/* The five-operation with reference edge *ref has just been performed.
   Make a list in good_or[0..*ngood_or-1] of the reference edges of
   legal five-reductions (oriented editions) that might be canonical,
   with the first *ngood_ref of those being ref.
   Make a list in good_mir[0..*ngood_mir-1] of the
   reference edges of legal five-reductions (mirror-image editions)
   that might be canonical, with the first *ngood_mir_ref of those being
   ref.
   *ngood_ref and *ngood_mir_ref might each be 0 or 1.  If they are
   both 0, nothing else need be correct.
   All the edges in good_or[] and good_mir[] must start with the same
   vertex degree and end with the same vertex degree (actually, colour
   as passed to canon_edge_oriented).
