The SWI Prologue (pl package) modifies the code and modifes the old
Relase 1 (current Porter's release is
2 <http://tartarus.org/martin/PorterStemmer/c.txt>). I worry unbundling
will not be easy because upstream does not provide a library but
a simple C code (no headers, no interface) and because pl changes some
prototypes to fit better to the pl and of course adds the binding
helpers. Unified diff has 980 lines of 383 upstream lines now.
