Here it is.  Now the remote defaults to $(get_default_remote) with an
optional override via submodule.<name>.remote.

Changes since v5:

* New patch 1 for easy config variable setup.
* Minor tweaks and rewordings in patches 2 and 3 (v5 patches 1 and 2).
* New patch 4 adding submodule.<name>.remote.

I'm fine with squashing patches 1, 2, and 4 together, if people prefer
a more compact series.

W. Trevor King (4):
  submodule: add get_submodule_config helper funtion
  submodule update: add --remote for submodule's upstream changes
  submodule add: If --branch is given, record it in .gitmodules
  submodule update: add submodule.<name>.remote config option
