Used to keep track of whether the buffer has been modified since the last time it was saved.
Whenever the buffer is saved to disk, call `gtk_text_buffer_set_modified (this, FALSE)`. When the
buffer is modified, it will automatically toggle on the modified bit again. When the modified bit flips, the buffer emits the [
signal@Gtk.TextBuffer:GtkTextBuffer:modified-changed
] signal.
