 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.
