Bug: babel: results switch (output vs. value) has no or wrong effect for sh source block [7.7 (release_7.7.107.g7a82)]

[Andras Major <andras.g.major@gmail.com>]

Hello, here is an example of apparently erroneous behaviour of the
:results switch.  In this example, we use an sh block, but it also
appears to affect other languages (will need more investigation).

Example Org code:

#+begin_src sh :exports output
  echo "Hello World 1"
#+end_src

#+results:
: Hello World 1

#+begin_src sh :exports value
  echo "Hello World 2"
#+end_src

#+results:
: Hello World 2

Am I missing something here or should the second instance really
output something like an integer exit value from echo?

Cheers,

  András
