I ran git diff --check HEAD~ on my branch and saw the same warnings.
I don't know much about diff and patch, though.
What is the correct diff command to generate a patch? I used `diff -crB
database.cc database2.cc > crawl-upgrade-saves.patch` and then edited
the header myself.
Searching for 'diff ' or 'patch' on
https://www.gnu.org/software/guix/manual/guix.html doesn't bring up
anything related.

I did some comparison with other files in ./gnu/packages/patches/ and it
seems like `diff -u` generates the format that most files in there have.
But it still leaves one trailing whitespace in empty lines. Other .patch
files have those too.

I attached the commit with the .patch file generated in the diff -u
format instead of diff -c.
