The 256-colors aren't shown since the corresponding terminfo expression
doesn't map to termcap.  (I added a workaround recently in ncurses to
recognize this special case).  For example

xterm+256color|xterm 256-color feature:\
        :cc:\
	:Co#256:pa#32767:\
	:AB=\E[48;5;%dm:AF=\E[38;5;%dm:Sb@:Sf@:
