It should be very close.

Another annoying difference between Emacs and XEmacs.  Diary-mode is
what adds (diary-redraw-calendar) to after-save-hook.  It's being
added with the "local" option set to t.  In Emacs, this causes the the
hook to become buffer local.  In XEmacs, this option only has an
effect if the hook is already buffer-local.  Otherwise, it's added to
the global hook.  I've added a call to make-hook-local to correct
this.
