Hi, Jorgen, I am very glad to make this work and it really took me a lot of time. Unfortunately, I do not know how to generate patch and use svn. However, since the change is very straight forward, I attached this file with email. Please put back the change in future pyreadline release. The emacs environment is set by the emacs automatically. I did not do anything.
