   7
   8 This test runs git rebase "interactively", by faking an edit, and verifies
   9 that the result still makes sense.

  11 Initial setup:
  12
  13      one - two - three - four (conflict-branch)
  14    /
  15  A - B - C - D - E            (master)
  16  | \
  17  |   F - G - H                (branch1)
  18  |     \
  19  |\      I                    (branch2)
  20  | \
  21  |   J - K - L - M            (no-conflict-branch)
  22   \
  23     N - O - P                 (no-ff-branch)
  24
  25  where A, B, D and G all touch file1, and one, two, three, four all
  26  touch file "conflict".
