Well, if you had mentioned that in the documentation, you wouldn't
have had to write a patch ;-P .

Works like a charm in Cygwin rxvt (using readline) and Windows IPython
By the way (introducing a new bug(?): if I run Cygwin IPython (meaning
"Linux" Python and GNU readline) the output prompt shows the colour
escape sequences as coloured faces. This only happens with the
standard Windows console and the well-known "Console".
The paradox thing is that prompt_in1 and prompt_in2 display fine -
it's just prompt_out that has this mistake. Is there some special code
in IPython that constructs the in prompts differently than the out
