Every Document Operation is always an edit operation. Insertion of characters, deletion of some text or the creation of a new blip are all edit operations on a document. That is why in the createAppendBlipDelta(), besides sending the operation newBlipOp that creates the blip with the given text, the client also sends an empty DocOp so the server and other clients can detect this isn't just an edit operation but it is the creation of a new blip.
That being said, to detect it is an edit you just don't send the empty DocOp. You might also want to look at the createTextInsertion function. It creates a DocOp that inserts a given text at a given index.
