+Subject: [PATCH] Encode.pm: apply a local patch for CVE-2021-36770
+
+I expect Encode to see a new release today.
+
+Without this fix, Encode::ConfigLocal can be loaded from a path relative
+to the current directory, because the || operator will evaluate @INC in
+scalar context, putting an integer as the only value in @INC.
