One other thing that I noticed while playing with the suggest module. In Suggest::transfer(), we call check before adding a word to the near_misses_final vector. This isn't the only place where late in the process we call check before storing something away. Why is that done? I would think that at that point a correction would be have an acceptable spelling.
