Even in the most recent version, "d.zoom" requires a "rast=" option
unless something is already displayed in the monitor (according to
D_get_{cell,dig,site}_list()):
if(!rast && !vect && !site)
{
rmap->required = YES;
just->answer = 1;
}
This should probably be replaced by a check *after* G_parser()
returns, e.g.
if(!rast && !vect && !site &&
!rmap->answer && !vmap->answer && !smap->answer)
G_fatal_error("Nothing to zoom");
