My gut reaction to this is that it is ugly and maybe we should rather have
a --no-tags[=<repo-spec>].
We have had the discussion for e.g. git-push, for which we would like to
have a way to specify to push the superproject, or some submodules or
all of them, or just the superproject and changed submodules,
such that there we have a "git push --recurse-submodules= \
[check|on-demand|only|no]" which comes close to what I mean by
"repo-spec".

Okay, that can be added later if desired.

Quite a lot of collaboration. ;)

Here you would need to also push --no-tags-submodules to keep it recursive?

Name is good as it describes the niche we're looking at.
(previous commit sounded as if you wanted to introduce
a plain clone-submodules.sh)

This can be written easier with
test_create_repo sub &&
test_commit -C sub subcommit1 &&
test_commit -C sub subcommit2 &&
test_commit -C sub subcommit3 &&
Most submodule code thought naming a submodule
"sub" was a good idea. I also wrote such code. But please
let's stop with this tradition. Name the submodule after your
favorite dish (that hopefully doesn't have "sub" in its name),
as it is much easier to read the test code when there are fewer
strings "sub".

Why do we need to strip the refnames here? Full ref names ought to be fine?
Specifically when testing in combination of single-branch (does that imply
any tags setting), I'd rather expect an rstrip and then counting refs/heads
and refs/tags.
