Ah, OK -- I found it slightly hard to follow the ones that get longer than a 
screenful or so, and I don't have my editor set to match them up nicely (though I 
might look into that).  It's something I'm accustomed to doing and seeing, and I saw 
no mention of it one way or another in Documentation/CodingStyle, so I didn't really 
give it a second thought.
