[PATCH v2 00/11] decoupling a submodule's existence and its url

Differences from v1:
* Reordered some of the patches
* added submodule.<name>.active boolean config option which can be used to do
  more fine grain selection of submodules while still decoupling the existence
  from the URL.
* submodule.<name>.active has precedence over the pathspec stored in
  submodule.active

Brandon Williams (11):
  submodule--helper: add is_active command
  submodule status: use submodule--helper is-active
  submodule deinit: use most reliable url
  submodule sync: use submodule--helper is-active
  submodule--helper clone: check for configured submodules using helper
  submodule: decouple url and submodule existence
  submodule update: add `--init-active` switch
  clone: add --submodule-spec=<pathspec> switch
  completion: clone can initialize specific submodules
  submodule--helper init: set submodule.<name>.active
  submodule add: respect submodule.active and submodule.<name>.active
