M-h f while
returns:
"while is a special form in `C source code'.
(while TEST BODY...)
If TEST yields non-nil, eval BODY... and repeat.
The order of execution is thus TEST, BODY, TEST, BODY and so on
until TEST returns nil."
The documentation does not say that the form itself returns nil.

(I'm going through old bug reports that have unfortunately not gotten
any responses.)
The manual does:
The value of a @code{while} form is always @code{nil}.
So I guess the doc string should, too. I've now made this change in
Emacs 27.
