  data0type.ic:
    Change the sorting order of TEXT columns in InnoDB: pad with spaces at the end in comparisons; we MUST UPDATE the MySQL MANUAL to warn about the need to rebuild tables (also MyISAM) in certain cases in an upgrade to 5.0.3; TODO: study what complications the missing DATA_BINARY_TYPE flag in InnoDB < 4.0.14 causes: we would compare then also BLOBs with space padding, not just TEXT
