bug#9244: 24.0.50; Server put offline without any prompt

[Stefan Monnier]

Package: emacs,gnus

Occasionally an NNTP (or IMAP) server refuses to answer.  In Emacs-23,
Gnus then prompted me something like "Unable to open server foo, go offline? "

In Emacs-24, this has disappeared at the server is just marked offline
silently (maybe there's a warning message, but if so I never get to
notice it).

Grepping for "go offline" in Gnus, I see that the code that did the
prompting in Emacs-23 was in gnus-int.el but has been removed, although
there is still a comment that refers to it:

% grep 'go offline' emacs-23/lisp/gnus/*.el trunk/lisp/gnus/*.el
emacs-23/lisp/gnus/gnus-int.el:                          "Unable to open server 
%s, go offline? "
emacs-23/lisp/gnus/gnus-int.el:              ;; prompting with "go offline?".  
This is only a concern
trunk/lisp/gnus/gnus-int.el:              ;; prompting with "go offline?".  
This is only a concern
%

Can the prompting be re-introduced, please?
