   * lisp/gnus-art.el (gnus-treat-display-face): Fix docstring link to point to
   `(gnus)Face', not `(gnus)X-Face'.

   * lisp/nnimap.el (nnimap-retrieve-headers-progress): Handle edge case where
   `headers' is nil.  This can occur if the IMAP server does not have
   permissions to read messages from a folder, but can write new messages
   to the folder.
   (nnimap-request-article-part): Do not insert `data' if it is nil.

   * lisp/imap.el (imap-parse-fetch): Courier can insert spurious blank
   characters which will confuse `read', so skip past them.
