Bug : Bogus spam detection with SpamGroups

Hi all!

I was trying to test detection with usage of SpamGroups 
feature and was a bit surprised to see that all my 
messages are spam :)

Digging into the problem, I figured out, the false 
positive comes from 'SpamAssassin' group and the way how 
it checks for spam:

Mail::Message::Head::SpamGroup:39:

if(my $f = $head->get('X-Spam-Flag') || 
$head->get('X-Spam-Status'))
{   $spam = $f =~ m/yes/i;                          
}

And here is how my SA reports:

X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on 
com.bat.ru
X-Spam-Level: 
X-Spam-Status: No, hits=0.2 required=5.0 
tests=BAYES_44,NO_REAL_NAME 
	autolearn=no version=2.63

Notice big fat 'YES' in the word BAYES...

So, I think, the test should be adjusted to be more 
strict... 

Another nice option would be possiblitiy to define number 
of '*' in the X-Spam-Level: to mark message as spam... 
Although it can be done in subclass, I guess..
