One thing that I found troubling is the ../../../ "three levels up"
is hardcoded. Would it be always true for any value of "$1"? If
the submodule is bound to the superproject at sub/dir/, not at dir/,
for example, would it have to change?
I am not saying that we must support artibrary cases, but if there
is such a limitation in the implementation, people who will use the
helper in their new tests want it at least documented, I think.
