I don't think this is a valid argument.
Using OPT_NOOP_NOARG doesn't require any change in shell script since
the binary still accepts -q|--quiet.
The documentation of --quiet is still valid (since it doesn't print
anything regardless)
The only necessary change in in that C code.

We want to do this because we don't want to whitespace-split "$branch"
Let's say, for some reason, this command was run:
git submodule set-branch --branch "a-branch --branch another" a-submodule
This version will run:
git submodule--helper --branch a-branch --branch another a-submodule
Which will success if there's a branch "another" in the "a-submodule".
While that command should fail because we don't accept refname with
space.
