emptiness check fails in query.php

[nbachiyski]

'Problem':

If an array is passed to wp-includes/query.php, the $query variable is never empty, because the array is no empty. However there are a lot of empty($query) check further in that function.

Solution':

We construct the query out of the non-empty keys of the array.

Punting.

I believe the current code in query.php fixes this as it does a check at the top on not empty and looks at arrays.

Please re-open if I am wrong.
