Both look pretty reasonable to me. Obviously it's a pretty trivial
change, but that's sort of the point: automate these things away so we
don't have to think about them during review.

Now if you could figure out a way to point people to FLEX_ALLOC in the
first place when they are not currently using it, _that_ would be pretty
amazing. But I suspect it's a bit too complicated. :)
