Thank you!

This change should be grafted, since ~2000 packages will be affected.

There's a recent example of appending patches in a replacement package:

+    (source
+      (origin
+        (inherit (package-source libsndfile))
+        (patches
+          (append
+            (origin-patches (package-source libsndfile))
+            (search-patches "libsndfile-CVE-2017-8361-8363-8365.patch"
+                            "libsndfile-CVE-2017-8362.patch")))))))
