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

  11Initial 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".
