I execute multiple jobs and found in history table `pt_osc_history` all records with one value in `new_table_name` field.

In script I see:

```auto
$ tail -n +9797 pt-online-schema-change | head -n 6
   if ( $o->get('history') ) {
      my $sth = $cxn->dbh()->prepare(
         "UPDATE ${hist_table} SET new_table_name = ?"
      );
      $sth->execute($new_tbl->{tbl});
   }

```

Update operation set one value for all recors. This is not corrected. Or corrected?
