[lltx] luatex -recorder doesn't work properly

[Linas Stonys]

Hi,
luatex -recorder option doesn't write ".lua" files to ".fls".
>luatex --version
This is LuaTeX, Version beta-0.76.0-2013061707  (TeX Live 2013/W32TeX) 
(rev 4627)


With this version --recorder works correct:
This is LuaTeX, Version beta-0.70.2-2012080612 (TeX Live 2012/W32TeX)

I think it's because of lua 5.2 standard functions (dofile, require, ...).
