I looked there too, but did not find any reference either.

For some reason I had the impression what I was asking for is common 
practice. There is also a recent commit where Craig added braces, which 
seems to match the change we discuss here:

r190982 - Use curly braces all the way through long if/else chain for 
consistency and readability.

On the other hand, I was looking at the LLVM source files and there does 
not seem to be a consistent pattern (I did not count which style is more 
comment). As we both seems to mention this in a code review, it might be 
useful to clarify it in the coding style document. I have no strong 
opinion in either direction.

Cheers,
