So What. If someone want a null terminated string use c_str() or first call
ensure_null_end(). That is the way I designed it and that is the way
Aspell uses it.

The std::string class (NOT the Microsoft string class) does NOT guarantee
that the string is always null terminated. In fact it doesn't even
guarantee that the string will be stored in a continuous area of memory.
The only thing it guarantees is that that the c_str() method will return a
pointer to a null terminated string. The string returned is invalided when
any non-const member function is called.
The acommon::String class is modeled after the std::string class expect
that it guarantees that the string will be stored is a continuous area of
memory.
