NFD Insertion Bixnum creation
In nfd.cpp, in creating the NFD Insertion BixNumCCs, two unicode sets are pushed to the BixNumCCs variable every iteration of the loop: i.e., for each character detected as being a target for the NFD transform. Despite this, only the first two unicode sets are ever accessed. I believe the two sets being pushed were accidentally included in the scope of the for loop, instead of just before it, so I moved them outside the loop.
