I can confirm it works, too, for the 1 2 3 example.  However, it puts double 
quotes around text:

#+BEGIN_SRC sh :results list
echo hello
echo world
echo !
#+END_SRC

#+RESULTS:
- "hello"
- "world"
- "!"

I was working on other ob-shell related stuff and my Emacs got into a mixed 
state where =ob-shell/results-list= was defined, but the fix wasn't (or wasn't 
loaded).  I fixed the failing test before I saw this thread and Ihor's fix.  
The way I solved it was to wrap either =org-babel-import-elisp-from-file= or 
=org-babel-sh-evaluate= like,

(mapcar #'car (org-babel-import-elisp-from-file tmp-file))

or 

(mapcar #'car  (org-babel-sh-evaluate session full-body params stdin cmdline))

Doing this (without Ihor's fix in place) returns:

#+BEGIN_SRC sh :results list
echo "hello"
echo "world"
echo "!"
#+END_SRC

#+RESULTS:
- hello
- world
- !

The underlying issue, so far as I understand it, is that 
=org-babel-import-elisp-from-file= returns a list-of-lists.  For example, ((1) 
(2) (3)) or (("hello") ("world") ("!")).  I thought it appropriate to flatten 
it out to (1 2 3) or ("hello" "world" "!").

Independently from how I addressed the bug, I feel it raises an important 
question: how should :results list handle text/strings? 

I'm not sure which approach is more "appropriate".   If I echo a string without 
quotes, as I did in the first example, should it return a list that's got 
quotes?  The hello world example is a little contrived–it's good practice to 
use double-quotes.  I think a more realistic use case would be listing a 
directory.  In that case, I'd probably want the list of items to be unquoted:

Original:

#+BEGIN_SRC sh :results list
ls /home/ahab/.emacs.d/straight/repos/org/testing/lisp/ | head -n 3
#+END_SRC

#+RESULTS:
- ("test-ob-awk.el")
- ("test-ob-C.el")
- ("test-ob-clojure.el")

Ihor solution:

#+BEGIN_SRC sh :results list
ls /home/ahab/.emacs.d/straight/repos/org/testing/lisp/ | head -n 3
#+END_SRC

#+RESULTS:
- "test-ob-awk.el"
- "test-ob-C.el"
- "test-ob-clojure.el"

MAPCAR solution:

#+BEGIN_SRC sh :results list
ls /home/ahab/.emacs.d/straight/repos/org/testing/lisp/ | head -n 3
#+END_SRC

#+RESULTS:
- test-ob-awk.el
- test-ob-C.el
- test-ob-clojure.el

For :results list, the manual says, "Interpret the results as an Org list.  If 
the result is a single value, create a list of one element".  I don't find that 
clarifies what would be best.

Thoughts?
