Description:
------------
There is a bug regarding whitespace surrounding opening/closing php tags when using the alternative syntax for switch() statements. If you try to insert a tab or spaces before the opening php tag for the first case statement (<TAB><? case 'one': ?>), php dies with "PHP Parse error:  syntax error, unexpected T_INLINE_HTML, expecting T_ENDSWITCH or T_CASE or T_DEFAULT". I realize that the only valid text between the 'switch' and first 'case' statement must be a 'case' or 'default' label, but whitespace should be an exception.

Reproduce code:
---------------
// Works if whitespace before "<? case 'one:': ?>" is removed

$var = 'one';
<? switch($var): ?>
    <? case 'one': ?>
        <p>switch found one</p>
	<? break; ?>
    <? case 'two': ?>
        <p>switch found two</p>
        <break; ?>
    <? default: ?>
        <p>switch found something else</p>
<? endswitch; ?>

Expected result:
----------------
<p>switch found one</p>

Actual result:
--------------
PHP Parse error:  syntax error, unexpected T_INLINE_HTML, expecting T_ENDSWITCH or T_CASE or T_DEFAULT in __FILE__ on line xxx
