[Bug-AUCTeX] 11.86; TeX-source-correlate-determine-method doesn't find LuaTeX 0.70's --synctex

[Christoph LANGE]

Dear AUCTeX developers,

sorry, once more, the right way.

When TeX-source-correlate-determine-method in tex.el performs a 
(string-match "^[ ]*-synctex" ...) against the output of "lualatex 
--help", it doesn't find the "synctex" option.

This is because the LuaTeX output is different:

--- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< ---
$ lualatex --version
This is LuaTeX, Version beta-0.70.1-2012081406

...

$ lualatex --help

...

  The following regular options are understood:

   --synctex=NUMBER              enable synctex
--- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< ---

So the regular expression should be changed to "^[ ]*-?-synctex".
