Review comment (suggestion):
```suggestion
    let document_directory = doc
```

Code after:

    // Make sure there's room at the end of the document if the last
    // selection butts up against it.
    let end = text.len_chars();
    let last_range = doc
        .selection(view.id)
        .iter()
        .last()
        .expect("selection should always have at least one range");
    if !last_range.is_empty() && last_range.to() == end {
        let transaction = Transaction::change(
            doc.text(),
            [(end, end, Some(doc.line_ending.as_str().into()))].into_iter(),
        );
