If the strings used to display the goal are not lexable (this is believed
unlikely), this routine will generate a Diff_Failure. This routine may also
raise Diff_Failure under some "impossible" conditions.
If you want to make your call especially bulletproof, catch these
exceptions, print a user-visible message, then recall this routine with
the first argument set to None, which will skip the diff.
