+ 9. New global option "gnutls_enable_pkcs11", defaults false.  The GnuTLS
+    rewrite in 4.80 combines with GnuTLS 2.12.0 or later, to autoload PKCS11
+    modules.  For some situations this is desirable, but we expect admin in
+    those situations to know they want the feature.  More commonly, it means
+    that GUI user modules get loaded and are broken by the setuid Exim being
+    unable to access files specified in environment variables and passed
+    through, thus breakage.  So we explicitly inhibit the PKCS11 initialisation

+10. The "acl = name" condition on an ACL now supports optional arguments.
+    New expansion item "${acl {name}{arg}...}" and expansion condition
+    "acl {{name}{arg}...}" are added.  In all cases up to nine arguments
+    can be used, appearing in $acl_arg1 to $acl_arg9 for the called ACL.
+    Variable $acl_narg contains the number of arguments.  If the ACL sets
+    a "message =" value this becomes the result of the expansion item,
+    or the value of $value for the expansion condition.  If the ACL returns
+    accept the expansion condition is true; if reject, false.  A defer
+    return results in a forced fail.

+    handled by routers/transports.

+    "aaaa" and "a" lookups is done and the full set of results returned.
