Perhaps this change should be documented in the `Incompatible
Lisp Changes in Emacs 22.1' in etc/NEWS.  When users have hooks
that modify the contents of the *Occur* buffer then these hooks
will fail after the read-only flag was set on the *Occur* buffer.

A similar change made in compile.el a half year ago (that sets the
read-only flag before running `compilation-mode-hook') could be
mentioned in the same section of etc/NEWS too.
