It wants me to format this JS, but when I do it "git cl format" actually formats the entire file instead of the few lines I actually touched. It also does terrible things like inserting massive amounts of whitespace and squishing all of the text to the far right.

I don't think we should require git cl format of the JS inside LayoutTests in general, but it also shouldn't incorrectly format the file or touch every line outside the ones the patch did.

ex.

-Markup._namespace = function(node)
-{
-    if (Markup._NAMESPACE_URI_MAP[node.namespaceURI])
-        return Markup._NAMESPACE_URI_MAP[node.namespaceURI] + ' ';
-    return '';
+                                    Markup._namespace =
+                                        function(node) {
+  if (Markup._NAMESPACE_URI_MAP[node.namespaceURI])
+    return Markup._NAMESPACE_URI_MAP[node.namespaceURI] + ' ';
+  return '';
 }
 
-Markup._dumpCalls = 0
+                                        Markup._dumpCalls = 0
