Ok, so it stays for now. People shouldn't use spaces in their filenames
anyway, we might as well ipython as an educational tool :)

I think that the problem is that readline.py only wraps part of the full gnu
readline. If you look at the GNU readline docs:
you'll see that it's huge. Python's readline module doesn't really expose too
planck[~/test]|6> import readline
Enough for many purposes, but definitely not the whole monster.
The reason is probably the normal historical one: they wrapped as much as was
needed for the more common usage cases, and it stopped there. I'm sure one
could dig into the C wrapper and finish up the job. However, I will most
definitely NOT spend my time on that, given that the cost/benefit ratio feels
to me very much divergent.
