This is a good point. At the moment fixed_string< n >::capacity() == n. It 
would therefore make sense that this be changed so that either:

[1] fixed_string< n >::capacity() == n - 1 -- this would seem 
counter-intuitive, as fixed_string< 1 > would not be able to store any 
characters!

[2] change CharT str[ n ] to CharT str[ n + 1 ] -- i.e. add an extra 
character for the trailing null. This would make more sense, as it is 
similar to:
   char * str = new char[ s.length() + 1 ];

I personally but a vote for solution 2, but what do other people think?

Regards,
Reece
