* australasia (Fiji): Tweak spring-forward transitions to match
timeanddate.com's predictions.
* newtzset.3: Adjust Fiji example to match updated predictions.
Reword examples so that the English descriptions are more

contents.

# For now, guess a pattern of the penultimate Sundays in October and January.
# From Paul Eggert (2013-09-09):
# For now, guess that Fiji springs forward the Sunday before the fourth
# Monday in October. This matches both recent practice and
# timeanddate.com's current spring-forward prediction.
# For the January 2014 transition we guessed right while timeanddate.com
# guessed wrong, so leave the fall-back prediction alone.
