Lua 5 Grammar update

[Klaas-Jan Stol <vanderlay@...>]

Hi,

for sake of completeness, I just updated the Lua wiki with a link to a 
Lua 5 grammar for Bison (or Yacc). I'm using this grammar in my attempt 
to write a Lua compiler targeting Parrot, the new virtual machine for 
Perl6. I'm pretty sure it's complete. Lua has 1 ambiguity, as described 
in the reference manual, this same ambiguity is also present in this 
grammar file. In this file, it is present as a shift/reduce conflict, 
resolved by default by a "shift". Adding a semicolon will result in a 
"reduce". (this is pretty much the same behaviour as in original Lua, I 
think).

kind regards,
