Yes, it works great on the following example (which includes "direct
printing", in the sense of echoing the #+BEGIN_SRC lines) as well as in
the ":wrap" case.

--8<---------------cut here---------------start------------->8---
#+name: fetchcoq
#+BEGIN_SRC sh :exports none :results raw :var f="foo.v"
echo "#+BEGIN_SRC coq"
head $f
echo
echo "#+END_SRC"
#+END_SRC

Test using direct printing

#+name: test1
#+call: fetchcoq(f="demo.v") :results raw

#+results: test1
#+BEGIN_SRC coq
Definition toto : forall x, exists y, x = y.

Lemma foo: forall x, x=x.
#+END_SRC

#+name: fetchcoq2
#+BEGIN_SRC sh :exports none :results raw :var f="foo.v"
head $f
echo
#+END_SRC

Test using wrap

#+name: test2
#+call: fetchcoq2(f="demo.v") :wrap src coq

#+results: test2
#+BEGIN_src coq test
Definition toto : forall x, exists y, x = y.

Lemma foo: forall x, x=x.
#+END_src
--8<---------------cut here---------------end--------------->8---

Thanks,

Alan
