Re: French stemmer test data wrong?

Ah, thanks for the clarification! I didn't realize the replacements were 
designed to happen letter-by-letter, left-to-right. That means it's 
basically fortuitous that all the tests pass for my process, but having 
got it working I think I might leave it alone. Have to do the equivalent 
JS version now. :-)

Cheers,
Martin
