couple problems

If you load 0.9.23 from the public repository into a new image, the tests don't run. The various structure #initialize class methods have been removed, so the class instance variables aren't initialized. Instead of adding the methods back, could the code be changed so that these variables are lazily initialized? Also, the VisitorRendererWiki>>emitCrWithoutDuplicates assumes that #cr method on stream emits only a Character cr. However, the ANSI standard says that #cr emits "a sequence of character objects that constitute the implementation-defined end-of-line sequence" so you can't assume that Character cr will be put on the stream. Instead of getting the contents, I would suggest adding an instance variable that says whether the last thing put on the stream was a #cr from #emitCr. John Brant
