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 (buffer, FALSE). When the buffer is modified,
it will automatically toggled on the modified bit again. When the modified
bit flips, the buffer emits a "modified-changed" signal.
