By this, do you mean that git-submodule.sh inserts "--" when it invokes "git submodule--helper"?

I'm not sure about this one. "--recursive" isn't a top level option, and 15fc56a8536 doesn't seem to suggest that it was meant to be one (but I did realize that git-submodule.txt documents all of the options to all subcommands, which is very confusing.) > > Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx> > --- > t/t7400-submodule-basic.sh | 26 ++++++++++++++++++++++++++ > 1 file changed, 26 insertions(+) > > diff --git a/t/t7400-submodule-basic.sh b/t/t7400-submodule-basic.sh > index e7cec2e457a..b858871a953 100755 > --- a/t/t7400-submodule-basic.sh > +++ b/t/t7400-submodule-basic.sh > @@ -14,6 +14,32 @@ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME > > . ./test-lib.sh > > +test_expect_success 'submodule usage: -h' ' > + git submodule -h >out 2>err && > + grep "^usage: git submodule" out && > + test_must_be_empty err > +' > + > +test_expect_success 'submodule usage: --recursive' ' > + test_expect_code 1 git submodule --recursive >out 2>err && > + grep "^usage: git submodule" err && > + test_must_be_empty out > +' > + > +test_expect_success 'submodule usage: status --' ' > + test_expect_code 1 git submodule -- && > + test_expect_code 1 git submodule --end-of-options > +' > + > +for opt in '--quiet' '--cached' > +do > + test_expect_success "submodule usage: status $opt" ' > + git submodule $opt && > + git submodule status $opt && > + git submodule $opt status > + ' > +done > + > test_expect_success 'submodule deinit works on empty repository' ' > git submodule deinit --all > ' > -- > 2.37.1.1167.g38fda70d8c4
