Fixes gohugoio/hugo#9446

OK, let's start over, I was a little fast earlier. Why does this change require change in 4 files? I suspect some of them are formatting changes, but with thousands of lines changed, it's not possible for me to decide.

If you can narrow down this change set to the 1 file (+ test) that is touched by this change, I will merge it.

And yes, I understand your point, but dont't have the time to figure out why your go generate generates different from mine, and I certainly cannot spend time on the 10K line diff.

OK, I guess the go generate script does not apply gofmt, which would explain the diff, but I still don't see why you would need to regenerate these files for this particular patch.

I apologize. I didn't see any harm in doing so. I have reverted those changes.

The bigger the diff, the harder is to merge.
