Right now you get to go and remove the print from bessel-k in
src/bessel.lisp. :-(
Rather than doing these fixes one at a time, perhaps it's time to consider
what maxima should do with these kinds of errors and fix them all at once.
I certainly don't want the message to be removed; there needs to be some
way to inform the user about issues. This is what needs to be designed.
