Description:
------------
When calling token_get_all with a string containing heredoc strings, T_END_HEREDOC element contains two semicolons separated by newline and is  followed by semicolon character.
This does not happen if heredoc string is followed by concatenation operatior


Reproduce code:
---------------
=====================
code.php
=====================
<?php
      $x=<<<DD
  jhdsjkfhjdsh
DD
."";
      $a=<<<DD
  jhdsjkfhjdsh
DD;
  echo $a;
?>

=====================
test.php
=====================
<?php
  $tokens=token_get_all(file_get_contents("test.php"));
  print_r($tokens);
?>

Expected result:
----------------
Array
