_validator;
REVOKE ALL ON LANGUAGE plpgsql FROM sa;
REVOKE ALL ON LANGUAGE plpgsql FROM "\""Server Administrators\""";
REVOKE ALL ON LANGUAGE plpgsql FROM gateway;

ACL from Properties:

{sa=U/sa,"\"Server Administrators\"=U/sa",gateway=U/sa}

Thanks,
Bborie
