* English word stemmer

This library stems an English word, based on the algorithm
described in the paper "An algorithm for suffix stripping
(M.F.Porter)".

Function `stem-english (str)' returns a list of possible stems in
order of string length.

This is a re-written version of `stem.el' originally written by
Tsuchiya Masatoshi, to be compatible with modern Emacs, removing
all compiler warnings by explicitly defining lexicographically
bounded variables.
