    Arithmetic: short version of new options in book and comments
    
    In the previous commit, we added the two new `--wcshdu' and `--wcsfile'
    options to Arithmetic, but in the manual, I forgot to add their short
    formats. I had also forgot to remove their letters from the list of
    available short option letter list. Both are corrected with this commit.
