Yes, that too.

So, to summarize, Wolfgang and I found three issues in the
specification of the fold -xxx functions:

      1. The Error Conditions paragraph for fold-left conflicts with
the signature of the function.

      2. The Error Conditions paragraph for fold-right conflicts with
the signature of the function.

      3. The Rules section (code) for fold-right conflicts the
signature of the function.
