I sent a message to the list already mentioning that after checking
perldoc -f split one more time I found where it mentioned using a quoted
literal space as the matching pattern. For some reason, it seems that
nobody saw the message, because I have seen several messages so far
quoting the releva

Igor just pointed out to me that it is, in fact, in perldoc -f split,
