So you are confusing the interpreter with the language.  Look here:

dak@lola:~$ lua
Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio
> local x=1
> print(x)
nil

Does this tell us that in Lua local assignments end at a newline?  Of
course not.  It tells us something about how the interpreter divides its
input into separate units.

If you want to make a statement about the function of \n in the Lua
language, please write it into a complete file you feed into Lua (and
obviously not via input redirection).
