 I believe that the following is the real fix for the scrolling
problem (which is a bug on all machines but a killer on sun4s):

In calculate_scrolling (scroll.c) look for this initialization code
and make the change noted:


  for (j = 1; j <= window_size; j++)
    {
      cost += next_delete_cost[j];
      matrix[j].deletecost = cost;
      matrix[j].writecost = INFINITY;
      matrix[j].insertcost = INFINITY;
      matrix[j].deletecount = j;
      matrix[j].insertcount = 0;  /* jkf fix, was j */
    }


This is from version 18.37 and may look different in other versions.
