The rule of thumb is that Org should support the current major version
of emacs and one previous.  These functions have been aliased for a
while, with fancy-diary-display marked as deprecated.  The commit that
removed them from emacs
<http://bzr.savannah.gnu.org/lh/emacs/trunk/revision/118057> says this
is at least since v 23.1, so it’s safe to just use the new name
unconditionally.

> +      (diary-display-hook '(diary-display-function))

This puts the symbol ‘diary-display-function’ in the list, which may
or may not be correct (it’s different than the old behavior, which
effectively put the value of that variable).  Maybe you want ‘(list
diary-display-function)’ instead?
