TC == "technical correction", I believe.

Right, when it was pointed out all the standards committee people realized
it was an accident; it was intended all along to be a requirement that
the elements of vector are contiguous, which means that &v[0] or &*v.begin()
can be passed to a C routine that wants a T* that points to v.size()
consecutive elements.
