gnus: Support for IMAP Extensions

 
 6.3.4 Support for IMAP Extensions
 ---------------------------------
 
 If you’re using Google’s Gmail, you may want to see your Gmail labels
 when reading your mail.  Gnus can give you this information if you ask
 for ‘X-GM-LABELS’ in the variable ‘gnus-extra-headers’.  For example:
 
      (setq gnus-extra-headers
            '(To Newsgroups X-GM-LABELS))
 
    This will result in Gnus storing your labels in message header
 structures for later use.  The content is always a parenthesized
 (possible empty) list.
