[PATCH v3 0/7] Rebase topology test

Patches are now expected to be dropped iff they are on upstream. I've also followed all of Johannes's other suggestions except for the one about topo-order.

Martin von Zweigbergk (7):
  add simple tests of consistency across rebase types
  add tests for rebasing with patch-equivalence present
  add tests for rebasing of empty commits
  add tests for rebasing root
  add tests for rebasing merged history
  t3406: modernize style
  tests: move test for rebase messages from t3400 to t3406
