A derived class lists the inheriting constructors of its base as its own #1358

using Base::Base; makes the constructors of Base constructors of the class that writes it, and constructors aren't inherited any further. Yet a class that derives from that class lists the using-declaration as one of its own members:

struct Base { Base(int); };
struct Mid : Base { using Base::Base; };
struct Derived : Mid {};

The page of Derived has a "Using Declarations" table with Base in it, linking to the declaration in Mid, although Derived can't be constructed from an int.

Why it happens

When it copies the members of a base into a derived class, src/mrdocs/Metadata/Finalizers/BaseMembersFinalizer.cpp skips constructors and destructors, but not a using-declaration that inherits constructors. It should skip that too. #1317 adds isInheritingConstructor to src/mrdocs/Corpus.cpp to recognize such a declaration, and it could be moved where both places can use it.

The copying predates #1317, which only makes the entry read Base instead of the name of the derived class.
