The breaks in the &&-chain in this test went unnoticed because the "magic exit code 117" &&-chain checker built into test-lib.sh only recognizes broken &&-chains at the top-level; it does not work within `{...}` groups, `(...)` subshells, `$(...)` substitutions, or within bodies of compound statements, such as `if`, `for`, `while`, `case`, etc. Furthermore, `chainlint.sed` detects broken &&-chains only in `(...)` subshells. Thus, the &&-chain breaks in this test fall into the blind spots of the &&-chain linters. Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
