If you really need this particular feature, you might want to consider the

(tac1; first N [tacN]).

I will try ssreflect. I am using the trunk version of Coq, so I note that the latest ssreflect sources are at: https://gforge.inria.fr/scm/viewvc.php/trunk/Saclay/Ssreflect/?root=coq-contribs. However - how is this downloaded? It doesn't work to git clone that address, or use it as an svn source repository.
