LGTM after removing the unneeded constraint.

----------------
Interestingly this one does not seem to be constrained. http://eel.is/c++draft/string.streams#istringstream.cons-6

The same in the paper. I can't find a reason in the WG21 review either. I assume it's a bug in the Standard. For now let's remove this one and maybe we should file an LWG issue to remove them from the constructors when not needed.
