Replacing LUA_GLOBALSINDEX when porting 5.1 libs to 5.2...

[duck <duck@...>]

Can this 5.1 code:

    lua_getfield(L, LUA_GLOBALSINDEX, name);

be made ready for 5.2 by writing this instead:

    lua_pushglobaltable(L);
    lua_getfield(L,-1,name);
    lua_remove(L,-2);

?

(Apologies if this has been covered before. A mail archive search 
suggested it hadn't.)
