According to the CL hyperspec:

    (lambda lambda-list [[declaration* | documentation]] form*)
 ==  (function (lambda lambda-list [[declaration* | documentation]] form*))
 ==  #'(lambda lambda-list [[declaration* | documentation]] form*)

And the #' didn't seem to be needed in any of the CL systems I tried.

However, Guy Steele's "Common Lisp, The Language Second Edition",
Section 5.2 states quite explicitly the opposite.  I guess its more
recent than 1990, probably introduced by scheme people who infiltrated
an ANSI draft review by posing as MIT janitors.
