 // This is mpcomplete's pattern for saving a string copy when dealing with
 // a function that writes results into a wchar_t[] and wanting the result to
 // end up in a std::wstring.  It ensures that the std::wstring's internal
 // buffer has enough room to store the characters to be written into it, and
 // sets its .length() attribute to the right value.
 //
 // The reserve() call allocates the memory required to hold the string
 // plus a terminating null.  This is done because resize() isn't
 // guaranteed to reserve space for the null.  The resize() call is
 // simply the only way to change the string's 'length' member.
 //
 // XXX-performance: the call to wide.resize() takes linear time, since it fills
 // the string's buffer with nulls.  I call it to change the length of the
 // string (needed because writing directly to the buffer doesn't do this).
 // Perhaps there's a constant-time way to change the string's length.
