bug#4153: sentence-end properly constructed now?

I am curious if this bug resolves the problem I was encountering with
sentence-forward and sentence-backward in the post 22 versions of emacs
I have had available to me. 

I also ran into it in http://www.emacswiki.org/emacs/auto-capitalize.el 
which irked me enough to try and find the cause of the problem. 

Is sentence-end getting properly constructed now?

... elided ...
;; auto-capitalize.el 
;; 1 Jun 2009: It does not work with Aquamacs 1.7/GNUEmacs 22. Only the first word in the buffer 
;; (or the first word typed after mode activation) is capitalized. 
;; Maybe the code is too old (1998). -- Rikal

;; No.
;; The reason why this code bit is failing is that sentence-end is not
;; getting constructed for some reason in paragraphs.el: 

;; (message "%s" sentence-end) ;; returns null in the post 22 versions of emacs I tried.

;; According to the documentation, sentence-end is supposed to be automatically
;; constructed from the other regexps defined there. It isn't. I did not
;; dig any further. 

;; This also explains why sentence-forward and sentence-backward (M-e,
;; M-a respectively) are not working in the current emacs-snapshot. (I do not have
;; emacs 23.1 installed on the machine I am on, but this does sound like
;; it is also a problem in 23.1)

;; To keep me going I just did a:
;; (setq sentence-end "[.?!][]\"')]*\\($\\| $\\|\t\\| \\)[ \t\n]*" )
;; in my main .emacs file, and this makes auto-capitalization.el work for me.

;; Maybe this is related to bug 4153 which is reported as fixed in emacs head?

No, it is totally unrelated.

Your issue is explained in the NEWS for Emacs 22, and in the documentation
of the variable sentence-end:

  The value nil means to use the default value defined by the
  function `sentence-end'.  You should always use this function
  to obtain the value of this variable.

So auto-capitalize should use sentence-end the function, not the variable.
