results are correct with an error 2.e-16. My question is whether we should
change it to 2.2.... e-16, while we could take as an example a point (1,1)
where 1.000000... would be a better illustration of the computations.

good idea! But I was confused since the test which fails does not appear
to exist on my 4.6.alpha1.
Sorry, I am being completely stupid -- of course the failing test is in
the patch and I was looking at unpatched files! But now I find that the
patch does not apply to 4.6.alpha1 so I will have to rebase it. When I do
that I will try to use better examples.
