[GRASS5] nviz problem

[Huidae Cho]

Hi,

Now nviz is not a *wish script but a shell itself. That's why it prints
a prompt and we cannot execute it background and inside "d.m &". To fix
this problem, I think we should go back to NVWISH because running nviz
foreground is pain.

You can test this:

	wish &

prints % prompt and just stop!
