Description:
------------
The exec() call is supposed to return the output of the system call
into the second parameter.
However, it modifies this output. It behaves as if rtrim() is called on
each line. This causes data loss because rtrim() is not reversible.
Reproduce code:
---------------
<?
header ('Content-type: text/plain');
file_put_contents ('temp', " "); // also reproducible with "\t"
exec ("type temp", $ops, $result);
echo var_export ($ops, true);
?>
Expected result:
----------------
array (
0 => ' ',
)
Actual result:
--------------
array (
0 => '',
)
