Merge branch 'sb/submodule-helper-clone-regression-fix' into maint
A partial rewrite of "git submodule" in the 2.7 timeframe changed
the way the gitdir: pointer in the submodules point at the real
repository location to use absolute paths by accident. This has
been corrected.
* sb/submodule-helper-clone-regression-fix:
submodule--helper, module_clone: catch fprintf failure
submodule--helper: do not borrow absolute_path() result for too long
submodule--helper, module_clone: always operate on absolute paths
submodule--helper clone: create the submodule path just once
submodule--helper: fix potential NULL-dereference
recursive submodules: test for relative paths
