Description:
------------
I really don't understand how it "If safe mode is enabled, the uid of the script is ADDED to the realm part of the WWW-Authenticate header." increase security. And why this behavior is not optional (without disabling all safe_mode restriction).

About other strange behavior of this functionality (for my point of view) see below.



Reproduce code:
---------------
safe_mode=On / pcre=enabled

1. Example 34.1. Basic HTTP Authentication example from http://www.php.net/manual/en/features.http-auth.php

2. Example 34.2. Digest HTTP Authentication example from http://www.php.net/manual/en/features.http-auth.php

Expected result:
----------------
1. Consider of docs the note "If safe mode is enabled, the uid of the script is ADDED to the realm part of the WWW-Authenticate header." I expect realm=uid My Realm or realm=My Realm uid


2. Digest http auth ;)

Actual result:
--------------
1. realm=uid
I.e. php REPLACING realm at safe_mode=on with uid of script.

2. Always changed to Basic http auth

The reason is to prevent stealing auth session from independent directories on the same host and we won't change anything related to that as safe_mode is being removed with PHP 6.
