Edward,
Thanks for the information. Do you know of a way to get IPython to use
edline instead? IPython is growing in popularity for Python programmers,
and it seems like getting a way forward that works with edline makes sense,
or maybe I am wrong and people will need to just manually install readline
themselves.
