With this and 4/4 applied, the documentation still says "--cached"
is the only supported option.

Does it really make sense to pass all of these?  I understand "-z"
and I suspect things like "-t" and "-v" that affect "how" things are
shown may also happen to work, but I am not sure how much it makes
sense for options that affect "what" things are shown.

What does it even mean to ask for say "--unmerged" to be shown, for
example, from the superproject?  Recurse into submodules whose cache
entries in the index of the superproject are unmerged, or something
else?

I am inclined to say that it is probably better to keep the
"--cached only" as documented, at least on the "what are shown"
side.

Thanks.
