[PATCH 1/4] recursive submodules: test for relative paths

[Stefan Beller <sbeller@google.com>]

This was reported as a regression at $gmane/290280. The root cause for
that bug is in using recursive submodules as their relative path handling
seems to be broken in ee8838d (2015-09-08, submodule: rewrite
`module_clone` shell function in C).
