+ * The format.attach configuration variable lacked a way to override a
+   value defined in a lower-priority configuration file (e.g. the
+   system one) by redefining it in a higher-priority configuration
+   file.  Now, setting format.attach to an empty string means show the
+   patch inline in the e-mail message, without using MIME attachment.
