Yes, that indentation-by-16 went off the rails.  We should probably fix that the 
next time we happen to be changing the neighborhood.

I've tried to avoid making global style changes even when I thought they would 
improve the code.  Part of this is to avoid unwanted differences (diff -bw does 
not suffice, unfortunately), and part is out of respect to the previous 
maintainer, who has a distinct style that I'm loath to discard everywhere merely 
because it has problems somewhere or because it grates on me.  For my own 
changes, though, I haven't hesitated to use a slightly different style that I 
think works better; this is not recent practice, as I recall doing that even 
with code I contributed many years ago.
