      Description

      When assigning roles to a course the script /admin/roles/assign.php first give a quick summary of roles and the
      current number of users having these roles.

      Unfortunately the numbers are wrong , and do not match what is seen when getting role's details, since the called API function lib/accesslib.php/count_role_users do not filter out deleted users, i.e. users having the flag deleted set ...

      current SQL is :

      $SQL = "SELECT count
      FROM {$CFG->prefix}role_assignments r
      WHERE (r.contextid = $context->id $parentcontexts)
      AND r.roleid = $roleid";

      where it should be :

      $SQL = "SELECT count
      FROM {$CFG->prefix}role_assignments r,{$CFG->prefix}user u
      WHERE (r.contextid = $context->id $parentcontexts)
      AND r.roleid = $roleid
      AND r.userid=u.id
      AND not u.deleted";

      According to phpxref , this function is called only from admin/roles/assign.php, so this patch should be without other consequences.

      Cheers.
