Totally trivial comment inline.

Given the stalled nature behind the fixes, if you could spin a v4 with
this minor stuff addressed that would be great. FWIW under normal circumstances
I'd probably just have tweaked most of them whilst applying.

The double line break doesn't seem locally consistent.  A double break seems
to be reserved for before sections with === level titles only.
