test_description='git rebase interactive

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

Initial setup:

     one - two - three - four (conflict-branch)
   /
 A - B - C - D - E            (master)
 | \
 |   F - G - H                (branch1)
 |     \
 |\      I                    (branch2)
 | \
 |   J - K - L - M            (no-conflict-branch)
  \
    N - O - P                 (no-ff-branch)

 where A, B, D and G all touch file1, and one, two, three, four all
 touch file "conflict".
