purpose, the argument vector @<v> is scanned \emph{after} the
variable-length argument tail captured in @<ap>.)
- The variable-argument tail is read from the list described by @|* @<ap>|.
+ The variable-argument tail is read from the list described by @|*@<ap>|.
The argument tail is expected to consist of alternating keyword strings (as
ordinary null-terminated strings) and the corresponding values, terminated
by a null pointer of type @|const char~*| in place of a keyword; except
