many thanks for the details.  I'd actually recently seen the problem
on a colleague's new MacBook.  The bug can be easily produced in a
plain python shell (no ipython) by loading and configuring readline a
little.  I hope the official MacPython team fixes things soon, as this
can be annoying and time-consuming to fix, and it kind of makes
ipython useless on OSX.
