Fixed.  Though, it's not exactly equal to Emacs's completing-read,
i.e.:

(completing-read "What? " '(foo "bar" (baz))) ;; Doesn't work
(gnus-completing-read "What? " '(foo "bar" (baz))) ;; Works

Please rise a new bug thread if there's a problem in the other
candidates for gnus-completing-read-function.
