Why is Babel-C trimming its output?

[Michaël Cadilhac]

Hello,

Quick question here: in ob-C.el, before returning the output of a C
file, there's this line:

(setq results (org-trim (org-remove-indentation results)))

That seems quite arbitrary; is it on purpose?  I have a C file that
outputs some sort of list of formatted numbers, e.g.:

  0  -17.8
 40    4.4
 80   26.7
120   48.9

and only the first line gets trimmed, leading to a faulty output.

This does not seem to be a universal thing in Babel; for instance:

#+begin_src emacs-lisp :exports both :results value raw
  " 0\n 1\n2\n"
#+end_src

…results in:

#+RESULTS:
 0
 1
2

But the same thing in C:

#+begin_src C :exports both :results output raw
  printf (" 0\n 1\n2\n");
#+end_src

…results in:
#+RESULTS:
0
 1
2

Cheers,
M.
