In the latest patch, I see:
+   <varlistentry>
+    <term><literal>SKIP ( <replaceable
class="parameter">skip_option</replaceable> = <replaceable
class="parameter">value</replaceable> [, ... ] )</literal></term>

What do we want to indicate by [, ... ]? To me, it appears like
multiple options but that is not what we support currently.
