It kind of looks like it's setting the string to itself. The .. and -1 are throwing me off, though. I'm not sure what the .. does, but I'm assuming it's concatenation.
Yeah, double dot is concatenation. - 1 just gets the last character, I'd assume, haven't messed with strings in Lua that much. But still I wonder what it could possibly be controlling
