It seems there is a NEWS entry with CRLF endings: https://github.com/python/cpython/actions/runs/24613765518/job/71972503301?pr=148739 |

I resolved a conflict in a PR using the GitHub web editor, using Chrome on macOS, which involved moving lines around. However, GitHub also changed the LF endings to CRLF:
7208828
So I had to fix it locally:

I don't know why GitHub does this. It doesn't seem to do it for simple edits, moving lines appears to be important.
A similar thing happened recently with f938f01, which only affected a few lines.
We added extra linting (#148336) to help catch stuff like this, but it only checks that the endings match the majority. That won't pick up whole file changes!
Anyway, doing some tests, GH does at least respect
.gitattributes, so let's declare it.
