 This is a "follow-up" bug report as advised by Fernando Perez in the
 thread
 http://thread.gmane.org/gmane.comp.python.ipython.user/2361/focus=2377

 Cygwin IPython (meaning Python and GNU readline under Cygwin) shows the
 colour escape sequences as coloured faces in the output prompt. This
 happens in all Windows consoles.

 The paradox thing is that prompt_in1 and prompt_in2 display fine - it's
 just prompt_out that has this mistake.

 This is what I already found out:
 Removing the \001/\002 from "class InputTermColors" in ColorANSI.py solves
 the mistake (of course now readline doesn't wrap lines anymore so this is
 not the solution - just a hint where the problem lies)

 This raises another interesting question: if the error lies in the class
 InputTermColors why do the input prompts display fine but the output
 prompt is garbled?! I guess if we solve this problem then we have the
 solution for the problem.

 I have discussed this problem in the Cygwin mailing list (because there
 were two other applications that had the same problem and I wondered
 whether readline is at fault)

 The thread is at

 Eric (the Cygwin readline maintainer) answered an pointed out the bugs in
 those two apps

 Eric's answer is at

 He couldn't correct the Python code but he guessed

 "In other words, I wonder if IPython is adding extra \1
 somewhere else in the sequence of things, which is then resulting in
 the spurious \1 to the cmd terminal."
