[issue18279] IDLE Unit test for RstripExtension.py

[Terry J. Reedy]

Terry J. Reedy added the comment:

A simple change to RstripExtension.py fixed the marking of unchanged files as changed. I also removed a useless extra iteration. Having a test makes it possible to do things like this without breaking what already worked.

----------
dependencies:  -Idle: mock Text class and test thereof
resolution:  -> fixed
