[Mimedefang] Case in-sentitive matching

[Ashley M. Kirchner]

    In my sub filter, I have the following three lines:

    if (($type eq "text/plain") and 
$entity->head->mime_attr("content-type.charset") eq "Windows-1251") {
        return action_bounce("Charset Windows-1251 not accepted here");
    }

    ...which successfully bounces anything matching that charset.  
However, it's case sensitive.  Those that come in as "windows-1251" 
still get through.  Is there an easy way to match for both, without 
having to duplicate those three lines simply to add the lowercase version?
