Incorrect API call when mass-deleting comments

When using the admin "Moderator actions" to bulk delete comments, the module makes an incorrect call to update the node_comment_statistics table. In antispam.module, line 1727:

_comment_update_node_statistics($comment->cid);

Should actually be a node id according to the API:

_comment_update_node_statistics($comment->nid);

Because the module wasn't passing the correct node id, the comment count value is not being updated on node objects. Can someone write a patch for this one-line change?
