Description:
------------
Using the mount() method brings in files/folders so that PHP scripts can use them internally. However, those files are not accessible through the Web server as the built-in files are. The directory structure should be as follows for the test below:

make.php = The test script below
internal.html = <p>From the inside</p>
external.html = <p>From the outside</p>
include.php = <?php include 'external.html'; ?>
test.phar = Will be built from the test script

Test script:
---------------
<?php
try {
    $p = new Phar('test.phar');
    $p->addFile('internal.html');
    $p->addFile('include.php');
    $p->setStub('<?php
Phar::webPhar("test.phar", "internal.html");
Phar::mount(__DIR__ . "/external.html", "external.html");
__HALT_COMPILER();');
    echo 'Done making test.phar';
} catch (Exception $e) {
    echo 'Exception caught: ' . $e->getMessage();
}
?>

Expected result:
----------------
Visiting: make.php
Done making test.phar

Visiting: test.phar/internal.html
From the inside

Visiting: test.phar/external.html
From the outside

Visiting: test.phar/include.php
From the outside

Actual result:
--------------
Visiting: make.php
Done making test.phar

Visiting: test.phar/internal.html
From the inside

Visiting: test.phar/external.html
404 - File /external.html Not Found

Visiting: test.phar/include.php
From the outside
