All the more reason to stick with the existing htfuzzy framework, so that
stemming can be turned on/off at search time.  The actual stemming technique
can be applied either way - whether it's done at indexing time (within
htdig) or just after indexing by htfuzzy.  The framework used by algorithms
like soundex, metaphone and accents could be applied equally well to the
stemming algorithms, so I'd recommend studying these algorithms to figure
out how to add the new stemming code to the mix.
