Nope that's not what we want I think.
Let me one more time give the example. Suppose we have a patch for
linux-2.4.20, p-2.4.20.patch and another one p-2.4.22.patch in two
series files.
A developer will change p-2.4.20.patch. The "diff of the 2.4.20 diff"
is not so useful to the 2.4.22 developer, what is useful is:
diff between tree with series upto including p-2.4.20.patch applied
before and after the update to this patch. That is a diff that is quite
likely to go into 2.4.22 without difficulties, to aid updating the
2.4.22 patch.
My descripiton was not precise. You get an incremental diff, not a diff
of a diff.
You could store that diff in a file 1.diff. Then, 1.diff applied on top
of the old a.diff would get you to the new a.diff.
