Description:
------------
According to the docs "By default, the value of $_SERVER['HTTP_USER_AGENT'] is used". However, setting this to a different value does not change the output of get_browser with no arguments. Indeed, under CLI SAPI, HTTP_USER_AGENT is not set initially, and even if you set it by hand before calling get_browser() it still gives an error that it is not set.

Reproduce code:
---------------
Run from CLI SAPI:
<?
$_SERVER["HTTP_USER_AGENT"] = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.7.10) Gecko/20050717 Firefox/1.0.6";
echo is_object(get_browser($_SERVER["HTTP_USER_AGENT"])) ? "Y" : "N";
echo is_object(get_browser()) ? "Y" : "N";


Expected result:
----------------
YY

Actual result:
--------------
Y
Warning: get_browser(): HTTP_USER_AGENT variable is not set, cannot determine user agent name in /data/www/simon/Handbook/test.php on line 4
N

It does use the HTTP_USER_AGENT. But it does not use it from $_SERVER['HTTP_USER_AGENT'], this is a documentation error.
(you can't just change any pre-set $_SERVER values!)

You need to pass the function the different browser agent string if you think the one found in $_SERVER['HTTP_USER_AGENT'] isn't correct.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

"By default, the value of HTTP User-Agent header is used."
