f5f46b1fed Separate document history into Cell 
As history is used separately from the rest of the edits, separating it
can avoid needless borrowing and cloning. But one need to be aware later.

9821c4dd3b Optimize Changeset::is_empty() 
Checked the ASM output for these three options:

pub enum Operation {
    /// Move cursor by n characters.
    Retain(usize),
    /// Delete n characters.
    Delete(usize),
    /// Insert text at position.
    Insert(String),
}

pub struct A {
    changes: Vec<Operation>,
    len: usize,
}

impl A {
    pub fn is_empty1(&self) -> bool {
        match self.changes.as_slice() {
            [] => true,
            [Operation::Retain(_)] => true,
            _ => false,
        }
    }

    /// `true` when the set is empty.
    pub fn is_empty2(&self) -> bool {
        let len = self.changes.len();
        len == 0
        || (
            len == 1
            && self.changes[0] == Operation::Retain(self.len)
        )

    }

    pub fn is_empty3(&self) -> bool {
        match self.changes.as_slice() {
            [] | [Operation::Retain(_)] => true,
            _ => false
        }
    }

}

b0b5451c38 Since insert preceedes deletes, follow that ordering in Transaction::changes. 
Produces the same output but will take the happy path.
