Heading translation in `sed`

Let's take that slower.

        1 { h; d }

        /^\(.\)\1\1*$/ { x; 
                         y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/;
                         x; d;
                       }
        x;
        $ { p;x; }

Well, it's a little better.
