When I attempt to work with shell source blocks in session mode
(:session argument) I'm receiving in RESULTS block an unwanted sign
(probably line continuation sign) in multi line commands like 'for'
loop.

-----------------------------------------------------------------------
---- How it works at the moment ---
-----------------------------------------------------------------------

#+BEGIN_SRC sh :session test
for i in `seq 1 5`;do
   echo $i
   echo 
done
#+END_SRC
 
#+RESULTS:
| > | > | > | 1 |
|   |   |   |   |
| 2 |   |   |   |
|   |   |   |   |
| 3 |   |   |   |
|   |   |   |   |
| 4 |   |   |   |
|   |   |   |   |
| 5 |   |   |   |

-----------------------------------------------------------------------
--- code evaluation taken from 'test' buffer ---
-----------------------------------------------------------------------

for i in `seq 1 5`;do
$    echo $i
> >    echo 
> done
1

2

3

4

5
 
$ echo 'org_babel_sh_eoe'
org_babel_sh_eoe
$

-----------------------------------------------------------------------
--- Expected behavior (for this case adding a sign is omitted by
running the loop in one line mode ---
-----------------------------------------------------------------------


#+BEGIN_SRC bash :session test7
  for i in $(seq 1 5);do echo "hello"; done
#+END_SRC
 
#+RESULTS:
| hello |
| hello |
| hello |
| hello |
| hello |
 


Some further troubleshooting revealed that by exporting PS2 to an empty
string this behavior can be temporarily suppressed.
