[PATCH 11/19] tests: fix broken &&-chains in `$(...)` command substitutions

From
Eric Sunshine <sunshine@sunshineco.com>
Date
Dec 9, 2021, 05:11 UTC
Message-ID
<20211209051115.52629-12-sunshine@sunshineco.com>
In-Reply-To
<20211209051115.52629-1-sunshine@sunshineco.com>

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.
