Description:
------------
Line feed following a closing tag ?> is not actually reproduced in the output buffer.

When a space follows a closing tag, there is no problem, but when it is a line feed character, it seems not to be taken in consideration ?

Reproduce code:
---------------
<?php
$aaa='aaa';
$bbb='bbb';
$ccc='ccc';
?>

<pre>
line 1: aaa
line 2: bbb
line 3: ccc
</pre>

<pre>
line 1: <?php echo $aaa; ?>
line 2: <?php echo $bbb; ?>
line 3: <?php echo $ccc; ?>
</pre>

Expected result:
----------------
line 1: aaa
line 2: bbb
line 3: ccc

line 1: aaa
line 2: bbb
line 3: ccc

Actual result:
--------------
line 1: aaa
line 2: bbb
line 3: ccc

line 1: aaaline 2: bbbline 3: ccc
