Lint failed because news item needed newline. I should have replaced default "Update ..." message as change is not visible in diffs.

I will make unrelated config.py correction in a separate PR.

I will change this to move fixup code to a new function in idlelib.util and then conditionally import and call function.

[terryjreedy]

Wait for now.

Ignore change request; I made all changes I think are needed. After separate config patch, I had to fix merge conflict and decided to make additional change here. Please pull changes to your system and test that revised code works.
