Could the line endings contain \r as well (e.g. on Windows)?

This data comes from
https://code.google.com/p/chromium/codesearch#chromium/src/chrome/browser/pro...,
wher eit seems that the \n characters are added in code and not read from a
file.

       });
       var win = window.open('about:blank');
       var div = win.document.createElement('div');
-      div.textContent = JSON.stringify(feedbackObj, null, 2 /* spaces */);
+      div.textContent = output.join('\n');
       div.style.whiteSpace = 'pre';
       win.document.body.appendChild(div);
     });
   },
 });
