Modify curlify through the Plugin system?

First of all I would like to particularly thank you for the well thought design. In particular the Plugin System is really simple and a clever way to provide customization.

Explaining my issue, for a problematic endpoint on my definition I have to send multi-line text/plain on the body. In the code, curlify.js sanitizes the body removing newlines:

if ( request.get("body") ){
    if(type === "multipart/form-data" && request.get("method") === "POST") {
      // ...
    } else {
      curlified.push( "-d" )
      curlified.push( JSON.stringify( request.get("body") ).replace(/\\n/g, "") )
    }
}

But I would like to send the body as is and add "$" for curl to process it properly:

if ( request.get("body") ){
    if(type === "multipart/form-data" && request.get("method") === "POST") {
      // ...
    } else {
      curlified.push( "-d" )
      if(type === "text/plain") {
        curlified.push( "$" )
        curlified.push( request.get("body") )
      } else
        curlified.push( JSON.stringify( request.get("body") ).replace(/\\n/g, "") )
    }
}

Can I achieve this through the plugin system? Or maybe the change qualifies as a pull-request?

Thanks in advance for your care and patience!

Start by reading curlify.js and the Plugin System documentation or entry points mentioned in the issue. Verify how text/plain request bodies are converted into curl arguments, then confirm that multiline text/plain bodies are preserved while other body types retain their current behavior.
