Subject: ls / dircolors should support more than 8 colors

ls / dircolors should support more than 8 colors.

First, "dircolors -p" says:

# Below are the color init strings for the basic file types. A color init
# string consists of one or more of the following numeric codes:
# Attribute codes:
# 00=none 01=bold 04=underscore 05=blink 07=reverse 08=concealed
# Text color codes:
# 30=black 31=red 32=green 33=yellow 34=blue 35=magenta 36=cyan 37=white
# Background color codes:
# 40=black 41=red 42=green 43=yellow 44=blue 45=magenta 46=cyan 47=white

But one can get bright colors without bold by using 90, 91, etc.
This is useful with gnome-terminal.

I think that this should be documented.

Support for more than 16 colors could be nice...

Actually this is also a lack of documentation. After looking at
"tput setaf ..." and "tput setab ..." output in 256-color mode,
one can use things like:

  38;5;<foreground color number>;48;5;<background color number>
