Fixed a limitation bug in mysqlimport. sql_statement was designed to

contain max 1280 characters, but sometimes in rare cases when --columns
was used, more than 1280 characters was needed. This is case when a lot
of columns was specified using this option. Raised the max value to 8448,
which should be enough.
