I have them in numpy 1.4, I see them in the doceditor, but not in
http://docs.scipy.org/doc/numpy/search.html?q=chebychev&check_keywords=yes&area=default

or search for chebfit

I think they are not added to the html docs because they are not
referenced in any rst file.
That's a different issue from having them in the source and the
doceditor application.
