Description:
------------
The following code reports 2 memleaks:

/opt/cvs/php5/ext/tidy/tidy.c(364) :  Freeing 0x00415C70 (16 bytes), 
script=/usr/local/bxphp/apache/htdocs/tidy.php
/opt/cvs/php5/ext/tidy/tidy.c(357) :  Freeing 0x00415C20 (16 bytes), 
script=/usr/local/bxphp/apache/htdocs/tidy.php
=== Total 2 memory leaks detected ===

First one for the array_merge code (if I remove the array_merge, the 
memleak disappears)

The second one for the 3rd param as an element of the 2nd param 
array. If I just add the value "utf8" there, it doesn't memleak.

Don't question the code, it's just a stripdown of a more complex one ;)

Reproduce code:
---------------
$html = "foo";
$options = array("char-encoding" => "utf8","drop-proprietary-attributes" => "yes");
$options2 = array("drop-proprietary-attributes" => "no");
$options = array_merge($options,$options2);
 
$tidy = new tidy();
$tidy->parseString($html,$options,$options['char-encoding']);
print $tidy;
