Not sure what is going on. I should have checked out the stable/13 branch and cherry picked 95940a2d2442c4ae47013b8ddb5bfb8bb5e40b39. Then why the file edited here is still in main?

These changes are already in, with D39368 - https://reviews.freebsd.org/source/src/browse/main/share/misc/committers-src.dot - not?

Why another Diff?

See my comment above. I am trying to MFC the change into stable/13. But turns out the cherry pick is still in main. However, my local git branch shows below it is in stable/13.

$ git branch
  main
* stable/13

$ git status
On branch stable/13
Your branch is ahead of 'freebsd/stable/13' by 1 commit.
  (use "git push" to publish your local commits)

nothing to commit, working tree clean

Looks I need to specify the stable/13 branch in arc. Close this review now.
