Hoss Man commented on LUCENE-915:
---------------------------------

can you elaborate on why you think this is a bug?  

This is a fairly basic function of the Porter Stemming Algorithm, and exists in the official java version of the algorith published by Martin Porter...

(you may not arge with Porter's decision to strip trailing Es, but it's in the algorithm, and the class implements the algorithm)
