Re: [PATCH v3] builtin/reflog: respect user config in "write" subcommand

> The reflog write recognizes only GIT_COMMITTER_NAME and
> GIT_COMMITTER_EMAIL environment variables, but forgot to honor the
> user.name and user.email configuration variables, due to lack of
> repo_config() call to grab these values from the configuration files.
> 
> The test suite sets these variables, so this behavior was unnoticed.
> 
> Ensure that the reflog write also uses the values of user.name and
> user.email if set in the Git configuration.
