title: Bash variable set at the end of a rake command
body: <p>I see this in a script:</p>
  
  <pre><code>rake -f some_rake_file raketask1 raketask2 --trace CI_REPORTS=/some/directory
  </code></pre>
  
  <p>CI_REPORTS is a bash shell variable. It's set at the end of the statement on the same line as the rake command. How does that work? I expected to see this:</p>
  
  <pre><code>CI_REPORTS=/some/directory
  rake -f some_rake_file raketask1 raketask2 --trace
  </code></pre>
