[PATCH v4 0/2] submodule: fix handling of relative superproject origin URLs

This series ensures that git submodule handles relative superproject origin URLs correctly.

Current behaviour:

* does not guarantee that the submodule.{name}.url property of the superproject is 
always confgured with a valid path to the submodule's origin repo that is 
relative to the working tree of the superproject.
* does not guarantee that the remote.origin.url property of the submodule is
always configured with a valid path to the submodule's origin repo that is 
relative to the working tree of the submodule
* errors out (origin URL = foo) even though this is not strictly necessary.

These changes:

* guarantee that the configured paths are always valid relative paths
from the working tree of the repo containing to the configuration to the
origin repo of the described submodule.
