Concerning MATH-321, the partial fix I proposed has been withdrawn by
the complete rewrite of SVD.
This partial fix also was not considered mathematically sound by Dimitri
since the dimensions of the matrices did not match complete SVD. Well,
this was in fact desired as MATH-321 explicitly asks for non-full SVD.

So I'm not sure anymore what we need to do. If we follow Dimitri's
rationale, we should close this as WON'T FIX. If we decide to fix it, I
think we should postpone it to after 2.1 to have time to decide how we
solve it. SVD has already been vastly improved by Dimitri's work, so I
would really much like to see it published now.

Dim, what do you think about this ?
