I made this change because Export made all integer data for ENUM unescapated. And this means position of value in ENUM definition and not a data.
Example:
columnname enum('0', '1', '2') ...
insert into tablename (columnname) value (0) ... means error, becouse 0 here is integer and MySQL means, it is position 0 in ENUM, but positions in ENUM are indexed from 1.
Right:
insert into tablename (columnname) value ('0') ...
