Add a comment how strings of length 0 are treated and
that they always will result in the return of a string
equal to the constant string "".
The previous implementation would return a string header that uses
runtime.zerobase as the backing array pointer while the string constant
"" has 0 as pointer value.
Using 0 has the backing array pointer is also the behaviour of
string([]byte(input)) which makes the new behaviour a better drop in
replacement.
