...where the "bOk = false" from the leading "if" is always overwritten in the
following check of "bOk = sTableRange == _sUpdateTableName".  The code had been
effectively like that ever since it got introduced with
4ae41a46 "INTEGRATION: CWS dba30," but it looks
broken.  I assume the two checks of "sTableRange == _sUpdateTableName" for
pNode->GetChild(0) and pNode->GetChild(2) shall only be done if the leading "if"
is not hit.  (And one remaining uncertainty is if really only one of those
"sTableRange == _sUpdateTableName" checks needs to be true or if both should be
true for bOk to be true.)
