I.e. don't detach in the replace() overloads that delegate to replace_helper() if this string is shared, instead create a new string and copy characters from this string to it, along with the "after" string, then swap it with this. Do the same thing if "before" is shorter than "after" and there isn't enough capacity to do the replacement without reallocating. Use std::copy* and std::move*, which will both fallback to memmove/memcpy, but they have C++ API, which is more readable.
