wrong generation of `language.dat` and friends?

[Karl Berry]

    -\addlanguage{arabic}{zerohyph.tex}{}{2}{3}
    +\addlanguage{arabic}{zerohyph.tex}{}{}{}
    ```

    I think this is incorrect, since executing `fmtutil-user --all`

Yes. I'm working on it. (The build should have stopped before pushing
out the bad data, for one thing.) --thanks, karl.
