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".
