Description:
------------
PHP lexer omits end-of-line characters following T_END_HEREDOC token. This also causes incorrect output of highlight_string() function.

Reproduce code:
---------------
$code = '
<? 
  $x = <<<EOT
some string    
EOT
  $y = 2;
?>';

display_tokens(token_get_all($code));
highlight_string($code);



function display_tokens($tokens)
{
  foreach ($tokens as $token)
  { 
    if (is_array($token))
    {
      echo token_name($token[0]),"\n";
      echo $token[0]," '",htmlentities(addcslashes($token[1],"\n\r\t")),"'\n";
    }
    else
    {
      echo "    '",htmlentities($token),"'\n";
    }  
  }
}

----------------
