Hmm. I would have thought --no-short would just set it to LONG. That is,
we are no longer NONE at that point, as the user has told us something
on the command line. So we are whatever --no-short is, which is LONG.

But I guess that would wreck

  git status --no-short -z

which currently defaults to porcelain. Which, to be honest, seems a
little crazy to me, but I guess there is no reason to break it.

I am just trying to prevent the future maintenance confusion where a
reader of the code says "Huh? What is the difference between NONE and
UNSPECIFIED?"
