I was looking at the documentation and the Serialization and "Differences
std::vector<T>" pages were both empty. It would be nice to indicate there's
nothing there yet for those pages.

On the Semantics page is says:

auto_buffer( const auto_buffer& r );

   - *Effect:* Copy constructor.
   - *Postconditions:* capacity() == max(r.size(),N) && size() == r.size() .

   - *Throws:* Nothing if size() <= N and the copy constructor of T cannot
   throw. Otherwise this might throw exceptions from the allocator of from T's
   copy constructor.

I think there's a typo in the last sentence there.
