Re: [PATCH 3/5] submodule: export sanitized GIT_CONFIG_PARAMETERS

> Commit 14111fc (git: submodule honor -c credential.* from
> command line, 2016-02-29) taught git-submodule.sh to save
> the sanitized value of $GIT_CONFIG_PARAMETERS when clearing
> the environment for a submodule. However, it failed to
> export the result, meaning that it had no effect for any
> sub-programs.
