This is all ansi color, no curses. :)

I knew nothing beyond the basic 3x/4x and bold/reverse/underline/reset codes 
until I read that page. Like most things in programming, writing the patches 
forced me to learn.

The attached script will display the entire color palette. The last block of 
colors should always be grayscale. You have a broken TERM value if it is all 
blue/green colors. If you run it in a real 256 term and a 256 term pretending 
to be an 88 term, you will see that every color in the 88 term is in the first 
two blocks on the 256 term.
