bug#24270: Seeming bug in `setf'

[Rafael D Sorkin]

Hello,

The macro `setf' seems to have developed a bug somewhere between emacs 23.1.1 
and 24.3.1:


(emacs-version) ; GNU Emacs 24.3.1 (x86_64-pc-linux-gnu, GTK+ Version 3.10.7) 
of 2014-03-07 on lamiak, modified by Debian

(setq z ())
(getf z  'indic)                        ; nil
(setf (getf z 'indic) 6)                ; (indic 6)  SHOULD BE JUST 6
(getf z  'indic)                        ; 6  okay
