this is why ncurses has the ability to split its lib into a smaller libtinfo.  
you get all the logic for detecting terminal capabilities without all the rest 
of the ncurses layers.  for people who do want to kill colors across the board, 
they can use a different TERM that does not support them.  forcing people to 
duplicate that in a new database seems wrong to me.
