Insure there's at least one space between stats in .lol files

The format string used did not insure there was any space between fields leading to very hard to parse stats, like this:
User          2  SSH      12:25 12:39  14554  0  0  0  0  0

That's 554 msgs read in 14 minutes online, but well, you see what I'm say'n.
