[go-nuts] Proper way to construct|format this code...

[edb9818]

What is the standard way to construct|format the following code snippet?  I 
think the first is more readable; however, is there any accepted syntax I 
should be using working my way up the ladder as a senior developer?

block, err := aes.NewCipher(key)
if err != nil {
 return err, nil, nil
}

nonce = make([]byte, 12)
if _, err := io.ReadFull(rand.Reader, nonce); err != nil {
 return err, nil, nil
}

aesgcm, err := cipher.NewGCM(block)
if err != nil {
 return err, nil, nil
}

return nil, nonce, aesgcm.Seal(nil, nonce, plainText, nil)


or

block, err := aes.NewCipher(key)
if err != nil {
 return err, nil, nil
} else {
 nonce = make([]byte, 12)
 if _, err := io.ReadFull(rand.Reader, nonce); err != nil {
  return err, nil, nil
 } else {
  aesgcm, err := cipher.NewGCM(block)
  if err != nil {
   return err, nil, nil
  } else {
   return nil, nonce, aesgcm.Seal(nil, nonce, plainText, nil)
  }
 }
}
