The "from" is the original code, the "to" is my modification to show 
that omitting the \001/\002 constructs will make IPython not show the 
colour escape codes. Of course this wasn't meant as a solution because 
the escapes are there for a reason (as you correctly pointed out). 
Simply removing them will just introduce a new kind of problem.
