Description:
------------
If I set the third parameter of the parse_ini_file function to INI_SCANNER_RAW, 
then the ini file has to end with a newline, else it will trigger a "syntax error, 
unexpected $end" warning.
The same ini file works with the default scanner_mode(INI_SCANNER_NORMAL), so I 
think this is a bug.

Test script:
---------------
<?php
$ini_array = parse_ini_file("test.ini", true, INI_SCANNER_RAW);


Expected result:
----------------
no warning

Actual result:
--------------
Warning: syntax error, unexpected $end ...
