Very nicely written test sequence with pictures.  I wish all the tests
were written like this.

If this is the first one in the series, you may want to mark these tests
with test_expect_failure and make a later patch that changes the behaviour
of rebase-i-p include updates to the test script to turn expect-failure
into expect-success.
