It used to be test-column. But we would need an external program to

Hrm, I was hoping that we don't have to resort to a hacky implementation
like that; upload-pack/receive-pack that are not run directly by the end
users but having to be somewhere in path were bad enough, but they were
very much about git.
But at least with your series, "git column" is as invisible as git-sh-setup
and git-stripspace by being marked as purehelpers, so your patch may be
the best we could do. I dunno.
