-Think carefully about whether your change requires updating the
-documentation. If it does, you can either do this yourself or add an
-item to the NEWS file.
-
-If you document your change in NEWS, please mark the NEWS entry with
-the documentation status of the change: if you submit the changes for
-the manuals, mark it with "+++"; if it doesn't need to be documented,
-mark it with "---"; if it needs to be documented, but you didn't
-submit documentation changes, leave the NEWS entry unmarked. (These
-marks are checked by the Emacs maintainers to make sure every change
-was reflected in the manuals.)
