t/chainlint/one-liner: avoid overly intimate chainlint.sed knowledge

sunshineco · gitster · commit 0cca54c70612 · 2021-12-13T14:15:28.000-08:00
The purpose of chainlint.sed is to detect &amp;&amp;-chain breakage only within
subshells (one level deep); it doesn't bother checking for top-level
&amp;&amp;-chain breakage since the &amp;&amp;-chain checker built into t/test-lib.sh
should detect broken &amp;&amp;-chains outside of subshells by making them
magically exit with code 117.

Unfortunately, one of the chainlint.sed self-tests has overly intimate
knowledge of this particular division of responsibilities and only cares
about what chainlint.sed itself will produce, while ignoring the fact
that a more all-encompassing linter would complain about a broken
&amp;&amp;-chain outside the subshell. This makes it difficult to re-use the
test with a more capable chainlint implementation should one ever be
developed. Therefore, adjust the test and its "expected" output to
avoid being specific to the tunnel-vision of this one implementation.
