Well, I admit, I haven't tested this enough. Specifically, there is a
bug in this patch (both versions); please delete it.


I accept your criticism of my latest patches, they truly are of inferior
quality. I deeply apologize for having taken up more of your time than I
should have.


Allow me to explain my situation:

I work with a highly modified version of IDLE to which I have added many
features, and which is also used daily by ~10 friends and colleagues.
Many of these patches are my attempt to contribute the more mature and
successful changes/features back to CPython. However, the completion
code differs greatly from the CPython version, making porting changes a
large effort, requiring me to re-implement many things, as well as go
once more through the process of testing and debugging.

This is really a great deal of work and I have been eager to contribute
some of the better features. While I have tried to be methodical,
thorough and test everything, I seem to still have been too hasty. I
must tell you that I spent many hours preparing the last few patches,
but I realize that doing half a job is worse than not doing it at all.

In the future I will test every change much more thoroughly before
posting it as a patch.
