I don't know about you, but my first sentence (i.e. up to \n\n) is
essentially what I put into NEWS anyway so making it work so that
developer details go after that is not really an issue. Yes, coming up
with a way to flag commits as not NEWS-worthy would be needed, but I
don't think that would be difficult.

I sent a followup email to myself but unfortunately Gmail sent it from
another address so it got rejected.

I think that's overly complicated. I don't see why we need anything
more than simply NEWS/3.4, NEWS/3.3, etc. and just split the files per
feature release since that's the interest (and merge) boundary. And do
we really need a merged NEWS file at that granularity?
