Right, this is a feature gap in the new newgrp. It does not support
passing a command and will instead spawn a new shell. That also
explains the "exit code" of 0, as in the new shell there was no
previous program.

As a stop-gap I've removed the sg -> newgrp symlink.

I would appreciate help typing in the additional code and submitting
that to upstream, so we don't have to diverge from upstream forever.

I'm sorry about this oversight.

Best,
Chris
