There are two bugs in the implementation of options %U and %W (week of
the year) in cftime and ascftime:

- In a year which starts on a Monday (wday=1), %U becomes 3 instead of 2
 on the 2nd week, thus ends up having 53 weeks, with a partial 54th week
 at the end.  The same thing happens to %W in a year which starts on a Tuesday.

- The initial partial week of the year (3 days or less, if a year starts
 on a Thursday for %U, Friday for %W) is always computed as week 52 of the
 previous year, even though by cftime's own reckoning it may be week 53.

(Note: these formats are a rather new addition, and might not exist on 
some systems.  On the other hand, later systems may have fixed these bugs
already.  Please do not flame me in either case).
