[Drew Adams]

1. emacs -Q

2. In *scratch*, type and then eval this: (setq a 42).

3. C-h v a

You get this ephemeral message (check *Messages*):

 Ref found in non-versioned section in "NEWS.22"

   Probably introduced at or before Emacs version 1.1.

 Documentation:
 Not documented as a variable.

What's the prize for finding this begg?
