bug#23761: 25.0.94; Gnus wont exit when .newsrc.eld file is modified externally

[Live System User]

Hi,

        I ran Gnus in two different instances one of which was
        running undisturbed for over a week.

        When I went to exit it, if, of course, warned me:

/home/liveuser/.newsrc.eld was updated externally after Thu 02 Jun 2016
04:26:45 AM EDT, save? (y or n) n

         I type "n" to not save the state file and "y" to continue
         exiting Gnus anyway and recieved the error:
         
Debugger entered--Lisp error: (error "Couldn’t save /home/liveuser/.newsrc.eld: 
updated externally")
  signal(error ("Couldn’t save /home/liveuser/.newsrc.eld: updated externally"))
  error("Couldn't save %s: updated externally" "/home/liveuser/.newsrc.eld")
  gnus-save-newsrc-file()
  gnus-group-exit()
  funcall-interactively(gnus-group-exit)
  call-interactively(gnus-group-exit nil nil)
  command-execute(gnus-group-exit)

        Gnus did not exit and rremained in the *Group* buffer.

        Thanks.
