issue owner does not receive email notifications on follow-up

When a user submits a new issue, and someone else creates a follow-up on that issue, then I believe that an email notification should be sent to the user who submitted the issue. But unfortunately, he only gets an email if the submitter has used the "subscribe" form, which is not likely because the form is pretty difficult to find.

To fix this, I automatically subscribe the issue author to "own issues".
I have patched the "issue.inc" code and added an "autosubscribe" function:

/**
 * Automatically subscribe user to "own issues" in the specified project. Called when user creates an issue, because
 * without this subscription he won't receive an email when someone else posts a follow-up on his issue.
 *
 * @param $uid
 *   userid
 * @param $pid
 *   projectid, or actually nid for the node where nodetype = "project", not "issue"
 */
function project_autosubscribe($uid, $pid) {

   $level = db_result(db_query('SELECT level FROM {project_subscriptions} WHERE nid = %d AND uid = %d', $pid, $uid));
   if ((1==$level) || (2==$level)) {
      // no action required, this user is already subscribed to this project
   }
   else {
      db_query('DELETE FROM {project_subscriptions} WHERE nid = %d AND uid = %d', $pid, $uid);   	
      db_query('INSERT INTO {project_subscriptions} (nid, uid, level) VALUES (%d, %d, %d)', $pid, $uid, 1);
   }
}

... and this new function is called from functions "project_issue_insert" and "project_issue_update" just before calling mail_notify :

  project_autosubscribe($node->uid, $node->pid);
  if ($node->assigned)
    project_autosubscribe($node->assigned, $node->pid);
  project_mail_notify($node);

I hope this makes sense, and also hope that it will be added to the CVS repository for future releases?
