The new switch `--init-active` initializes the submodules which are
configured in `submodule.active` and `submodule.<name>.active` instead
of those given as command line arguments before updating. In the first
implementation this is made incompatible with further command line
arguments as it is unclear what the user means by
git submodule update --init --init-active <paths>
This new switch allows users to record more complex patterns as it saves
retyping them whenever you invoke update.

If `--recursive` is specified, this command will recurse into the
