Bug description:'Open php' tag at end of file causes 'syntax error, unexpected
$end'

Description:
------------
This probably is a known effect, but I will just open a bug so it can be
documented as such:

When you end a file with a PHP open tag '<?php', and there is no character
beyond the tag the parser chokes with an 'unexpected $end' parse error.

Curiously, a short tag '<?' (if enabled) used in such a way raises no
error.

This effect is of course also seen when you eval a string containing an PHP
open tag at the end of the string. (from there I originally stumbled on
this behaviour)

In PHP 5.3 the code behaves as expected, so someone probably already
spotted this one, or fixed the parser to be less nitty.

Test script:
---------------
<?php

Expected result:
----------------
Nothin

Actual result:
--------------
Parse error: syntax error, unexpected $end in test.php on line 1
