A second LookWord list look in a directory refills its +Search, as a terminal's word looks already did, rather than stacking another

Each word looked at with LookWord list opened a +Search of its own in
the same directory. Word looks now share the directory's one, the next
word refilling it; a `/` search still keeps a +Search each.
