All of the patches in this series are malformed. There should be a
"---" line right here below your sign-off. The "---" line is
recognized by git-am/git-apply as separating the commit message from
the actual diff(s).

It is a very well-established custom in Git tests for the files handed
to test_cmp() to be named "expect" and "actual", so this change is not
the most desirable. What you can do instead is:

    git diff-tree -M -r --name-status HEAD^ HEAD >output &&
    sed -e "s/R[0-9]*/RNUM/" output >actual &&

which allows you to leave the test_cmp() line alone, thus (as a bonus)
makes the patch less noisy.
