Description:
------------
I have found unexpected behaviour in PHP 5.1.0.

Escaping braces in strings doesn't work as in previous version.

Reproduce code:
---------------
$string="abc";

echo "... {$string} ...\n";
echo "... \{$string} ...\n";


Expected result:
----------------
php 5.0.5:

... abc ...
... {abc} ...


Actual result:
--------------
php 5.1.0:

... abc ...
... {$string} ...

This commit seems to be the cause:
http://cvs.php.net/diff.php/ZendEnine2/zend_language_scanner.l?r1=1.131.2.1&r2=1.131.2.2&ty=u

I give infos to ilia, he likes to fix that.

Behaviour is still not matched to the expected result.

Actual result (in php 5.5.9):
-----------------------------
... abc ...
... \{abc} ...

Another example:
----------------
print "\{ \$";

Expected result:
----------------
{ $

Actual result (in php 5.5.9):
-----------------------------
\{ $
