It sets the sse-Positions ...
(It is somewhat equivalent to StaffFinished,
with the difference, that assocpos is used). assocpos is the tail-position
of the associated list at the time of the pbreak-situation.
Now, this routine is called when a tag needs to be broken
because the optimum line break algorithm has determined the breaklocation.
