Description:
------------
fgetcsv() breaks reading when a line has no cdata (eg. \n\n)

Reproduce code:
---------------
<?php
	
	$fn = tempnam( '/tmp', 'test' );
	if( $fp = fopen( $fn, 'w' ) ) {
		fwrite( $fp, "one;val1\ntwo;val2\n\nthree;val3\n" );
		fclose( $fp );
		
		if( $fp = fopen( $fn, 'r' ) ) {
			$items = array( );
			while( $d = fgetcsv( $fp, 4096, ';' ) ) {
				$items[] = $d;
			}
			fclose( $fp );
			var_dump( $items );
		}
	}
	
?>

Expected result:
----------------
$items-count of 4 

Actual result:
--------------
$item-count of 2
