    Actually, can you make the signature be detached and a seperate
    object? Ie, add a signature object in its own right, distinct from
    tag. They could then:

    - be used to sign any kind of object
    - allow objects to be signed by multiple people

    Ideally, there'd be an index of signature objects by the SHA-1 sum of
    the object they sign, as the signed object should not refer to the
    signature (or the second of the above is not possible).

    The latter of the two points would, in combination with the former,
    allow for cryptographic 'signed-off-by' chains. If a 'commit' is
    you know its time to pull it. Would also work for things like "fixes
    only" trees, where (say) a change must be approved by X/2+1 of a
    group of X hacker providing oversight -> looking up the commit
    object's signatures would tell you whether it was approved.

    No idea whether this is possible or practical. :) But it would be
    good for future flexibility to avoid including the signature in the
    object being signed.
