Description:
------------
If a template variable is assigned a value containing a substring enclosed in braces, that substring is eaten when the template is rendered.

This bug arose in a program that attempts to display php
source files and templates in a nice way, using templates.
The strings in question arose because the contents of the template files were assigned as the values of template variables in the viewing program.

Reproduce code:
---------------
foo.php:
--------
<?php

require_once "HTML/Template/IT.php";

$template = new HTML_Template_IT(".");
$template->loadTemplatefile("foo.tpl", true, true);
$template->setCurrentBlock("FOO");
$template->setVariable("FOO", "This is a {FOOBAR} foo!");
$template->parseCurrentBlock();
$template->show();

?>
------------------

foo.tpl:
--------
<html>
<body>

This is a foo!

</body>
</html>
-------

Expected result:
----------------
<html>
<body>

This is a {FOOBAR} foo!

</body>
</html>

Actual result:
--------------
<html>
<body>

This is a foo!

</body>
</html>

Note that the substring {FOOBAR} of the variable value
is replaced by a space.

Oops. The foo.tpl file should have been:

<html>
<body>
<!-- BEGIN FOO -->
{FOO}
<!-- END FOO -->
</body>
</html>

The default does not preserve variables in the results.

To change the default the default behiavior, see setOptions, or pass the option to the constructor:

array('preserve_data'=>true)
