Re: [PATCHv3 2/6] send-pack: Rename ref_update_to_be_sent to check_to_send_update

> This renames ref_update_to_be_sent to check_to_send_update and inverts
> the meaning of the return value. Having the return value inverted we
> can have different values for the error codes. This is useful in a
> later patch when we want to know if we hit the CHECK_REF_STATUS_REJECTED
> case.
