Attaching trivial patch. I've pushed the example above as a dtest too.

Btw, the patch kind of fix another small issue in that in the example above, results ended-up not ordered following the IN order, which we do it otherwise (since there is no ORDER BY on c1, only on c2).

> That's not a very common mix but well, the following return no results which is obviously bogus:
> {noformat}
> CREATE TABLE test (k int, c1 int, c2 int, PRIMARY KEY (k, c1, c2));
> INSERT INTO test(k, c1, c2) VALUES (0, 0, 0);
> INSERT INTO test(k, c1, c2) VALUES (0, 0, 1);
> INSERT INTO test(k, c1, c2) VALUES (0, 0, 2);
> SELECT * FROM test WHERE k=0 AND c1 = 0 AND c2 IN (2, 0) ORDER BY c1 DESC
> {noformat}
> Note: it's pretty useless to order on a column which has an equal restriction, and that's probably why nobody ran into this yet, but that's really just due to a minor typo so there is no reason not to fix.
