+<h2>Automatically derive odd wrapping behavior for your browser</h2>
+
+
+    <p>This is a hack to automatically derive
+    a <code>spanAffectsWrapping</code> regexp for a browser. See the
+    comments above that variable
+    in <a href="../lib/codemirror.js"><code>lib/codemirror.js</code></a>
+    for some more details.</p>
