[Message part 1 (text/plain, inline)]

Hello again,

I'd like to bump this report, if only because I've finally taken the
time to try out Eric Abrahamsen's gnus-mock package on GNU ELPA.  This
allowed me to make a reproducible test case with this simple config:

> (setq gnus-summary-make-false-root 'dummy)

I've attached an example .mbox saved from gnu-emacs-help; you can
reproduce my issue by saving it somewhere, then evaluating this in the
same directory:

#+begin_src elisp
(let ((gnus-mock-init-file (expand-file-name "gnus-dummy-init.el"))
      (gnus-mock-emacs-program (expand-file-name "src/emacs" source-directory))
      (mbox (expand-file-name "gnu-emacs-help.mbox" default-directory))
      (init-template "
(setq gnus-summary-make-false-root 'dummy)
(gnus)
(gnus-group-make-doc-group \"%s\" nil)
(gnus-group-select-group)
"))
  (with-temp-buffer
    (insert (format init-template mbox))
    (write-file "gnus-dummy-init.el"))
  (package-initialize)
  (gnus-mock-start))
#+end_src

Right now, Gnus produces this:

   :                             : Re: How to get the actual face attribute?
 .     [  67: Yuan Fu                ] Re: How to get the actual face attribute?
 .     [  28: Yuan Fu                ] 

With my patch (re-attached, with bug number for convenience), Gnus
produces this:

   :                             : Re: How to get the actual face attribute?
 .     [  67: Yuan Fu                ] 
 .     [  28: Yuan Fu                ] 


Let me know if there's anything wrong with the patch, or with my
understanding of the situation.

Thank you for your time.
