    change-monitor: add trailing newline if necessary
    
    GtkSourceBuffer has a feature called implicit-trailing-newline that
    will automatically hide the trailing newline from documents. This is
    especially useful in .c or .h documents. However, it breaks the change
    monitor making it think the trailing newline has been removed.
    
    This simply adds that newline back to the document to its original form
    if that feature is enabled.
