When you import the module rlcompleter in a python script in Centos 6 (x86_64), the control sequence \033[?1034h is printed in stdout. The problem is that these sequence is not visible by the user and cause a lot of confusion. 

In my case I compared the output of a python script (the integer 6) in bash and I got:

 test: 6: integer expression expected

How to reproduce:

 BASH SCRIPT that calls
 echo $id|sed -n l
 if test ${id} -eq 0;then

 import rlcompleter
 print a

[valva@wn009 ~]$ bash 
\033[?1034h2$ line 3: test: 2: integer expression expected

This only has happened to me in Centos 6 (python 2.6.5) I've tested in Centos 5, debian and Ubuntu and it does not happen.

Can you give a simpler script (maybe in Python :) to reproduce this?  Also, 2.6 only gets security fixes now, so please use 2.7, 3.2 or 3.3.
