# NOTE:
#
# This test is particular because there is only a single commit in the upstream superproject
# 'parent' (which adds the submodule 'a-submodule'). The clone of the superproject
# ('child') hard-resets its branch to a new root commit with the same tree as the one
# from the upstream superproject, so that its branch has no merge-base with its
# remote-tracking counterpart, and then calls 'git pull --recurse-submodules --rebase'.
# The result is that the local branch is reset to the remote-tracking branch (as it was
# originally before the hard-reset).
# The only commit in the range generated by 'submodule.c::submodule_touches_in_range' and
# passed to 'submodule.c::collect_changed_submodules' is the new (regenerated) initial commit,
# which adds the submodule.
# However, 'submodule_touches_in_range' does not error (even though this commit adds the submodule)
# because 'combine-diff.c::diff_tree_combined' returns early, as the initial commit has no parents.
