Emacs 24 doesn't seem to have add-function; copying nadvice.el into my
site-lisp directory seems to take me down the gv-ref rabbit hole (in
the sense that I tried installing it into Emacs 24 before and found I
was just copying more and more stuff from master). Do you have an
old-fashioned alternative? (Sorry, I only tried advice for the first
time, while trying to do the above hack more neatly.)
