N4529 [propagate_const.assignment] depicts the two operator=s described as returning by value. This is obviously incorrect. The class synopsis correctly shows them as returning by reference.

Move to Tentatively Ready.

Proposed resolution:

This wording is relative to N4529.

1. Edit [propagate_const.assignment] as indicated:

   -1- template <class U>
   constexpr propagate_const& operator=(propagate_const<U>&& pu)
   

   […]

   -5- template <class U>
   constexpr propagate_const& operator=(U&& u)
