Right, but attached anyway is an update for the shared_ptr section of
the status page to make the section names and numbers match the
working paper.
This assumes my patch is going in, since I've marked everything done :-)
I'll apply this if the other patch goes in, if not I'll adjust it first.

Apart from confirming that libstdc++ only does one allocation in
make_shared none of the behaviour is implementation-defined, and even
that isn't what the standard refers to as ID, since the allocations
done by make_shared are only mentioned in a note.

I modelled the doc on your locale, ctype and messages implementation
notes, so we have a few files like this that are not really user-level
docs, but definitely worth having.  Hmm, then again, the messages and
locale docs are sort of user docs, since they describe libstdc++
extensions to the standard behaviour. My shared_ptr notes are pretty
useless to anyone except maintainers (but should allow me to close
PR24347 at least :)
