When running:
```
datetime.strptime('2013 23', '%Y %W')
```
The result is `datetime.datetime(2013, 1, 1, 0, 0)`. When running:
```
datetime.strptime('2013 23 1', '%Y %W %w')
```
The result is `datetime.datetime(2013, 6, 10, 0, 0)`.

It seems that `%W` is ignored, unless `%w` is also provided. But instead of throwing an error, a result is returned that is needlessly inaccurate. It could (and should?) return the first day of the week as a default, if an error is undesirable. Similar to:
```
datetime.strptime('2013 3', '%Y %m')
```
