ls -color on dumb terminals

[Kolyan]

This problem stays more than two years (There is bugreport in 2001 in
bug-fileutils). How long will you disappoint users with functionality,
declared in /etc/DIR_COLORS? User can't choose, which terminals are color,
which are not.
Even in dumb terminal, which doesn't support color seqeuences user get

[0mfile_nam[0fd [0mfile_nam[0fd [0mfile_nam[0fd [0mfile_nam[0fd

with "ls --color". But this command is alias to ls in most systems.
Developers must do somthing with this situation. At least, use three lines
to determine, has terminal bold mode or not.
