"monday +2week" equivalent to "+2days"

```
What steps will reproduce the problem?
1. Type "monday +2week"

What is the expected output? What do you see instead?
Expected output: ideally, two weeks from the following monday (although
given a previous issue I've raised, even "monday" or "+2week" would be
*more* expected; "+2 days" is just bizarre.

What version of the product are you using? On what operating system?
Firefox 2, OS X 10.5.1
```
