> If a value is repeated within an IN clause then repeated rows are returned for  the repeats:
> cqlsh> create table t1(c1 text primary key);
> cqlsh> insert into t1(c1) values ('A');
> cqlsh> select * from t1;
>  c1
> ----
>   A
> cqlsh> select * from t1 where c1 = 'A';
>  c1
> ----
>   A
> cqlsh> select * from t1 where c1 in( 'A');
>  c1
> ----
>   A
> cqlsh:dslog> select * from t1 where c1 in( 'A','A');
>  c1
> ----
>   A
