 For diffs to work properly, we need to check the input document and the
 output document in their entirety, including their signatures.  Otherwise,
 the diffs won't apply correctly when they change the signatures!

 But for *that* to work, we need to do what we can to minimize the odds
 that anybody has a consensus with different signatures, or with signatures
 organized differently.

 As an alternative, we could change the diff format so that it always
 replaces all the old signatures with the new ones.
