Description:
------------
One of my scripts failed because the built-in web server returned the IPv6 value in $_SERVER['REMOTE_ADDR'] with square brackets.

The value was '[::1]' (PHP 7.3RC1) instead of '::1' (PHP 7.2.4), although it is no used as a host here (see RFC 3986, 3.2.2).

BTW: Also filter_var('[::1]', FILTER_VALIDATE_IP) fails (as expected).

Test script:
---------------
echo $_SERVER['REMOTE_ADDR']

Expected result:
----------------
::1

Actual result:
--------------
[::1]

That seems to be an unintended side effect of fixing bug #76136.
