/* remove option which was put by mysql_explain_union() */
sl->options&= ~SELECT_DESCRIBE;
Above remove the flag, but in deference of INSERT/DELETE we do not (can not) use mysql_explain_union().

Without it, mysql_update() didn't know that there will be EXPLAIN result set and was sending OK at the end of the update, which conflicted with the EOF sent later by EXPLAIN.

First execution of Multi-update set OK, then explain set EOF.
