Hi,

in the following org file the second block gets not exported (tested with
text and html exporter, release_8.0.2-119-g646f1a):

--8<---------------cut here---------------start------------->8---
#+OPTIONS: toc:nil author:nil

#+BEGIN_SRC sh :exports results :results output
cat testdiff.txt.orig
#+END_SRC

#+BEGIN_SRC sh :exports results :results output
diff testdiff.txt.orig testdiff.txt
#+END_SRC

#+BEGIN_SRC sh :exports results :results output
diff testdiff.txt.orig testdiff.txt | cat
#+END_SRC

#+BEGIN_SRC sh :exports results :results output
ls testdiff.*
#+END_SRC
--8<---------------cut here---------------end--------------->8---

Why is the `diff' command alone not exported while the piped `diff' via
`cat' works?  Is this this a bug?
