Description:
------------
in 5.0.4, if stream_eof() returns false, feof() returns true, in 5.1.0b3, if stream_eof() returns true, feof() returns true.

In addition to the small test below, a slightly larger real-world streams test is available in cvs at pear/PHP_Archive/tests/eof.phpt

Reproduce code:
---------------
<?php
class Mystream
{
    static $a = false;
    function stream_open()
    {
        return true;
    }

    function stream_eof()
    {
        var_dump(self::$a);
        return self::$a;
    }

    function stream_seek()
    {
        return true;
    }

    function stream_tell()
    {
        return 0;
    }
}
stream_wrapper_register('testing', 'Mystream');
$fp = fopen('testing://blah', 'r');
var_dump(1, feof($fp));
fseek($fp, 100);
Mystream::$a = true;
var_dump(2, feof($fp));
?>

Expected result:
----------------
bool(false)
int(1)
bool(true)
bool(true)
int(2)
bool(false)

Actual result:
--------------
bool(false)
int(1)
bool(false)
bool(true)
int(2)
bool(true)
