The function that allows you to specify the capacity is spelled
fixed_string<N> result = s1 + s2;
This is not particularly efficient on paper, it's one extra memcpy, but
that's unavoidable when using op+.
And, while I agree that op+ giving 1024 for two 512 inputs isn't very
useful, op+ for inputs 12 and 8 giving 20 seems not that useless.
