[3.9] bpo-44885: Correct the ast locations of f-strings with format specs and repeated expressions (GH-27729) by pablogsal · Pull Request #27744 · python/cpython

@pablogsal does the new tests work under -X oldparser? I am not sure if we have a buildbot that runs with -X oldparser, though I'd assume these would fail since now two parsers disagree about the locations.

We have one that probably will fail soon :(

I will fix it if I can, but I have already removed some tests to avoid failures. If I cannot fix it we may need to revert :(
