I see, that's what I've been missing, thanks. So it's the middle path
(as any other commonly used VCS for that matter, expect maybe darcs?;
patch queues and rebasing count but it's a hack, not something properly
supported by the design of Git, since at this point the development
cannot be fully distributed).

I also assume that given this is the case, the big diff does really not
serve any purpose besides human review?

But somewhere else in the thread it's been said that bundles can also
contain merges. Does that means that bundles can look like:

   1
  / \
 2   4
 |   | _
 3   5  |
  \ /   | a bundle
   6    |
       ~

In that case, against what the big diff from 6 is done? 2? 4? Or even 1?
