bug#21259: Regex of (this)pagestyle in TeX-complete-list

Hi all,

if I start emacs with `emacs --eval '(setq debug-on-error t)' &' type
the following a tex file:


I get this error:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (error "Can't find completion for 
  signal(error ("Can't find completion for \"\\thispagestyle{\""))
  error("Can't find completion for \"%s\"" "\\thispagestyle{")
  call-interactively(TeX-complete-symbol nil nil)
--8<---------------cut here---------------end--------------->8---

It is due to a bug in the definition of `TeX-complete-list' in
`latex.el' (line 5913):

--8<---------------cut here---------------start------------->8---
(setq TeX-complete-list
      (append '(;; snipped
                 1 LaTeX-pagestyle-list "}"))
--8<---------------cut here---------------end--------------->8---

The number refers to the wrong subgroup in the regex.  There are two
ways to fix this: Make `\\(this\\)' a shy-group or replace `1' with `2'.

Please find attached a patch going the second route since it looks more
coherent to the rest of definitions in `TeX-complete-list'.  

As always, any comments welcome.

Best, Arash
