[tug-summer-of-code] [tug-board] Better Unicode compliance -- XeTeX and LuaTeX are not versions of TeX

         http://tug.org/gsoc/ideas.html
    says that it "would give rise to a much more fully Unicode-compliant 
    version of TeX".

I agree "extension" is better than "version" here.  I changed it.
