Incorrect phpdoc in project_issue_state

In issue.inc, we have a function project_issue_state(). The function declaration includes a parameter $current_sid, however the phpdoc for the function does not mention this parameter.

**
 * Return information about project issue state values.
 *
 * @param $sid
 *   Integer state id to return information about, or 0 for all states.
 * @param $restrict
 *   Boolean to determine if states should be restricted based on the
 *   permissions of the current user.
 * @param $is_author
 *   Boolean that indicates if the current user is the author of the
 *   issue, which can potentially grant a wider selection of states.
 * @param $defaults
 *   Boolean to request the states used for default issue queries.
 *
 * @return
 *   An array of states (sid as key, name as value) that match the
 *   given filters, or the name of the requested state.
