Hi Seb,

My first idea was to use the ":results list" header argument, to return
a simple list (rather than a table in which the last element has two
columns)

#+begin_src sh :results list
  echo "eric schulte"
  echo "dan davison"
  echo "seb vauban"
#+end_src

#+results:
- ("eric" "schulte")
- ("dan" "davison")
- ("seb" "vauban")

But that didn't work out quite as well as expected.  Perhaps list
results should be made "smarter" by concatenating list elements that
happen to be lists themselves into strings...

I then tried the following, which should work, enabling you to split the
raw results on newline in subsequent code blocks.  Note this approach
will also preserve things like ";"'s which may have been eaten by org
table import.

#+begin_src sh :results scalar
  echo "eric schulte"
  echo "dan davison"
  echo "seb vauban"
#+end_src

#+results:
: eric schulte
: dan davison
: seb vauban

Hope this helps -- Eric
