Yeah. It was a mistake that we gave a short-and-sweet "-u" too
hastily to a relatively useless form that does not take any argument
and ended up needing to resort to the optional-arg trick.

Sorry, but I am not sure what you mean by this comment.
Your illustration patch lets you say "no, 'no' is not a pathspec"
with
git status -u no --
and "I want the unadorned -u and am asking about stuff in the 'no'
subdirectory" with
git status -u -- no
but in the former, it would not make 'no' an arg to '-u' by saying
"'no' is not a pathspec", would it?
