"Loss of data" means "you don't get back exactly what you started with". 
Taking your example, I believe that you want both "A\nB\nC" and 
"A\nB\nC\n" to result in lines ["A","B","C"], so this operation is not 
reversible.

Or did you want "A\nB\nC\n" to result in ["A","B","C",""] ?  That would 
surprise me more. Most inputs have terminating newlines on the final 
line.
