Re: master a283996: Add command for customizing current newsticker feed

[Eli Zaretskii]

The new code installed by this change triggers a warning:

  In newsticker-customize-feed:
  net/newst-backend.el:656:46: Warning: reference to free variable `feed-name'

And this code looks strange to me:

  +(defun newsticker-customize-feed (feed-name)
  +  "Open customization buffer for `newsticker-url-list' and jump to 
FEED-NAME."
  +  (interactive
  +   (list (completing-read "Name of feed or group to edit: "
  +                          (append (mapcar #'car newsticker-url-list)
  +                                  nil t feed-name))))

Look at the arguments of 'append': what is that supposed to do?

And how can the 'interactive' form reference the argument list that
it's supposed to generate?  What am I missing?

Thanks.
