	Gnus gnus-summary-respool-article broken due to gnus-completing-read
Date: Mon, 29 Apr 2013 17:14:58 +0200

Recipe:

In a Gnus Summary buffer, type `B q' (gnus-summary-respool-query) to
"Query where the respool algorithm would put this article."
==> Fine, it displays the expected group.

Now do `B r' (gnus-summary-respool-article) to actually "Respool the
current article."

- Prompt "Backend to use when respooling (default nnml): ", I hit
  RET.  Fine.

- Prompt "Server name: ", TAB gives "no match".  What?  I'm sure that
  I have several nnml backends:

,----[ <f1> v gnus-server-alist RET ]
| gnus-server-alist is a variable defined in `gnus.el'.
| Its value is shown below.

|   [...]
|   (nnml-get-new-mail nil)

I'm sure that this worked correctly in the past, probably before the
changes done WRT `gnus-completing-read' around 2010-09-27.

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.
