[Scheme-reports] The error of the number of make-promise's arguments

[Wataru Nakanishi <stibear1996@x>]

Hello WG1 members, 

I found a mistake, the duplicate definition of the make-promise procedure.

In 4.2.5. Delayed evaluation, p.19, it's written

> (make-promise obj)        lazy library procedure

but in 7.3. Derived _expression_ types, p.71,

> (make-promise #f (lambda () <_expression_>))

and

> (define make-promise > (lambda (done? proc) > (list (cons done? proc))))

Which definition is true?
