The top-level &&-chain checker built into t/test-lib.sh causes tests to
magically exit with code 117 if the &&-chain is broken. However, it has
the shortcoming that the magic does not work within `{...}` groups,
`(...)` subshells, `$(...)` substitutions, or within bodies of compound
statements, such as `if`, `for`, `while`, `case`, etc. `chainlint.sed`
partly fills in the gap by catching broken &&-chains in `(...)`
subshells, but bugs can still lurk behind broken &&-chains in the other
cases.
Fix broken &&-chains in `$(...)` command substitutions in order to
reduce the number of possible lurking bugs.

# This test covers 2 cases in subtree split copy_or_skip code
|
|
# 1) Merges where one parent is a superset of the changes of the other
|
|
# parent regarding changes to the subtree, in this case the merge
|
|
# commit should be copied
|
|
# 2) Merges where only one parent operate on the subtree, and the merge
|
|
# commit should be skipped
|
|
#
|
|
# (1) is checked by ensuring subtree_tip is a descendent of subtree_branch
|
|
# (2) should have a check added (not_a_subtree_change shouldn't be present
|
|
# on the produced subtree)
|
|
#
|
|
# Other related cases which are not tested (or currently handled correctly)
|
|
# - Case (1) where there are more than 2 parents, it will sometimes correctly copy
|
|
# the merge, and sometimes not
|
|
# - Merge commit where both parents have same tree as the merge, currently
|
|
# will always be skipped, even if they reached that state via different
|
|
# set of commits.
