As you adviced, I can play with the optional parameter in ob-ledger's code.

But what about the results of sh code?

Imagine now that I'm forced to use =sh= instead of =ledger=, in the following
pratical case:

#+srcname: reg
#+begin_src sh
m4 scorpios-ledger.dat | ledger -f - reg unknown
#+end_src

I'm using =m4= (and thus make some pre-processing) because I need (or want) to
be able to switch between =ledger= and =hledger= and comment in or out the
directives that are accepted by one but not by the other.

Then, such a result is still problematic:

--8<---------------cut here---------------end--------------->8---

I've looked in =org-babel-execute:sh= and =org-babel-reassemble-table=, among
others, to look for similar constructs (calls to =org-table-convert-region=)
but did not find any.

Is there still a solution to get such results?

Couldn't we specify somehow the field separator as an extra header argument?
I've looked for such an already existing in
http://orgmode.org/manual/Specific-header-arguments.html#Specific-header-arguments,
but that does not seem to be available yet. Though, I do not know if this is
the right solution. I'm sure you'll tell me... ;-)

Best regards,
