special formatting directives for printf

(printf "Hello, ~a.\n" "World")  ;; => Hello, World

~a.\n

There is no lowercase `a' special formatting directive or a
`dot .'  shown at
https://api.call-cc.org/5/doc/chicken/format/printf.

Is that a typo? s/b ~A ?? Is the . a typo as well?

The \n is explained though. TIA ...
