title: How to be explicit about intentional word splitting?
body: <p>I'm running <a href="https://www.shellcheck.net" rel="noreferrer"><strong>shellcheck</strong></a> on my scripts and often get this warning (which in this case is correct, because <code>cd foo bar baz</code> makes no sense):</p>
  <pre><code>cd ${SOME_DIR} || exit 1
     ^-- SC2046: Quote this to prevent word splitting.
  </code></pre>
  <p>This warning is mostly a good one. One exception when the variable contains multiple arguments:</p>
  <pre><code>gcc ${OPTIONS} ...
      ^-- SC2046: Quote this to prevent word splitting.
  </code></pre>
  <p>Is there a convention for being more explicit about intentional word splitting, possibly avoiding this shellcheck warning?</p>
