Right. The "nviz" script doesn't invoke g.parser. It invokes
{{{
"$GISBASE/etc/nviz2.2/nviz" -f
"$GISBASE/etc/nviz2.2/scripts/nviz2.2_script"
}}}
and the nviz binary calls G_parser() (with argv[0] set to Tcl's $argv0,
which is the name of the script).
One solution is to simply force argv[0] to "nviz" unless script_mode is
set.
