As part of removing "flavour" classes in#31691, I changed pathlib'sglob() implementation: previously it usedre.IGNORECASE to implement case-insensitive matches, whereas after it calledos.path.normcase() on the pattern and the paths. The new behaviour is a little slower, and I think we should restore the previous implementation.
