The =cat= line below is dangerously close to a noweb reference.  The
space after test.org keeps it from being interpreted as a noweb
reference.

#+begin_src sh :tangle test.out :noweb yes
  <<task1>>
  <<b>>
  cat <<test.org >> test.out2
#+end_src

#+begin_src sh :noweb-ref task1
 echo "hello world"
#+end_src

#+BEGIN_SRC sh :noweb-ref b
 echo "b"
#+END_SRC
