--- Comment #3 from Marshall Clow (home) <mclow.lists at gmail.com> ---
I think this is right, because of section 12.8/12:

> A copy/move constructor for class X is trivial if it is not user-provided, its  parameter-type-list is equivalent to the parameter-type-list of an implicit declaration, and if ....


The key bit there is "parameter-type-list is equivalent..."

`T(T&)` is not the same as `T(const T&)`

Please reopen the bug if you disagree.
