    // Call endTextEditHistory() before starting a new CompoundEdit,
    // because there's a timer that's possibly set off for 3 seconds after
    // which endTextEditHistory() is called, which means that things get
    // messed up. Hence, manually call this method so that auto-format gets
    // undone in one fell swoop if the user calls auto-formats within 3
    // seconds of typing in the last character. Then start a new compound
    // edit so that the auto-format can be undone in one go.
