Bug #53088: mysqldump with -T & --default-character-set set

Browse Source 
truncates text/blob to 766 chars

mysqldump and SELECT ... INTO OUTFILE truncated long BLOB/TEXT
values to size of 766 bytes (MAX_FIELD_WIDTH or 255 * 3 + 1).

The select_export::send_data method has been modified to
reallocate a conversion buffer for long field data.
