Description:
------------
If I try to specify more than one include_path directive on
the command-line, only one sticks.  WIth the following two
command-lines, I expected to see two entries, but only saw
the first.

1. Default case -- I see all three entries from my php.ini
$ php test.php
include_path=.;C:\apps\xampp\php\PEAR;c:\apps\smarty\libs

$ php -d include_path=c:\php-5.2.8\PEAR;c:\php-5.2.8\PEAR\phpunit test.php
include_path=c:\php-5.2.8\PEAR

I was expecting to see both entries, not just the first.  I'd also
like an option to add to the existing include_path setting,
not just override it.


$ php -d include_path=c:\php-5.2.8\PEAR -d include_path=c:\php-5.2.8\PEAR\phpunit test.php
include_path=c:\php-5.2.8\PEAR\phpunit

Here I get the second entry only.

Test script:
---------------
<?php
print "include_path=";
print ini_get("include_path");
print "\n";
?>

Expected result:

Actual result:
