[PATCH 0/4] Fix relative path issues in recursive submodules.

[Stefan Beller <sbeller@google.com>]

It took me longer than expected to fix this bug.

It comes with a test and minor refactoring and applies on top of
origin/sb/submodule-helper, such that it can be merged into 2.7, 2.8 as well
as master.

Patch 1 is a test which fails; it has a similar layout as the
real failing repository Norio Nomura pointed out, but simplified to the
bare essentials for reproduction of the bug.

Patch 2&3 are not strictly necessary for fixing the isseu, but it removes
stupid code I wrote, so the resulting code looks a little better.

Patch 4 fixes the issue by giving more information to relative_path,
such that a relative path can be found in all cases.

Thanks,
Stefan
