Parcing the French in the Bibliography (badly, I might add - my last French class was over ten years ago and I haven't been keeping up) it appears that you may be correct. Although it is hard to tell because the page in question seems to list all the extant versions of the text (original through all copies), so I am not sure what they are conveying exactly.

*makes annoyed face*

Damnit. I need to get back to reading French.
