[cvs-nhc98] patch applied (hat): Permit hat-trail to display parent-colouring correctly.

Fri May 18 04:02:40 PDT 2001 malcolm * Permit hat-trail to display parent-colouring correctly. To achieve this, we add an extra field to most of the messages sent from hat-connect to hat-trail. This field contains a prediction (obtained via the new routine peekTrace()) of the node number that will eventually be the /displayed/ parent for a particular node, i.e. by skipping over Hiddens and Sats and following the left pointer of Indirections.
