Correcting summary so as not to suggest an invalid ini setting is being used.

Description:
------------
When unit testing session-related code in a CLI environment, appropriate PHP
ini settings combined with passing false to session_cache_limiter can allow
sessions to be started even if output has been already sent.
Unfortunately, session_regenerate_id() fails unconditionally even when no
cookie headers would have been sent:
// session.c, session_regenerate_id
if (SG(headers_sent)) {
php_error_docref(NULL TSRMLS_CC, E_WARNING, "Cannot regenerate session id -
headers already sent");
RETURN_FALSE;
}
// session.c, php_session_reset_id
if (PS(use_cookies) && PS(send_cookie)) {
php_session_send_cookie(TSRMLS_C);
PS(send_cookie) = 0;
}
Is this just an oversight? Or intentional?
Test script:
---------------
<?php
ini_set( 'session.use_cookies', 0 );
ini_set( 'session.use_only_cookies', 0 );
ini_set( 'session.use_trans_id', 1 );
// Don't send headers!
session_cache_limiter( false );
echo 'test';
// Succeeds
session_start();
// Fails
session_regenerate_id();
?>
Expected result:
----------------
No warnings or errors.
Output:
test
Actual result:
--------------
testPHP Warning: session_regenerate_id(): Cannot regenerate session id -
headers already sent in /home/jesse.hallam/tmp/session_test.php on line 15
