Description:
------------
When writing CLI scripts, one typically adds a shebang to the beginning of the 
script. When the script is executed, the shebang is not outputted.

On occasion, it's useful to include another CLI script. When the file is included, 
the shebang on the included file is outputted, contrary to expected behavior.

Test script:
---------------
file1.php:
#!/usr/bin/php
<?php
echo "Including file2\n";
include 'file2.php';
?>

file2.php:
#!/usr/bin/php
<?php
echo "Inside file2\n";
?>

Expected result:
----------------
Including file2
Inside file2

Actual result:
--------------
Including file2
#!/usr/bin/php
Inside file2
