Bug #104346 for DateTime-Format-ISO8601: parsing 1991-W01 throws exception

Subject:

parsing 1991-W01 throws exception

From the documentation it is unclear to me what "1991-W01" indicates but parsing "1991-W01" throws an exception while "1991-W02" parses.

Confirming: Tried all possible variations of week parsing I saw mentioned, can't get any of them to work in the proximity of week 1.

Week 54 ( which doesn't actually exist ) fails in a similar way, but Week 53 does not.

I'm guessing this is an off by one error in __normalize_week(). It would be great if someone could dig into this.
