pointer which terminates the (empty) list.} %
If @<kwfirst> is a null pointer, then @<ap> need not be a valid pointer;
- otherwise, the cursor object @|*
@<ap>| will be modified as the function
+ otherwise, the cursor object @|*@<ap>| will be modified as the function
extracts successive arguments from the tail.
The keyword vector is read from the vector of @|kwval| structures starting
naming their least specific classes; the least specific class in a chain is
called the \emph{chain head}. Suppose that the chain head of the chain
containing $C$ itself is named $H$ (though keep in mind that it's possible
-that .$H$ is in fact $C$ itself.)
+that $H$ is in fact $C$ itself.)
\subsubsection{The ilayout structure}
The @|ilayout| structure contains one member for each of $C$'s superclass
for each of $C$'s superclasses $A$ in the same chain, with $C$ itself listed
first.
