[Babel] [possible bug] Empty src block prevents other block to expand

[Nicolas Girard <girard.nicolas@gmail.com>]

The empty src block at the beginning of the following file prevents
"capture-tmpl" to expand when tangling.

Admittedly, this empty src block shouldn't exist in the first place,
it's just a residue of some former confg of mine that didn't cause any
problem until I upgraded Org to the latest ELPA package
(8.2.7a-elpaplus -- 20140619).

The test file is
---8<-------
* Empty org block
#+begin_src org :noweb yes
#+end_src
* Other blocks
#+name: capture-tmpl
#+begin_src org :results value
  ,* A
  :PROPERTIES:
  :ID: %(org-id-new)
  :END:
#+end_src

#+name: capture
#+begin_src emacs-lisp :tangle no
  ("C" "Capture" entry "
  <<capture-tmpl>>")
#+end_src

#+begin_src emacs-lisp :noweb yes
  (add-to-list 'org-capture-templates '
  <<capture>> 'append)
#+end_src
---8<-------

And the Makefile I used is simply
---8<-------
all: conf.el

%.el: %.org
    emacs --batch -Q -l ob-tangle -l ob-org \
    --eval '(setq org-babel-use-quick-and-dirty-noweb-expansion t)' \
--eval '(setq org-confirm-babel-evaluate nil)' \
--eval '(org-babel-tangle-file "$<" "$@" "emacs-lisp")'
---8<-------


Cheers,
