title: mod_substitute errors out with "line too long"
body: <p>I am just trying to prepend and append a certain string to Apache responses matching certain filetypes. I thought <code>mod_substitute</code> would do the job, but it errors out all the time with: <code>AH01328: Line too long</code>.</p>
  
  <p>This is what my directive looks like:</p>
  
  <pre><code>&lt;Location "/src"&gt;
      AddType application/javascript .txt .tpl
      AddOutputFilter SUBSTITUTE tpl txt
      SubstituteMaxLineLength 10m
      Substitute "s/([\s\S]*)/export default `$1`/i"
  &lt;/Location&gt;
  </code></pre>
  
  <p>As you can see I also tried to up the limit on <code>SubstituteMaxLineLength</code>, but that seems to have no effects.</p>
  
  <p>Any idea what I am doing wrong, or is there another option to solve this seemingly easy (well, apparently not so) task?</p>
