In htmlfontify.el (htmlfontify-buffer), hfy-force-fontification calls
either font-lock-fontify-region (in interactive mode) or
font-lock-fontify-buffer (in non-interactive mode).

The latter funcion in turn calls font-lock-fontify-buffer-function which
apparently points to jit-lock-refontify.

I hope either the htmlfontify-buffer DTRT or it may fail to re-fontify
under certain circumstances.
