+By default gpgsm prints distinguished names (DNs) like the Issuer or
+Subject in a more readable format (e.g. using a well defined order of
+the parts).  However, this format can't be used as input strings.
+This option reverts printing to standard RFC-2253 format and thus
+avoids the need to use --dump-cert or --with-colons to get the
+``real'' name.
