Description:
------------
feof() is failing to detect the end of file for a file containing a blank file ("\n" character only).
This behaviour is seen on php5 and php6 both.

Reproduce code:
---------------
<?php

$fp = fopen("file2.tmp", "w");
$csv_string = "\n";
fwrite($fp, $csv_string);
fclose($fp);

$fp = fopen("file2.tmp", "r");
var_dump( ftell($fp) );
var_dump( fgetcsv($fp) );
var_dump( ftell($fp) );
var_dump( feof($fp) );
var_dump( fseek($fp, 0, SEEK_END) );
var_dump( ftell($fp) );
var_dump( feof($fp) );
fclose($fp);
?>


Expected result:
----------------
int(0)
array(1) {
  [0]=>
  string(0) ""
}
int(1)
bool(true)
int(0)
int(1)
bool(true)

Actual result:
--------------
int(0)
array(1) {
  [0]=>
  string(0) ""
}
int(1)
bool(false)
int(0)
int(1)
bool(false)
