+Subject: [PATCH] Avoid ffmpeg licences/credits checking generated autorename_ files.
+
+We generated these renames as a fix for http://crbug.com/495833. The
+generated rename contains no license or credits info and should be
+skipped to avoid confusing license/credits scripts. Care must be
+taken to not also skip the underlying include file from upstream ffmpeg.
