[O] #+headers: :tangle doesn't work

[Myles English]

Hi,

I'd just like to record a minor inconsistency in case anyone is looking
at the code and decides they can change it.  The tangle variable can't
go in the #+headers line:

#+headers: :tangle a.sh
#+begin_src sh
echo "this won't be tangled"
#+end_src

#+begin_src sh :tangle a.sh
echo "this will be tangled"
#+end_src

Thanks,

Myles
