Worth squashing a double blank line while here?

Interesting conditional; it's because of the static inline fallbacks
that are also conditional.  Makes sense.  An alternative would be having
the fallbacks be in a .c rather than static inline in the .h, but it
doesn't bother me enough to worry about it.

My R-b stands whether or not you make more whitespace tweaks.
