http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html Assuming we want this, there is also LINES. We have tools that do not even look at COLUMNS and LINES in the tree. For instance, tmux, systat, top, pkg_add, dpb. So, does it make sense to put COLUMNS and SIZE forward ? I think this is the first important question to ask... (I remember having COLUMNS and LINES hardcoded in my old, old .profile around SunOS4... we can probably assume this is gone now)
