This backend has been deprecated in favor of `git rebase --rebase-merges`. In preparation for dropping it, let's remove all the regression tests that would need it.

# There are a few bugs in the rebase with regards to the subtree strategy, and
|
|
# this test script tries to document them. First, the following commit history
|
|
# is generated (the onelines are shown, time flows from left to right):
|
|
#
|
|
# topic_1 - topic_2 - topic_3
|
|
# \
|
|
# README ---------------------- Add subproject main - topic_4 - files_subtree/topic_5
|
|
#
|
|
# Where the merge moves the files topic_[123].t into the subdirectory
|
|
# files_subtree/ and topic_4 as well as files_subtree/topic_5 add files to that
|
|
# directory directly.
|
|
#
|
|
# Then, in subsequent test cases, `git filter-branch` is used to distill just
|
|
# the commits that touch files_subtree/. To give it a final pre-rebase touch,
|
|
# an empty commit is added on top. The pre-rebase commit history looks like
|
|
# this:
|
|
#
|
|
# Add subproject main - topic_4 - files_subtree/topic_5 - Empty commit
|
|
#
|
|
# where the root commit adds three files: topic_1.t, topic_2.t and topic_3.t.
|
|
#
|
|
# This commit history is then rebased onto `topic_3` with the
|
|
# `-Xsubtree=files_subtree` option in two different ways:
|
|
#
|
|
# 1. without specifying a rebase backend
|
|
# 2. using the `--rebase-merges` backend
