Serialize buffer in terms of operations rather than state

Browse source 
This is required because, after joining, we want to be able to refer
to operations that have happened prior to joining, which are not
captured by the state. There is probably a way of reconstructing operations
from the state, but that seems unnecessary and we've already talked about
wanting to have the server store operations rather than state once we start
persisting worktrees.
