I will let others debate and decide that.

That's a bug. I had tried to take care of that in the patch, but I missed some
parts. Please try the attached patch, which should fix it.

I also fixed an infinite recursion bug that occurred sometimes, due to
Info-goto-node calling Info-fontify-node and (from the patch) vice versa.

The change log remains the same.
