* * `lines`: the lines in the document that are changing
* * `"insertText"` (emitted by [[Document.insertNewLine]])
* * `range`: the [[Range]] of the change within the document
* * `text`: the text that's being added
* * `"removeLines"` (emitted by [[Document.insertLines]])
* * `range`: the [[Range]] of the change within the document
* * `lines`: the lines in the document that were removed
* * `nl`: the new line character (as defined by [[Document.getNewLineCharacter]])
* * `"removeText"` (emitted by [[Document.removeInLine]] and [[Document.removeNewLine]])
