Bug description:  strtotime('next month') resolving to the wrong month

Description:
------------
strtotime adds an extra month when using the phrase 
"this month" or "next month".  Using '+1 months' or '+0 
months' works fine, though.

And, no, I'm not adding a month to 'Jan. 30'.

Reproduce code:
---------------
echo date('Y-m-d', strtotime('last month'));
echo date('Y-m-d', strtotime('this month'));
echo date('Y-m-d', strtotime('next month'));

echo date('Y-m-d', strtotime('-1 months'));
echo date('Y-m-d', strtotime('+0 months'));
echo date('Y-m-d', strtotime('+1 months'));


Expected result:
----------------
2003-11-09
2003-12-09
2004-01-09

2003-11-09
2003-12-09
2004-01-09


Actual result:
--------------
2003-11-09
2004-01-09
2004-02-09

2003-11-09
2003-12-09
2004-01-09
