Description:
------------
fputcsv() inserts a newline character at the end of string. This behaviour is not seen in the documentation. This happens for both php5 and php6 on windows as well as on RHEL.

Reproduce code:
---------------
<?php
$list = array ('aaa,bbb');
$fp = fopen("file.tmp", 'w');
var_dump(fputcsv($fp, $list));
var_dump( filesize("file.tmp") );
var_dump( file_get_contents("file.tmp") );
fclose($fp);
?> 


Expected result:
----------------
int(9)
int(9)
string(9) ""aaa,bbb""


Actual result:
--------------
int(10)
int(10)
string(10) ""aaa,bbb"
