The change made by commit v3.4.0-rc1~342^2 (Factor an <INCLUDES>
placeholder out of <FLAGS> in rule variables, 2015-07-13) affects an
internal interface. Since it is commonly used by projects anyway, add a
release note covering the change in placeholders.
Move all development release notes into a new version-specific document:
tail -q -n +3 Help/release/dev/* > Help/release/3.4.rst
git rm -- Help/release/dev/*
except the sample topic:
git checkout HEAD -- Help/release/dev/0-sample-topic.rst
Reference the new document from the release notes index document.
Add a title and intro sentence to the new document by hand.
