Not parsing MMM for Apr and Aug

```
What steps will reproduce the problem?
1. Date.parse("15 Aug 2009")
2. Date.parse("15 Apr 2009")
3.

What is the expected output? What do you see instead?
Expected:Wed Apr 15 2009 00:00:00 GMT+1100 (AUS Eastern Daylight Time)
Actual:Wed Apr 01 2009 00:00:00 GMT+1100 (AUS Eastern Daylight Time)
NB the day portion of the date says 01 not 15

What version of the product are you using? On what operating system?
1.0 Alpha-1
XP,Fir2fox3

Please provide any additional information below.
Seems to be just a problem with parsing the months starting with A, I
assume this is something to do with it interfering with the time parsing
and looking for an "a" token for AM. Just a guess though.
