Can you send above suggestion as formal patch instead? See
Documentation/process/submitting-patches.rst for how to properly submit
patches. And also, use git-send-email(1) when sending them so that patch
corruption (like tabs converting to spaces and line wrapping as in above
diff) doesn't occur.

Thanks.
