Bug description:  strtotime "weekday" keyword yields false results on weekends

Description:
------------
In strtotime, using the keyword "weekday" to calculate a date yields false
results when:
  - starting from a weekend date (including Friday)
  - AND end date lands on a weekend



Reproduce code:
---------------
<?php
     echo date("Y-m-d", strtotime("2009-03-20 +5 weekday"))."\n";
     //EXPECT: 2009-03-27.  RETURNS: 2009-03-29


     echo date("l", strtotime("friday +5 weekday"))."\n";
     //EXPECT: "Friday".  RETURNS: "Sunday"


     ## Works fine as long as start date is not a weekend...
     echo date("l", strtotime("thursday +6 weekday"))."\n";
     //EXPECT: "Friday".  RETURNS: "Friday"

     ## ...OR end date does not land on weekend:
     echo date("l", strtotime("friday +4 weekday"))."\n";
     //EXPECT: "Thursday".  RETURNS: "Thursday"
?> 

Expected result:
----------------
2009-03-27
Friday
Friday
Thursday

Actual result:
--------------
2009-03-29
Sunday
Friday
Thursday
