Description:
------------
The PHP tokenizer includes the first whitespace character after the opening php tag as a part of the opening tag. That is, the following code with one whitespace in between will be tokenized into two tokens, a start tag and a closing tag:
<?php ?>

While with two whitespaces in between will be tokenized into three tokens, an opening tag including one space character, a whitespace token with one space character and a closing tag:
<?php  ?>

I hope the whitespace doesn't get lost when I submit this ;-)

Reproduce code:
---------------
<?php
$source = "<?php ?>";
$tokens = token_get_all($source);
if($tokens[1][0] == T_WHITESPACE) {
  print "Whitespace found\n";
} else {
  print "Whitespace not found\n";
}
?>


Expected result:
----------------
Whitespace found

Actual result:
--------------
Whitespace not found
