gh-95504: Fix sign placement in PyUnicode_FromFormat by philg314 · Pull Request #95505 · python/cpython

Sorry for making you do more work, but it works best if the test refactoring is done first, in a separate pull request, so that:

• the change PR shows what changed in the tests
• something goes wrong, the change can be reverted without the refactoring
• refactoring can be applied to older unfixed versions, if necessary (e.g. wep only need to backport a subset of changes)

No problem, makes sense.

Do you want to split this up? I can also do it, and it wouldn't be too much extra work in addition to a review, but I don't want to “steal your contribution”.

Sure, and for future reference I'll never have a problem with anything like that. Please ping me when the refactor is merged.
