Subject: [PATCH] Fix Vanuatu DST in 1973-1974 and 1984 transition
(Thanks to P Chan.)
* NEWS: Mention this.
* australasia (Vanuatu): DST was observed for three months in 1973-1974.
Spring 1984 transition was on 1984-09-23, not 10-23. Prefer Sat>=22
24:00 to Sun>=23 0:00 as that better matches the legal text.
