Error description

  • The "Skipping Duplicate Lines" functionality has incorrect data
    in it.  It incorrectly has the previous line of data.  Below is
    an example.
    
    Msgdesc:
    0x0000:  4d442020 01000000 00000000 08000000  |MD  ............|
    0x0010:  ffffffff 00000000 22020000 00000000  |........".......|
    0x0020:  4d515354 52202020 ffffffff 02000000  |MQSTR   ........|
    0x0030:  === Skipping 17 Duplicate Lines ====  |MQSTR
    ........|
    0x0140:  00000000                             |....            |
    
    
    The trace formatter should print one of the lines unaltered and
    then the 'Skipping' line.  In an MQMD you would not have
    'MQSTR...'
    repeating over and over so this should look more like
    the following:
    
    Msgdesc:
    0x0000:  4d442020 01000000 00000000 08000000  |MD  ............|
    0x0010:  ffffffff 00000000 22020000 00000000  |........".......|
    0x0020:  4d515354 52202020 ffffffff 02000000  |MQSTR   ........|
    0x0030:  00000000 00000000 00000000 00000000  |................|
    0x0040:  === Skipping 16 Duplicate Lines ====
    |................|
    0x0140:  00000000
