in repository elpa.
commit 25887f8f74710cf927fc91592ff9d347c0432a07
Author: Vincent Belaïche <vincent....@hotmail.fr>
Date: Sun Sep 14 11:20:55 2014 +0200
Document TeX-add-style-hook's new 3rd argument.
* latex.el (LaTeX-dialect): Correct doctstring for consistency
with definition of function TeX-add-style-hook.
* doc/auctex.texi (Simple Style): modify example with
'TeX-add-style-hook', so that 3rd argument is added. Modify @defun
of 'TeX-add-style-hook' also to document addition of 3rd argument.
