Well, it's not the fault of Apple's Pythons.  If the problem is the 
echo, you can see exactly the same results by using a current python.org 
64-/32-bit Python.  Those Pythons, like the Apple-supplied system 
Pythons, are linked with BSD editline.  If, instead, you install the 
corresponding python.org 32-bit-only Python, the echo remains turned 
off.  As I mentioned before, the 32-bit-only Python is linked with GNU 
readline.  That's the only difference I can think of that makes sense. 
(I see the same results with both OS X 10.6 and 10.7, BTW.)

So, if there is a problem, the likely culprit is libedit, the editline 
library.   Another clue: try using another Apple-supplied utility that 
is linked with libedit, for example, dscl.  Same thing happens there: 
echo is immediately re-enabled.
