Doing @highlight_string seems to work to, but it strips the \. Might
not fixing, but it still seems like a bug.

If you just want to suppress warnings, error_reporting(0) might help
you. I'm not sure if this needs to be fixed anyhow though...

Description:
------------
Given a string that contains this PHP code:

<?php
$a = 2;
\;
$b = 3;
?>

Then highlight_string() generates this:

<?php
$a = 2;

Warning: Unexpected character in input:  '\' (ASCII=92) state=1 in
/home/kjartan/scripts/highlight_string on line 9
;
$b = 3;
?>

Granted its not valid PHP, but should hightlight_string() function as a
PHP validation system? Not that it does a good job at it as this gets
colored just fine:

<?php
$a = 2
$b = 3
$c = 5
?>

What gives?

Reproduce code:
---------------
<?php
$string = '<?php
$a = 2;
\
$c = 5;
?>';

highlight_string($string);


Expected result:
----------------
I expect it to just leave the \ alone and not cause warnings.
