Bug#18250 (Truncate table replicate both as statement and as individual

           rows for SEs using injector):
Table truncation ("DELETE FROM t1" and "TRUNCATE t1") was logged as
a statement even when the storage engine deletes the rows individually
using the injector.


sql/sql_delete.cc:
  Don't log a truncate statement if the storage engine is using the injector.
