review of previous bug fix

Generally speaking the algorithm now works correctly and produces the
right shape of forest for the test ambiguous grammar as well.  It does
not correctly perform the "reductions".  It seems that I deliberately
disabled this part of the functionalities in a previous debugging
tour.

So I have to enable it again and see if it works.
