#
Add a new "add-config" subcommand to `git submodule--helper` with the goal of converting part of the shell code in git-submodule.sh related to `git submodule add` into C code. This new subcommand sets the configuration variables of a newly added submodule, by registering the url in local git config, as well as the submodule name and path in the .gitmodules file. It also sets 'submodule.<name>.active' to "true" if the submodule path has not already been covered by any pathspec specified in 'submodule.active'. This is meant to be a faithful conversion from shell to C, with only one minor change: A warning is emitted if no value is specified in 'submodule.active', ie, the config looks like: "[submodule] active\n", because it is an invalid configuration. It would be helpful to let the user know that the pathspec is unset, and the value of 'submodule.<name>.active' might be set to 'true' so that they can rectify their configuration and prevent future surprises (especially given that the latter variable has a higher priority than the former). The structure of the conditional to check if we need to set the 'active' toggle looks different from the shell version -- but behaves the same. The change was made to decrease code duplication. A comment has been added to explain that only one value of 'submodule.active' is obtained to check if we need to call is_submodule_active() at all. This is part of a series of changes that will result in all of 'submodule add' being converted to C.
