From manual page: http://www.php.net/function.output-add-rewrite-var
---

If ob_start() has already been called and output_add_rewrite_var() is called after that it leads to ob_get_level() == 2.

Manual states that this should be the case only if no buffering is active.

Bug is reproducable in CLI as well as CGI mode.

Test script:
---------------
<?PHP
ob_start();

echo "Fill buffer\n";

output_add_rewrite_var('someParam', 1);

echo "Level: " . ob_get_level() . "\n";

echo ob_get_clean();


Expected result:
----------------
Fill buffer
Level: 1


Actual result:
--------------
Fill buffer
Level: 2
