Should G_list_element (src/libes/gis/list.c) be changed? Currently it
has:

    if (isatty(1))
    {
	more = G_popen ("more","w");
	if (!more) more = stdout;
    }
    else
	more = stdout;

I would have just gone ahead and changed it, but then I thought that
there might be a specific reason why $PAGER wasn't being used here.
