Comment (by raimue at macports.org):

 I tried the `stty -f /dev/stdout` approach today. But it does not seem to
 work, I always get a "Permission denied" error.

 So it needs an extension in Pextlib. I will look into determining the
 current size of the terminal using something like:
 {{{
 #include <sys/ioctl.h>
 struct winsize = {0, 0, 0, 0};
 ioctl(STDOUT_FILENO, TIOCGWINSZ, &s);
 }}}
