I think this means that if the string contains a charT*, it will never
be null (but rather point to a special empty string object). I don't
see why the user would need to know that, unless it implies something
special about begin() and end().

Without looking at the code, I would expect that the const_string<>
would share a representation with str, thus implying that it had
better not outlive str.
