[Pythonmac-SIG] readline space problem?

In ipython, which uses readline for tab completion in the shell, on my
powerbook when I do

  >>>cd pyth<TAB>

The completer generates

  >>>cd python _

where the _ is a placeholder for where the cursor ends up.  When
completing on a long path, this is annoying, because I have to
backspace out all those extras spaces.

I brought this up on the ipython list and Fernando Perez and I spent
some time trying to hunt it down.  In the end, he was firmly convinced
that this was a platform specific readline problem.  I get this
behavior in both the X11 xterm and the OS X Terminal.

I'm have readline-2.3-binary and readline-2.3.source listed in my
Python Install Manager.

Someone on the ipython list suggested

    Fink's python and underlying readline do the right thing.

    There is also something (I can't remember what) to turn on os x's
    shipping readline to do the right thing. Search google. There is one
    rather difficult solution - rebuilding readline - and another which is
    just to change some configuration if I remember correctly.

Does this ring a bell with anyone?  Any ideas on how to fix this
little annoyance?
