Thanks for the tip but... that may be a bit drastic, I mean forcing every
snippet of *every language* to behave like that: I'm convinced it's the most
natural choice for sh blocks, but maybe the less natural (i.e., must be
overridden) for all other programming languages.

In fact, I have the strong impression that we should need this on a language
basis, something like:

#+begin_src emacs-lisp
  (add-to-list 'org-babel-default-header-args '(
               (sh . (:results . "output"))
               (emacs-lisp . (:results . "value"))))
#+end_src

I feel the same about the Babel "file" property:

#+BABEL: :engine mysql :cmdline -S server -U sa -P secret -d storeall -n -w 700 
-s " "

Not being able to specify the language these defaults apply to may rapidly
lead to clashes... Or we have to set the default for the language for which we
have the biggest number of chunks, and explicitly set the values for all the
other snippets that are written in other languages.

Maybe allowing such a specification line?

#+BABEL sql: :engine mysql :cmdline -S server -U sa -P secret -d storeall -n -w 
700 -s " "

Best regards,
  Seb
