Sanitize for_each_reflog_ent()
It used to ignore the return value of the helper function; now, it expects it to return 0, and stops iteration upon non-zero return values; this value is then passed on as the return value of for_each_reflog_ent(). Further, it makes no sense to force the parsing upon the helper functions; for_each_reflog_ent() now calls the helper function with old and new sha1, the email, the timestamp & timezone, and the message.
