Description:
------------
I'm using the parse_ini_file() function as the basis for a reimplementation of get_browser(). I'm having to process browscap.ini without using the get_browser() function as the hosting people I'm using won't set the browscap path in php.ini. Until fairly recently this was working fine.

I'm receiving parse errors on the browscap.ini against the "browser=Yahoo! Slurp" line, the same as Gary Keith mentions in one of his comments in Bug #27291 [get_browser matches browscap.ini patterns incorrectly].

The browscap.ini section that causes this reads:
  [Mozilla/5.0 (compatible; Yahoo! Slurp; http://help.yahoo.com/help/us/ysearch/slurp)]
  parent=Yahoo
  browser=Yahoo! Slurp

From the ChangeLog and #27291's comment listing, issues with get_browser() have apparently been fixed in 4.3.5.

However, I'm not using get_browser(), and so I was wondering if the fix implemented for that will also remedy the parse_ini_file() issue? For example, does get_browser() call parse_ini_file() [or does the engine do something along those lines]?

Oh, BTW, editting the browscap.ini manually so that "browser=Yahoo Slurp" rather than the sourced "browser=Yahoo! Slurp" causes everything to function properly.

The hosting people are running under PHP 4.3.4 at the moment.

Reproduce code:
---------------
function browserCapabilities($userAgent, $browscapLocation) {

  [..Some initialisation if variables..]

  print "      Processing: $userAgent\n";
  $this->browscapFile = parse_ini_file ($browscapLocation, TRUE);

  [..Some array processing..]

  [.. Print statements for browser capabilities..]

}

Expected result:
