Ugh. (I should have tested more than just t0060).
The underlying issue is two fold:
* in t3600 we'd need
diff --git a/t/t3600-rm.sh b/t/t3600-rm.sh
index d046d98..545d32f 100755

because the sub-submodule URL is actually the same as the submodule
(because we'd test lazily)
This looks ok from a bug fixers perspective.
However in t7403, we have a construct like:
git clone . super
which then results in
git -C super remote -v
...../git/t/trash directory.t7403-submodule-sync/. (fetch)
And the commit message of this patch claimed we'd never use
the /. syntax ourselves. (We could argue the stupid users in the test
suite are doing it wrong, because in practice nobody would use clone
to create a nested repository? Not sure I agree.)
However instead of fixing the levels of nesting, the fix is as easy as:
diff --git a/t/t7403-submodule-sync.sh b/t/t7403-submodule-sync.sh
index 0726799..525d32b 100755

Same goes for t740{6,7} as well as t7506.
I think this change to the test suite is not warranted, because
we want to have the current behavior as-is as it seems like a nice
hack:
* Maybe we'd want to think about checking for the URL in git clone
normalize the URL before configuring remote.origin.URL
* an often observed work flow for submodule tests seems:
mkdir sub1 &&
git -C sub1 init &&
...
git clone . super &&
git -C super submodule add ../sub1
... # the ../sub1 looks intuitively correct
# because from the current directory which is
# super the relative path is ../sub1
#
# However in reality this ought to be a relative URL,
# and as super sits in the same directory as sub1
# ./sub1 would be "correct" according to the documentation
# However as the super remote URL ends with /.
# we had a bug that we needed to add one layer of unnesting
# and that is how ../sub1 worked.
Not sure about this patch any more.
