Impressive!  Thanks.

I tend to forget the -s when doing anything but "git commit" (and this
came from "git am").  And then I try to fix it manually.  Forgetting
that I'm unable to type a three-letter word with less than four errors.

A bit surprised checkpatch didn't catch it.  I guess it's happy with one
SoB, and silently accepting all unknown tags.

Yes. Will fix.
