Is this the "git cl format" output? If not, can you run it and see if the
formatting ends up more like line 35/36?

Fixed, and I applied "git cl format" elsewhere, except for a
few places where "git cl format" didn't seem to do a very good
job like this:

+  virtual void SetAccessibilityPageInfo(
+      PP_PrivateAccessibilityPageInfo* page_info,
+      PP_PrivateAccessibilityTextRunInfo text_runs[],
+      PP_PrivateAccessibilityCharInfo chars[]) = 0;
   static const SingletonResourceID kSingletonResourceID = PDF_SINGLETON_ID;
 };
