Thanks, I pushed this to the master branch.

In the future, please don't provide changes for ChangeLog files, we
generate ChangeLog files from the Git log.  I also made your commit
log message more detailed, per our conventions; please try to use the
same style in the future.  Finally, the NEWS entry should have been
marked with "---", as this change doesn't need to be documented in any
manual.
