Let me add another to that list ;-)
I have this prefix; please enumerate all known objects that share it.
I do not know the value of the first two in your list. If it is a
known object, then you throw it at "git show", "git cat-file -t" and
dig from there. If it is not known, there is nothing more to do.
I do not know if "need" is the right word, but I hope that you
realize the last two among the four you listed need the equivalent
of "git fsck". It is an expensive operation.
