While "--color=tty" works, "tty" is not a valid value for "--color" according to both "man ls" and "ls --help"; could be better to use the documented "--color=auto" instead. Patch attached.
Created attachment 295094 [details] Use --color=auto instead of --color=tty
Thanks for suggestion, it's the same option, but documented - so it will be really good to use it instead of tty. Built as coreutils-6.10-8.fc9 , closing RAWHIDE.
