Here are some proposed minor patches for africa, europe, northamerica:
* Add a mistakenly omitted autumn 1946 DST transition for Spain.
* Correct the entries for France and French colonies before 1911.
(I found a more authoritative source for Paris Mean Time.)
* Sort country entries properly in `europe'.
* Update reference to obsolescent name in `northamerica'.
