You cannot have one function (lua_allocstring), because when you 'add' a string in the Lua VM it does a hash and keep it unique, etc. So if you want to add a string in the Lua VM you need to have its content.
That is why my idea of proposal was to dissociate the allocation part (prepstring) from the addition to the LuaVM part (push prepstring)
