goto breaks the lua2js file

[KinuTheDragon]

When using a goto in my Lua code, the lua2js tool dies with the following error message:

    throw new Error(str);
    ^

Error: Parse error on line 4778:
... == 0 then               goto stop           end       if id
----------------------^
Expecting '(', ':', '.', 'STRING', '{', '[', got 'NAME'

I'll see if I can fix this by changing my Lua code to not use goto. (I didn't write the code; I'm just modifying it.)
