Wysiwyg codemirror doesn't work in IE7 + solution

Wysiwyg codemirror breaks in IE7.

To resolve this, remove the last comma in the codemirror-array of /sites/all/modules/wysiwyg_codemirror/tinymce/codemirror/js/dialog.js.

    codemirror = CodeMirror.fromTextArea(f.code, {
      height: "405px",
      width: "95%",
      parserfile: "parsexml.js",
      stylesheet: "/sites/all/modules/wysiwyg_codemirror/tinymce/codemirror/js/codemirror/css/xmlcolors.css",
      path: "/sites/all/modules/wysiwyg_codemirror/tinymce/codemirror/js/codemirror/js/",
      reindentOnLoad: true, 
      continuousScanning: 500,
      lineNumbers: true,
      textWrapping: true,
      indentUnit: 3,
      tabMode: 'shift',  <--- remove this comma
    });
