    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@';
        usleep 100000;
    done
    
    In st executing this script causes @ and . to overwrite each other in
    the last column.
