note 29393 added to function.strtr

Interesting little thing I have noticed. Can anyone tell me why this happens? The code : $banned_words = array("spam" => "s**m",); $subject = strtr($subject,$banned_words); will only replace exactly "spam" with "s**m". Whereas, the code: $subject = strtr($subject,"spam","s**m"); will replace "spam", "Spam" & "spAM" with "s**m", but not "SPAM" which remains untouched. So. Question - why the difference in behaviour? Feature or bug? ;> And where is the case-insensitive strtr, please?
