Heh. We can probably tweak the heuristics (one of the _great_ things about 
content detection is that you can fix it after the fact, unlike the 
alternative).

That said, I've personally actually found the content-based similarity 
analysis to often be quite informative, even when (and perhaps 
_especially_ when) it ended up showing something that the actual author of 
the thing didn't intend.

So yeah, I've seen a few strange cases myself, but they've actually been 
interesting. Like seeing how much of a file was just a copyright license, 
and then a file being considered a "copy" just because it didn't actually 
introduce any real new code.
