There are some false positives, yes, but on the whole, sending out  
such messages helps us find and fix breakage faster. That's good for  
LLVM as a project and as a community.

I'm sure the BuildBot owners would be happy to have help improving the  
heuristics on these messages, e.g., to ignore changes to documentation.
