    Do not use tmoveto in tputtab.
    
    tmoveto resets CURSOR_WRAPNEXT.
    
    Simple testcase:
    
    for i in $(seq 1 200); do
            printf '\t.';
            usleep 100000;
            printf '\t_AT_';
            usleep 100000;
    done
    
    In st executing this script causes _AT_ and . to overwrite each other in
    the last column.
