First, NSString’s prefix function returns false for empty string parameters, and this would be a significant departure in behaviour. Second, while an empty string is technically a prefix to any other string, that is hardly ever an interesting answer; it is a trivial solution, just as y=0 is for y(x)=y’(x). It is easy to special-case if one really needs to consider the empty string.
