The description of kn_encode_base64() in keynote(3) is inaccurate: Since the function is a simple wrapper around b64_ntop(), there is no restriction on the possible lengths of the raw data in `src'. This is likely a confusion with kn_decode_base64(), where there is such a restriction on the `src' string, but only after removal of whitespace. Since the length of `src' is not part of the function call, this doesn't seem to be worth mentioning.
