Currently we detect the hash algorithm in use by the length of the object ID. This is inelegant and prevents us from using a different hash algorithm that is also 256 bits in length. Since we cannot extend the v2 format in a backward-compatible way, let's add a v3 format, which is identical, except for the addition of capabilities, which are prefixed by an at sign. We add "object-format" as the only capability and reject unknown capabilities, since we do not have a network connection and therefore cannot negotiate with the other side. For compatibility, default to the v2 format for SHA-1 and require v3 for SHA-256. In t5510, always use format v3 so we can be sure we produce consistent results across hash algorithms. Since head -n N lists the top N lines instead of the Nth line, let's run our output through sed to normalize it and compare it against a fixed value, which will make sure we get exactly what we're expecting.
