Hello,If there is still interest, here's an updated patch, against the latest version, of adding these features to join+uniq:
http://lists.gnu.org/archive/html/coreutils/2013-02/msg00082.htmlThe patch has been re-created (not just rebased), because the old one caused few conflicts. Functionally it is the same as before, and all tests pass.
Comments are welcomed, -gordon
