Word count assigned to last node editor instead of node creator

Not really a bug I think, depends on how you use your drupal installation. In my case, users post comments and editors review and fix formatting, misspelling and others errors. When this happends, a new node revision is created with the editor ID as author BUT, the node content was created by node creator, and I want to asign node count to node creator.

Word count algorith asigns this nodes to the last editor, and I fixed this changing nodes SQL select query to :

SELECT nr.title, nr.body, n.uid, u.name FROM {node_revisions} AS nr INNER JOIN {node} AS n ON nr.vid = n.vid INNER JOIN {users} AS u ON n.uid = u.uid

Hope this helps
