Comment 10 for bug 108834

FYI, after running into this myself I encountered following:

Personally, I just went ahead and edited:

         return string[0,place] + "\n" + wrap(string[place+1..-1], width)
       end

Seems to me a reasonable solution, but of course, depends on how the formatter is used I guess.
