IMHO, this is a documentation issue. Color output must not be assumed to be on by default: this would not be conforming and would probably break many scipts. I don't think that this should also be on for TTY, as this could break the use of tools like "expect". The above paragraph could mention the --color option. -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
