Description:
------------
I'm reporting a documentation comment that was rejected but should be
valid.

"Note that since return() is a language construct and not a function, the parentheses surrounding its arguments are not required."

Far from optional, the parentheses actually cause an error when used as described in the documentation regarding include/require.

Reproduce code:
---------------
test1.php
<?php require 'test2.php'; ?>

test2.php
<?php return(); ?>

Actual result:
--------------
PHP Parse error:  syntax error, unexpected ')' in test2.php on line 1
