The tests with absolute paths all fail on Windows. The reason is that git.exe sees mangled paths and 'git submodule--helper resolve-relative-url-test' produces mangled paths (that begins with a drive letter), whereas the test script expects POSIX paths. The pattern I currently use to fix this is

test_submodule_relative_url "(null)" "$PWD/addtest" "../repo" "$(pwd)/repo"

(In our test scripts, $PWD is a POSIX style path and $(pwd) is a Windows style path).

With this change, the penultimate case above still fails because the 'home2/..' gets lost somewhere in the actual output, which I still have to debug.

The two cases beginning with '/u//' cannot be tested on Windows. Are they important? Are the doubled slashes intentional?
