Docs for optional::operator= with inplacefactory missing

[Yechezkel Mett <ymett.on.boost@…>]

The documentation doesn't seem to mention that optional::operator= can take an InPlaceFactory. The only assignment operators mentioned are

optional& optional<T>::operator= ( T const& rhs ) ;
optional& optional<T>::operator= ( optional const& rhs ) ; 
template<U> optional& optional<T>::operator= ( optional<U> const& rhs ) ;

(and the equivalents for T&) none of which can take an InPlaceFactory. Presumably there should be something equivalent to the

template<InPlaceFactory> explicit optional<T>::optional( InPlaceFactory const& f ); 
template<TypedInPlaceFactory> explicit optional<T>::optional( TypedInPlaceFactory const& f );

constructors.

I presume that you're referring to the Detailed Semantics page, as these operators to show up in the Synopsis.

(In [71048]) Add assignment operators taking an InPlaceFactory to the Detailed Semantics section. Fixes #5378.
