I could not find any POSIX support for console width, in termios(3), stty(1) or 
anywhere else.

The "size" parameter to "stty" is a GNU/coreutils extension and a convenience 
wrapper to the Linux-specific ioctl() for shell scripting. In other words, the 
current code is not portable, but the previous code was even less so.
