 /**
  * list all watchers of a page
  *
  * If the page is public or restricted to any member, the full list of persons watching this
  * page, and its parent section. If the parent section has the option 'forward_notifications'
  * the persons assigned to grand parent section are added.
  *
  * For example, if the root section A contains a section B, which contains page P, and if
  * P is public, the function looks for persons assigned either to B or to P.
  *
  * If the parent section has option 'forward_notifications', then this fonction adds watchers
  * of grand-parent section to the list.
  *
  * If the page is private, then the function looks for wtahcers of it, and for editors of the
  * parent section that may also be watchers.
  *
  * For example, if the section A is public, and if it contains private page P, the function
  * looks for watchers of P and for editors of A that are also watchers of A.
  * This is because watchers of section A who are not editors are not entitled to watch P.
  *
  * @param array attributes of the watched page
  * @param int the offset from the start of the list; usually, 0 or 1
  * @param int the number of items to display
  * @param string 'full', etc or object, i.e., an instance of Layout_Interface adapted to list of users
  * @return NULL on error, else an ordered array with $url => ($prefix, $label, $suffix, $icon)
  *
