+18. It is now possible to use newline and other control characters (those with
+    values less than 32, plus DEL) as separators in lists. Such separators must
+    be provided literally at the time the list is processed, but the string
+    expansion that happens first means that you can write them using normal
+    escape sequences. For example, if a new-line separated list of domains is
+    generated by a lookup, you can now process it directly by a line such as
+    this:
+
+      domains = <\n ${lookup mysql{.....}}
+
+    This avoids having to change the list separator in such data. Unlike
+    printing character separators, which can be included in list items by
+    doubling, it is not possible to include a control character as data when it
+    is set as the separator. Two such characters in succession are interpreted
+    as enclosing an empty list item.
