lualoader: Add note that \027 is a decimal representation

We've included an extra '0' in there (which might get removed later, but
it's maintained for the moment for legacy purposes) which oftentimes
indicate that the following number should be treated as octal. This is not
the case, so note that to prevent future confusion (of myself and others).
