    fix mismatch of several esc seq. in one input
    
    scroll does not detect two esc seq. with scroll up/down
    command in the input buffer and handle it as regular input.
    By using strncmp(3) with strlen(3) of the matching sequence,
    we detect the fist command and irgnore the rest of the input
    buffer.
