I am observing git checkout --patch making changes to the wrong lines of a file.
This is with a clean install of git version 2.20.1 on a debian docker
container (image tag 10.0 which is also "latest" as of this writing).
With a diff that looks like the following:
diff --git a/file.txt b/file.txt

Hi Dave
Thanks for the bug report. I've tried to reproduce it on the latest
master, version 2.22.0 and 2.20.1 and am unable to do so. I thought it
might be related to a bug I recently fixed[1] but it does not appear to
be. I've appended the files I used below just in case I made a mistake
translating your patches to files that can be used with git checkout.
Best Wishes
Phillip

Doh, I was doing 'git checkout -p HEAD', when I checkout from the index
I can reproduce the bug and it is fixed by the patch I linked to earlier
which will be in git 2.23.0. That will be released soon (we're at
2.23.0.rc2 at the moment)
Thanks again for taking the time to report the bug
