Alas, things sometimes don't divide that cleanly - sometimes an API
change/addition is part of fixing a bug rather than a new feature in
its own right.
A custom merge function along the lines of the one you suggest (i.e.
if it's after a section header in 3.2.x Misc/NEWS, add it after the
first occurrence of the same header in 3.3) is probably the way to go.
