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".
