Bug description:Weekdays with strtotime

Description:
------------
When using the relative "weekday[s]" string with strtotime() it returns 
inconsistent results, sometimes the date is the correct one, but some other
times 
it's wrong (it even returns weekend days).

Test script:
---------------
<?php

var_dump(PHP_VERSION);

$date = strtotime('2012-05-30'); // Wednesday

var_dump(date('Y-m-d (l)', strtotime('+1 weekdays', $date)));
var_dump(date('Y-m-d (l)', strtotime('+6 weekdays', $date)));
var_dump(date('Y-m-d (l)', strtotime('+8 weekdays', $date)));
var_dump(date('Y-m-d (l)', strtotime('+9 weekdays', $date)));
var_dump(date('Y-m-d (l)', strtotime('+10 weekdays', $date)));

$date = strtotime('2012-05-31'); // Friday

var_dump(date('Y-m-d (l)', strtotime('+1 weekdays', $date)));
var_dump(date('Y-m-d (l)', strtotime('+6 weekdays', $date)));
var_dump(date('Y-m-d (l)', strtotime('+8 weekdays', $date)));
var_dump(date('Y-m-d (l)', strtotime('+9 weekdays', $date)));
var_dump(date('Y-m-d (l)', strtotime('+10 weekdays', $date)));

Expected result:
----------------
string(5) "5.2.5"
string(21) "2012-05-31 (Thursday)"
string(21) "2012-06-07 (Thursday)"
string(21) "2012-06-11 (Monday)"
string(19) "2012-06-12 (Tuesday)"
string(22) "2012-06-13 (Wednesday)"
string(19) "2012-06-01 (Friday)"
string(19) "2012-06-08 (Friday)"
string(19) "2012-06-12 (Tuesday)"
string(19) "2012-06-13 (Wednesday)"
string(21) "2012-06-14 (Thursday)"

Actual result:
--------------
string(5) "5.2.5"
string(21) "2012-05-31 (Thursday)"
string(21) "2012-06-07 (Thursday)"
string(21) "2012-06-09 (Saturday)"
string(19) "2012-06-10 (Sunday)"
string(22) "2012-06-13 (Wednesday)"
