[PATCH v6 0/7] submodule--helper credential.* pass into submodule

[Jacob Keller <jacob.e.keller@intel.com>]

From: Jacob Keller <jacob.keller@gmail.com>

This series implements ability to pass the credential.* configuration
variables from the command line directly into the submodule. The other
patches in this series are small fixups noticed along the way.
