Hi Nicolas,
for exporting a buffer w/o buffer-file, sometimes ago you added property
:input-buffer to the communication channel (on my feature request), so
this used to work (one of the two vars was always non-nil):
#+BEGIN_SRC emacs-lisp
(let ((input-file (plist-get info :input-file))
(input-buffer (plist-get info :input-buffer))) ...)
#+END_SRC
But now the :input-buffer property seems to have disappeared from the
'info' plist again. If so, its a real pity, since crucial info is missing
whenever 'buffer-file-name' is nil.
