The exit code is not zero since diff found differences, so Babel assumes the
script produced an error. Try this instead when you don't know what the
return code of the last command will be or if you know that it isn't zero
even when no error occured:
#+BEGIN_SRC sh :exports results :results output
diff testdiff.txt.orig testdiff.txt
:
#+END_SRC

I don't think so, although Babel could give a more enlightening message
about why it didn't evaluate STDOUT. It gives this on your original example:
Babel evaluation exited with code 1
Code block produced no output.

Achim.
