The `ref_transaction_add_update()` creates the `ref_update` struct. To facilitate addition of reflogs in the next commit, the function needs to accommodate setting the `committer_info` field in the struct. So modify the function to also take `committer_info` as an argument and set it accordingly. Signed-off-by: Karthik Nayak <karthik.188@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
