This function returns @code{t} if @var{object} is either 0 or 1.
@end defun
-@defun bit-vector &rest objects
+@defun bit-vector &rest bits
This function creates and returns a bit vector whose elements are the
-arguments @var{objects}. The elements must be either of the two
+arguments @var{bits}. Each argument must be a bit, i.e. one of the two
integers 0 or 1.

-@defun make-bit-vector length object
+@defun make-bit-vector length bit
This function creates and returns a bit vector consisting of
-@var{length} elements, each initialized to @var{object}.
+@var{length} elements, each initialized to @var{bit}, which must be
+one of the two integers 0 or 1.
