Well, yes.

      ((assign)
       (string-append
        (format #f "@item Sets translator property @code{~a} to" name-sym)
        (if (pretty-printable? value)
            (format #f ":~a\n" (scm->texi (car args)))
            (format #f " ~a.\n" (scm->texi (car args))))))

Here (pretty-printable? value) should likely be (pretty-printable? (car
args)) .
