After introducing the support of cuneiform the output of --list-languages and some fragments of the man page became in my opinion slightly misleading.
It is intentional that --list-languages doesn't show which OCR engine is currently selected. However, I made the documentation a bit clearer: http://jwilk.net/hg/djvu/ocrodjvu/rev/6f490681bcc9
If such clarification is satisfactory for you, I'll close this bug by the next upload. Otherwise, I'll have tag it +wontfix.
