if conditional return "end" bug

[danielpza]

There seems to be a bug when a conditional returns "end" it would break the parser.

if condition then
  return "end"
end

See danielpza@8a4c013

Could you post the error stack? This is likely a bug in luaparse, though it might just be that we're using an old version.
