By the way, while it is a very good idea to die upon

	$ git submodule deinit --all no-only-this-one

it may not be too bad if we demoted the output to "info" with clean
no-op exit when the user said

	$ git submodule deinit

IOW, the latter part _might_ be better if it were

	if test $# = 0 && test -z "$deinit_all"
	then
		echo >&2 "info: not deinitializing anything."
                echo >&2 "info: Use --all to deinitialize all submodules."
                exit 0
	fi

given that this is really about preventing mistakes from doing mass
destruction.
