I don't quite understand the problem.  Are you saying you need the new
shell to be a login shell if the old one was?  You could try something
like this:

newgrp () {
  local args;
  [[ -o login ]] && args=-
  exec =newgrp $args $*
}

If that's what you want I'll change the FAQ.

(Just in case it helps:  if you have changed $SHELL, it looks like
newgrp won't honour it, it will go back to the passwd entry.)

Bonne chance.
