I think emacs-w3m hits the same problem. Overlays from 1 to 1 in
otherwise empty buffers span 1 to (point-max) after insertion of text;
previously (before the change you mention, I think) such overlays
still spanned 1 to 1 after insertion of text. See:

          <URL:http://emacs-w3m.namazu.org/ml/msg06543.html>

One such overlay has these properties:
