Whitespace is no longer a valid delimiter (older Perls allowed it), and there are already measures taken to advance past the whitespace. In addition, " " is not a special case character like the brackets are. Therefore, I'll hazard a guess and say they're in there for readability. And because 5 is such a better offset than 4.
