SPOOLing in sql developer does not take into consideration SET ECHO OFF

Question

I'm running SQL Developer 3.1.07.42 on Windows 7 64 bit with java 1.7
I have the following very simple script just to show the problem:
SET ECHO OFF;
SET FEEDBACK OFF;
SET SERVEROUTPUT ON;
SET VERIFY OFF;
SET PAGES 0;
SET HEAD OFF;
SPOOL c:\test.sql
SELECT 1, 2, 3 FROM DUAL;
SPOOL OFF;
/if I run it in TOAD 10.6.0.42 it creates the file with
         1          2          3This is as expected (by me)
if I run the exact same query in SQL Developer 3.1.07.42 , it creates the file with:
< SELECT 1, 2, 3 FROM DUAL
1 2 3(the < above is actually ">" but the CODE formatting software is screwing ">")
but I don't want the ECHOed command to be spooled. For the life of me, I cannot find a way to disable the ECHO from spooling in sql developer.
Tried the same in 3.0.4 and 2.1.1 with the same (bad) result (plus some warning on some of the unsupported SET commands).
Am I missing something obvious? Cause like this, the spool command cannot be used in sql developer to generate a CSV file for example, because of the echoed command. And windows doesn't come with SED by default so that is out. (plus that my original script is integrated into a much larger and complex set of scripts and the main script using them is executed from SQL Developer as a company policy (so that everybody uses the same tool and the code runs the same for everybody))
Any ideas/suggestions are welcome
Thanks.

Hi Gary, you seem to have some extensive knowledge. I'd like to follow-up on this thread and try to understand why SQL Developer won't hide the code even though I'm already running the code as a Worksheet (I assume you mean Run Script F5 button in SQL Developer).
I generally develop in SQL Developer that does a lot of dbms_output to echo data using a Spool command. When I'm in SQL Developer I can't get the code NOT to spool, it typically is echoed directly in the spool file at the top followed by the dbms_output data. If I save the sql file and run in in sqlplus it only outputs the data (good). If I use @C:\xyz_script.sql and hit F5 in SQL Developer it only outputs the data (per your previous answer) -- good.
So why can't I hit F5 in SQL Developer in the script file and have it only output the data? It just doesn't work no matter how many "SETs" you turn-off.
Looks like Echo, Term, Feed are supported in SQL Developer, maybe supported means something other than work.
